About Installing 1
When you install vRealize Operations Manager, you can install the product in an environment that has
never been monitored by vRealize Operations Manager. You can also migrate, which captures an
environment monitored by a previous version of vRealize Operations Manager so that the new copy of
vRealize Operations Manager can monitor that environment.
You can migrate at installation time, or you can postpone a migration until after your copy of
vRealize Operations Manager is in production use. In other words, you can run
vRealize Operations Manager to monitor a fresh environment, and at any time, decide to add an
environment that was being monitored by a previous vRealize Operations Manager.

Sizing the vRealize Operations Manager Cluster
The resources needed for vRealize Operations Manager depend on how large of an environment you expect
to monitor and analyze, how many metrics you plan to collect, and how long you need to store the data.
It is dicult to broadly predict the CPU, memory, and disk requirements that will meet the needs of a
particular environment. There are many variables, such as the number and type of objects collected, which
includes the number and type of adapters installed, the presence of HA, the duration of data retention, and
the quantity of specic data points of interest, such as symptoms, changes, and so on.
VMware expects vRealize Operations Manager sizing information to evolve, and maintains Knowledge Base
articles so that sizing calculations can be adjusted to adapt to usage data and changes in versions of
vRealize Operations Manager.
Knowledge Base article 2093783
The Knowledge Base articles include overall maximums, plus spreadsheet calculators in which you enter the
number of objects and metrics that you expect to monitor. To obtain the numbers, some users take the
following high-level approach, which uses vRealize Operations Manager itself.
1 Review this guide to understand how to deploy and congure a vRealize Operations Manager node.
2 Deploy a temporary vRealize Operations Manager node.
3Congure one or more adapters, and allow the temporary node to collect overnight.
4 Access the Cluster Management page on the temporary node.
5 Using the Adapter Instances list in the lower portion of the display as a reference, enter object and
metric totals of the dierent adapter types into the appropriate sizing spreadsheet from Knowledge
Base article 2093783.
6 Deploy the vRealize Operations Manager cluster based on the spreadsheet sizing recommendation. You
can build the cluster by adding resources and data nodes to the temporary node or by starting over.
If you have a large number of adapters, you might need to reset and repeat the process on the temporary
node until you have all the totals you need. The temporary node will not have enough capacity to
simultaneously run every connection from a large enterprise.
Another approach to sizing is through self monitoring. Deploy the cluster based on your best estimate, but
create an alert for when capacity falls below a threshold, one that allows enough time to add nodes or disk
to the cluster. You also have the option to create an email notication when thresholds are passed.
During internal testing, a single-node vApp deployment of vRealize Operations Manager that monitored
8,000 virtual machines ran out of disk storage within one week.
Add Data Disk Space to a vRealize Operations Manager vApp Node
You add to the data disk of vRealize Operations Manager vApp nodes when space for storing the collected
data runs low.
Prerequisites
nNote the disk size of the analytics cluster nodes. When adding disk, you must maintain uniform size
across analytics cluster nodes.
nUse the vRealize Operations Manager administration interface to take the node oine.
nVerify that you are connected to a vCenter Server system with a vSphere client, and log in to the
vSphere client.
Chapter 1 About Installing
VMware, Inc. 9
Procedure
1 Shut down the virtual machine for the node.
2 Edit the hardware seings of the virtual machine, and do one of the following:
nIncrease the size of Hard Disk 2.
You cannot increase the size when the virtual machine has snapshots.
nAdd another disk.
3 Power on the virtual machine for the node.
During the power-on process, the virtual machine expands the vRealize Operations Manager data partition.
Complexity of Your Environment
When you deploy vRealize Operations Manager, the number and nature of the objects that you want to
monitor might be complex enough to recommend a Professional Services engagement.
Complexity Levels
Every enterprise is dierent in terms of the systems that are present and the level of experience of
deployment personnel. The following table presents a color-coded guide to help you determine where you
are on the complexity scale.
nGreen
Your installation only includes conditions that most users can understand and work with, without
assistance. Continue your deployment.
nYellow
Your installation includes conditions that might justify help with your deployment, depending on your
level of experience. Consult your account representative before proceeding, and discuss using
Professional Services.
nRed
Your installation includes conditions that strongly recommend a Professional Services engagement.
Consult your account representative before proceeding, and discuss using Professional Services.
Note that these color-coded levels are not rm rules. Your product experience, which increases as you work
with vRealize Operations Manager and in partnership with Professional Services, must be taken into
account when deploying vRealize Operations Manager.

About vRealize Operations Manager Cluster Nodes
All vRealize Operations Manager clusters consist of a master node, an optional replica node for high
availability, optional data nodes, and optional remote collector nodes.
When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment
to create role-less nodes. After the nodes are created and have their names and IP addresses, you use an
administration interface to congure them according to their role.
You can create role-less nodes all at once or as needed. A common as-needed practice might be to add nodes
to scale out vRealize Operations Manager to monitor an environment as the environment grows larger.
vRealize Operations Manager vApp Deployment and Configuration Guide
12 VMware, Inc.
The following node types make up the vRealize Operations Manager analytics cluster:
Master Node The initial, required node in vRealize Operations Manager. All other nodes
are managed by the master node.
In a single-node installation, the master node manages itself, has adapters
installed on it, and performs all data collection and analysis.
Data Node In larger deployments, additional data nodes have adapters installed and
perform collection and analysis.
Larger deployments usually include adapters only on the data nodes so that
master and replica node resources can be dedicated to cluster management.
Replica Node To use vRealize Operations Manager high availability (HA), the cluster
requires that you convert a data node into a replica of the master node.
The following node type is a member of the vRealize Operations Manager cluster but not part of the
analytics cluster:
Remote Collector Node Distributed deployments might require a remote collector node that can
navigate rewalls, interface with a remote data source, reduce bandwidth
across data centers, or reduce the load on the vRealize Operations Manager
analytics cluster. Remote collectors only gather objects for the inventory,
without storing data or performing analysis. In addition, remote collector
nodes may be installed on a dierent operating system than the rest of the
cluster.
About vRealize Operations Manager Remote Collector Nodes
A remote collector node is an additional cluster node that allows vRealize Operations Manager to gather
more objects into its inventory for monitoring. Unlike data nodes, remote collector nodes only include the
collector role of vRealize Operations Manager, without storing data or processing any analytics functions.
A remote collector node is usually deployed to navigate rewalls, reduce bandwidth across data centers,
connect to remote data sources, or reduce the load on the vRealize Operations Manager analytics cluster.
Remote collectors do not buer data while the network is experiencing a problem. If the connection between
remote collector and analytics cluster is lost, the remote collector does not store data points that occur
during that time. In turn, and after the connection is restored, vRealize Operations Manager does not
retroactively incorporate associated events from that time into any monitoring or analysis.
You must have at least a master node before adding remote collector nodes.
About vRealize Operations Manager High Availability
vRealize Operations Manager supports high availability (HA). HA creates a replica for the
vRealize Operations Manager master node and protects the analytics cluster against the loss of a node.
With HA, data stored on the master node is always 100% backed up on the replica node. To enable HA, you
must have at least one data node deployed, in addition to the master node.
nHA is not a disaster recovery mechanism. HA protects the analytics cluster against the loss of only one
node, and because only one loss is supported, you cannot stretch nodes across vSphere clusters in an
aempt to isolate nodes or build failure zones.
nWhen HA is enabled, the replica can take over all functions that the master provides, were the master to
fail for any reason. If the master fails, failover to the replica is automatic and requires only two to three
minutes of vRealize Operations Manager downtime to resume operations and restart data collection.
Chapter 1 About Installing
VMware, Inc. 13
When a master node problem causes failover, the replica node becomes the master node, and the cluster
runs in degraded mode. To get out of degraded mode, take one of the following steps.
nReturn to HA mode by correcting the problem with the master node. When a master node exits an
HA-enabled cluster, master node does not rejoin with the cluster without manual intervention.
Therefore, restart the vRealize Operations Analytics process on the downed node to change its role
to replica and rejoin the cluster.
nReturn to HA mode by converting a data node into a new replica node and then removing the old,
failed master node. Removed master nodes cannot be repaired and re-added to
vRealize Operations Manager.
nChange to non-HA operation by disabling HA and then removing the old, failed master node.
Removed master nodes cannot be repaired and re-added to vRealize Operations Manager.
nIn the administration interface, after an HA replica node takes over and becomes the new master node,
you cannot remove the previous, oine master node from the cluster. In addition, the previous node
continues to be listed as a master node. To refresh the display and enable removal of the node, refresh
the browser.
nWhen HA is enabled, the cluster can survive the loss of one data node without losing any data.
However, HA protects against the loss of only one node at a time, of any kind, so simultaneously losing
data and master/replica nodes, or two or more data nodes, is not supported. Instead,
vRealize Operations Manager HA provides additional application level data protection to ensure
application level availability.
nWhen HA is enabled, it lowers vRealize Operations Manager capacity and processing by half, because
HA creates a redundant copy of data throughout the cluster, as well as the replica backup of the master
node. Consider your potential use of HA when planning the number and size of your
vRealize Operations Manager cluster nodes. See “Sizing the vRealize Operations Manager Cluster,” on
page 9.
nWhen HA is enabled, deploy analytics cluster nodes on separate hosts for redundancy and isolation.
One option is to use anti-anity rules that keep nodes on specic hosts in the vSphere cluster.
If you cannot keep the nodes separate, you should not enable HA. A host fault would cause the loss of
more than one node, which is not supported, and all of vRealize Operations Manager would become
unavailable.
The opposite is also true. Without HA, you could keep nodes on the same host, and it would not make a
dierence. Without HA, the loss of even one node would make all of vRealize Operations Manager
unavailable.
nWhen you power o the data node and change the network seings of the VM, this aects the IP
address of the data node. After this point, the HA cluster is no longer accessible and all the nodes have
a status of "Waiting for analytics". Verify that you have used a static IP address.
nWhen you remove a node that has one or more vCenter adapters congured to collect data from a HA-
enabled cluster, one or more vCenter adapters associated with that node stops collecting. You change
the adapter conguration to pin them to another node before removing the node.
nAdministration UI shows the resource cache count, which is created for active objects only, but the
Inventory Explorer displays all objects. Therefore, when you remove a node from a HA-enabled cluster
allowing the vCenter adapters collect data and rebalance each node, the Inventory explorer displays a
dierent quantity of objects from that shown in the Administration UI.
vRealize Operations Manager vApp Deployment and Configuration Guide

Preparing for Installation 2
You preparing for your installation, consider some of these best practises, platform, and cluster
requirements.
This chapter includes the following topics:
n“Platform requirements for vRealize Operations Manager,” on page 15
n“Requirements,” on page 15
Platform requirements for vRealize Operations Manager
vRealize Operations Manager requires the following hardware and software when you install on any
platform.
Requirements
You have to consider important requirements while creating nodes in a vRealize Operations Manager.
Using IPv6 with vRealize Operations Manager
vRealize Operations Manager supports Internet Protocol version 6 (IPv6), the network addressing
convention that will eventually replace IPv4. Use of IPv6 with vRealize Operations Manager requires that
certain limitations be observed.
Using IPv6
nAll vRealize Operations Manager cluster nodes, including remote collectors, must have IPv6 addresses.
Do not mix IPv6 and IPv4.
nAll vRealize Operations Manager cluster nodes, including remote collectors, must be vApp based.
nUse global IPv6 addresses only. Link-local addresses are not supported.
nIf any nodes use DHCP, your DHCP server must be congured to support IPv6.
nDHCP is only supported on data nodes and remote collectors. Master nodes and replica nodes still
require xed addresses, which is true for IPv4 as well.
nYour DNS server must be congured to support IPv6.
nWhen adding nodes to the cluster, remember to enter the IPv6 address of the master node.
nWhen registering a VMware vCenter® instance within vRealize Operations Manager, place square
brackets around the IPv6 address of your VMware vCenter Server® system if vCenter is also using IPv6.
For example: [2015:0db8:85a3:0042:1000:8a2e:0360:7334]
VMware, Inc. 15
Note that, even when vRealize Operations Manager is using IPv6, vCenter Server may still have an IPv4
address. In that case, vRealize Operations Manager does not need the square brackets.
Cluster Requirements
When you create the cluster nodes that make up vRealize Operations Manager, you have general
requirements that you must meet.
General vRealize Operations Manager Cluster Node Requirements
You have to follow some general requirements to create a node on your environment.
General Requirements
nvRealize Operations Manager version. All nodes must run the same vRealize Operations Manager
version.
For example, do not add a version 6.1 data node to a cluster of vRealize Operations Manager 6.2 nodes.
nAnalytics Cluster Deployment Type. In the analytics cluster, all nodes must be the same kind of
deployment: vApp.
nRemote Collector Deployment Type. A remote collector node does not need to be the same deployment
type as the analytics cluster nodes.
When you add a remote collector of a dierent deployment type, the following clusters are supported:
nvApp analytics cluster
nAnalytics Cluster Node Sizing. In the analytics cluster, CPU, memory, and disk size must be identical
for all nodes.
Master, replica, and data nodes must be uniform in sizing.
nRemote Collector Node Sizing. Remote collector nodes may be of dierent sizes from each other or
from the uniform analytics cluster node size.
nGeographical Proximity. You may place analytics cluster nodes in dierent vSphere clusters, but the
nodes must reside in the same geographical location.
Dierent geographical locations are not supported.
nVirtual Machine Maintenance. When any node is a virtual machine, you may only update the virtual
machine software by directly updating the vRealize Operations Manager software.
For example, going outside of vRealize Operations Manager to access vSphere to update VMware Tools
is not supported.
nRedundancy and Isolation. If you expect to enable HA, place analytics cluster nodes on separate hosts.
See About vRealize Operations Manager High Availability,” on page 13.
nYou can deploy remote collectors behind a rewall. You cannot use NAT between remote collectors and
analytics nodes.
Requirements for Solutions
Be aware that solutions might have requirements beyond those for vRealize Operations Manager itself. For
example, vRealize Operations Manager for Horizon View has specic sizing guidelines for its remote
collectors.
See your solution documentation, and verify any additional requirements before installing solutions. Note
that the terms solution, management pack, adapter, and plug-in are used somewhat interchangeably.
vRealize Operations Manager vApp Deployment and Configuration Guide
16 VMware, Inc.
vRealize Operations Manager Cluster Node Networking Requirements
When you create the cluster nodes that make up vRealize Operations Manager, the associated setup within
your network environment is critical to inter-node communication and proper operation.
Networking Requirements
I vRealize Operations Manager analytics cluster nodes need frequent communication with one
another. In general, your underlying vSphere architecture might create conditions where some vSphere
actions aect that communication. Examples include, but are not limited to, vMotions, storage vMotions,
HA events, and DRS events.
nThe master and replica nodes must be use static IP address, or fully qualied domain name (FQDN)
with a static IP address.
Data and remote collector nodes can use dynamic host control protocol (DHCP).
nYou can successfully reverse-DNS all nodes, including remote collectors, to their FQDN, currently the
node hostname.
Nodes deployed by OVF have their hostnames set to the retrieved FQDN by default.
nAll nodes, including remote collectors, must be bidirectionally routable by IP address or FQDN.
nDo not separate analytics cluster nodes with network address translation (NAT), load balancer, rewall,
or a proxy that inhibits bidirectional communication by IP address or FQDN
nAnalytics cluster nodes must not have the same hostname.
nPlace analytics cluster nodes within the same data center and connect them to the same local area
network (LAN).
nPlace analytics cluster nodes on same Layer 2 network and IP subnet.
A stretched Layer 2 or routed Layer 3 network is not supported.
nDo not span the Layer 2 network across sites, which might create network partitions or network
performance issues.
nOne-way latency between the analytics cluster nodes must be 5 ms or lower.
nNetwork bandwidth between the analytics cluster nodes must be one gbps or higher.
nDo not distribute analytics cluster nodes over a wide area network (WAN).
To collect data from a WAN, a remote or separate data center, or a dierent geographic location, use
remote collectors.
nRemote collectors are supported through a routed network but not through NAT.
nDo not include an underscore in the hostname of any cluster node.
vRealize Operations Manager Cluster Node Best Practices
When you create the cluster nodes that make up vRealize Operations Manager, additional best practices
improve performance and reliability in vRealize Operations Manager.
Best Practices
nDeploy vRealize Operations Manager analytics cluster nodes in the same vSphere cluster in a single
datacenter and add only one node at a time to a cluster allowing it to complete before adding another
node.
Chapter 2 Preparing for Installation
VMware, Inc. 17
nIf you deploy analytics cluster nodes in a highly consolidated vSphere cluster, you might need resource
reservations for optimal performance.
Determine whether the virtual to physical CPU ratio is aecting performance by reviewing CPU ready
time and co-stop.
nDeploy analytics cluster nodes on the same type of storage tier.
nTo continue to meet analytics cluster node size and performance requirements, apply storage DRS anti-
anity rules so that nodes are on separate datastores.
nTo prevent unintentional migration of nodes, set storage DRS to manual.
nTo ensure balanced performance from analytics cluster nodes, use ESXi hosts with the same processor
frequencies. Mixed frequencies and physical core counts might aect analytics cluster performance.
nTo avoid a performance decrease, vRealize Operations Manager analytics cluster nodes need
guaranteed resources when running at scale. The vRealize Operations Manager Knowledge Base
includes sizing spreadsheets that calculate resources based on the number of objects and metrics that
you expect to monitor, use of HA, and so on. When sizing, it is beer to over-allocate than under-
allocate resources.
See Knowledge Base article 2093783.
nBecause nodes might change roles, avoid machine names such as Master, Data, Replica, and so on.
Examples of changed roles might include making a data node into a replica for HA, or having a replica
take over the master node role.
nThe NUMA placement is removed in the vRealize Operations Manager 6.3 and later. Procedures related
to NUMA seings from the OVA le follow:

Create a Node by Deploying an OVF
vRealize Operations Manager consists of one or more nodes, in a cluster. To create nodes, you use the
vSphere client to download and deploy the vRealize Operations Manager virtual machine, once for each
cluster node.
Prerequisites
nVerify that you have permissions to deploy OVF templates to the inventory.
nIf the ESXi host is part of a cluster, enable DRS in the cluster. If an ESXi host belongs to a non-DRS
cluster, all resource pool functions are disabled.
nIf this node is to be the master node, reserve a static IP address for the virtual machine, and know the
associated domain name server, default gateway, and network mask values.
Plan to keep the IP address because it is dicult to change the address after installation.
nIf this node is to be a data node that will become the HA replica node, reserve a static IP address for the
virtual machine, and know the associated domain name server, default gateway, and network mask
values.
In addition, familiarize yourself with HA node placement as described in About vRealize Operations
Manager High Availability,” on page 13.
nPreplan your domain and machine naming so that the deployed virtual machine name will begin and
end with alphabet (a–z) or digit (0–9) characters, and will only contain alphabet, digit, or hyphen (-)
characters. The underscore character (_) must not appear in the host name or anywhere in the fully
qualied domain name (FQDN).

nCreate and add data nodes to the unstarted cluster.
nCreate and add remote collector nodes to the unstarted cluster.
nClick Start vRealize Operations Manager to start the single-node cluster, and log in to nish
conguring the product.
The cluster might take from 10 to 30 minutes to start, depending on the size of your cluster and nodes.
Do not make changes or perform any actions on cluster nodes while the cluster is starting.
About the vRealize Operations Manager Master Node
The master node is the required, initial node in your vRealize Operations Manager cluster.
The master node performs administration for the cluster and must be online before you congure any new
nodes. In addition, the master node must be online before other nodes are brought online. If the master node
and replica node go oine together, bring them back online separately. Bring the master node completely
online rst, and then bring the replica node online. For example, if the entire cluster were oine for any
reason, you would bring the master node online rst.
Advantages of a New installation
You can use the new installation to create a new master node during the rst installation of
vRealize Operations Manager. With the master node in place, you can then start adding more nodes to form
a cluster and then dene an environment for your organization.
In a single-node clusters, administration and data are on the same master node. A multiple-node cluster
includes one master node and one or more data nodes. In addition, there might be remote collector nodes,
and there might be one replica node used for high availability. For more information on creating a master
node, see About the vRealize Operations Manager Master Node,” on page 23.

Installing vRealize Operations Manager as an Administrator
As an administrator, you can install several instances of vRealize Operations Manager build in your VM
environment.
Introduction to Express Installation
Express installation is one possible way to create master nodes, add data nodes, form clusters and test your
connection status. You can use express installation to save time and speed up the process of installation
when compared to new installation. It is recommended not to use this feature unless the user is an
administrator.
Figure 33. Express Installation from the Setup screen

You have created a master node to which you can add more nodes.
vRealize Operations Manager vApp Deployment and Configuration Guide
24 VMware, Inc.
Advantages of an Express Installation
Express installation saves time when compared to a new installation to create a new master node. The
express installation uses the default certicates, which diers from one organization to another. This feature
is mainly used by the developers or the administrators.
Expand an Existing Installation of vRealize Operations Manager
Use this option to add a node to an existing vRealize Operations Manager cluster. You can use this option if
you have already congured a master node and you want to increase the capacity by adding more nodes to
your cluster.
Introduction to Expand an Existing Installation
You can deploy and congure additional nodes so that vRealize Operations Manager can support larger
environments. A master node always requires an additional node for a cluster to monitor your environment.
With expanding your installation, you can add more than one node to your cluster.
Adding Data Nodes
Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to
monitor larger environments.
You can dynamically scale out vRealize Operations Manager by adding data nodes without stopping the
vRealize Operations Manager cluster. When you scale out the cluster by 25% or more, you should restart the
cluster to allow vRealize Operations Manager to update its storage size, and you might notice a decrease in
performance until you restart. A maintenance interval provides a good opportunity to restart the
vRealize Operations Manager cluster.
In addition, the product administration options include an option to re-balance the cluster, which can be
done without restarting. Rebalancing adjusts the vRealize Operations Manager workload across the cluster
nodes.
Figure 34. Expand an existing installation from the Setup screen
N Do not shut down online cluster nodes externally or by using any means other than the
vRealize Operations Manager interface. Shut down a node externally only after taking it oine in the
vRealize Operations Manager interface.
Expand an Existing Installation to Add a Data Node
Larger environments with multiple-node vRealize Operations Manager clusters contain one master node
and one or more data nodes for additional data collection, storage, processing, and analysis.

Adding High Availability to vRealize Operations Manager
You can dedicate one vRealize Operations Manager cluster node to serve as a replica node for the
vRealize Operations Manager master node.
Run the Setup Wizard to Add a Master Replica Node
You can convert a vRealize Operations Manager data node to a replica of the master node, which adds high
availability (HA) for vRealize Operations Manager.
N If the cluster is running, enabling HA restarts the cluster.
If you convert a data node that is already in use for data collection and analysis, adapters and data
connections that were provided through that data node fail over to other data nodes.
You may add HA to the vRealize Operations Manager cluster at installation time or after
vRealize Operations Manager is up and running. Adding HA at installation is less intrusive because the
cluster has not yet started.
Prerequisites
nCreate nodes by deploying the vRealize Operations Manager vApp.

vRealize Operations Manager Cluster and Node Maintenance
You perform cluster and node maintenance procedures to help your vRealize Operations Manager perform
more eciently cluster and node maintenance involves activities such as changing the online or oine state
of the cluster or individual nodes, enabling or disabling high availability (HA), reviewing statistics related to
the installed adapters, and rebalancing the workload for beer performance.
You perform most vRealize Operations Manager cluster and node maintenance using the Cluster
Management page in the product interface, or the Cluster Status and Troubleshooting page in the
administration interface. The administration interface provides more options than the product interface.
vRealize Operations Manager vApp Deployment and Configuration Guide
30 VMware, Inc.
Table 41. Cluster and Node Maintenance Procedures
Procedure Interface Description
Change Cluster Status Administration/Product You can change the status of a node to online or
oine.
In a high availability (HA) cluster, taking the
master or replica oine causes
vRealize Operations Manager to run from the
remaining node and for HA status to be degraded.
Any manual or system action that restarts the
cluster brings all vRealize Operations Manager
nodes online, including any nodes that you had
taken oine.
If you take a data node that is part of a multi-node
cluster oine and then bring it back online, the
End Point Operations Management adapter does
not automatically come back online. To bring the
End Point Operations Management adapter
online, select the
End Point Operations Management adapter in the
Inventory Explorer and click the Start Collector
icon .
Enable or Disable High
Availability
Administration Enabling or disabling high availability requires the
cluster to have at least one data node, with all
nodes online or all oine. You cannot use Remote
Collector nodes.
Disabling high availability removes the replica
node and restarts the
vRealize Operations Manager cluster.
After you disable high availability, the replica
node vRealize Operations Manager converts back
to a data node and restarts the cluster.
Generate Passphrase Administration You can generate a passphrase to use instead of
the administrator credentials to add a node to this
cluster.
The passphrase is only valid for a single use.
Remove a Node Administration When you remove a node, you lose data that the
node had collected unless you are running in high
availability (HA) mode. HA protects against the
removal or loss of one node.
You must not re-add nodes to
vRealize Operations Manager that you already
removed. If your environment requires more
nodes, add new nodes instead.
When you perform maintenance and migration
procedures, you should take the node oine, not
remove the node.
Congure NTP Product The nodes in vRealize Operations Manager cluster
synchronize with each other by standardizing on
the master node time or by synchronizing with an
external Network Time Protocol (NTP) source.
Rebalance the Cluster Product You can rebalance adapter, disk, memory, or
network load across vRealize Operations Manager
cluster nodes to increase the eciency of your
environment.

vRealize Operations Manager Post-
Installation Considerations 5
After you install vRealize Operations Manager, there are post-installation tasks that might need your
aention.
This chapter includes the following topics:
nAbout Logging In to vRealize Operations Manager,” on page 35

n“Log in to a Remote vRealize Operations Manager Console Session,” on page 36
nAbout New vRealize Operations Manager Installations,” on page 37
About Logging In to vRealize Operations Manager
Logging in to vRealize Operations Manager requires that you point a Web browser to the fully qualied
domain name (FQDN) or IP address of a node in the vRealize Operations Manager cluster.
When you log in to vRealize Operations Manager, there are a few things to keep in mind.
nAfter initial conguration, the product interface URL is:
hps://node-FQDN-or-IP-address
nBefore initial conguration, the product URL opens the administration interface instead.
nAfter initial conguration, the administration interface URL is:
hps://node-FQDN-or-IP-address/admin
nThe administrator account name is admin. The account name cannot be changed.
nThe admin account is dierent from the root account used to log in to the console, and does not need to
have the same password.
nWhen logged in to the administration interface, avoid taking the node that you are logged into oine
and shuing it down. Otherwise, the interface closes.
nThe number of simultaneous login sessions before a performance decrease depends on factors such as
the number of nodes in the analytics cluster, the size of those nodes, and the load that each user session
expects to put on the system. Heavy users might engage in signicant administrative activity, multiple
simultaneous dashboards, cluster management tasks, and so on. Light users are more common and
often require only one or two dashboards.
The sizing spreadsheet for your version of vRealize Operations Manager contains further detail about
simultaneous login support. See Knowledge Base article 2093783.
nYou cannot log in to a vRealize Operations Manager interface with user accounts that are internal to
vRealize Operations Manager, such as the maintenance Admin account.
VMware, Inc. 35
nYou cannot open the product interface from a remote collector node, but you can open the
administration interface.
nFor supported Web browsers, see the vRealize Operations Manager Release Notes for your version.
Secure the vRealize Operations Manager Console
After you install vRealize Operations Manager, you secure the console of each node in the cluster by logging
in for the rst time.
Procedure
1 Locate the node console in vCenter or by direct access. In vCenter, use Alt+F1 to access the login
prompt.
For security, vRealize Operations Manager remote terminal sessions are disabled by default.
2 Log in as root.
vRealize Operations Manager prevents you from accessing the command prompt until you create a root
password.
3 When prompted for a password, press Enter.
4 When prompted for the old password, press Enter.
5 When prompted for the new password, enter the root password that you want, and note it for future
reference.
6 Re-enter the root password.
7 Log out of the console.
Log in to a Remote vRealize Operations Manager Console Session
As part of managing or maintaining the nodes in your vRealize Operations Manager cluster, you might need
to log in to a vRealize Operations Manager node through a remote console.
For security, remote login is disabled in vRealize Operations Manager by default. To enable remote login,
perform the following steps.

About New vRealize Operations Manager Installations
A new vRealize Operations Manager installation requires that you deploy and congure nodes. Then, you
add solutions for the kinds of objects to monitor and manage.
After you add solutions, you congure them in the product and add monitoring policies that gather the kind
of data that you want.
Log In and Continue with a New Installation
To nish a new vRealize Operations Manager installation, you log in and complete a one-time process to
license the product and congure solutions for the kinds of objects that you want to monitor.
Prerequisites
nCreate the new cluster of vRealize Operations Manager nodes.
nVerify that the cluster has enough capacity to monitor your environment. See “Sizing the vRealize
Operations Manager Cluster,” on page 9.
Procedure
1 In a Web browser, navigate to the IP address or fully qualied domain name of the master node.
2 Enter the username admin and the password that you dened when you congured the master node,
and click Login.
Because this is the rst time you are logging in, the administration interface appears.
3 To start the cluster, click Start vRealize Operations Manager.
4 Click Yes.
The cluster might take from 10 to 30 minutes to start, depending on your environment. Do not make
changes or perform any actions on cluster nodes while the cluster is starting.
5 When the cluster nishes starting and the product login page appears, enter the admin username and
password again, and click Login.
A one-time licensing wizard appears.
6 Click Next.
7 Read and accept the End User License Agreement, and click Next.
8 Enter your product key, or select the option to run vRealize Operations Manager in evaluation mode.
Your level of product license determines what solutions you may install to monitor and manage objects.
nStandard. vCenter only
nAdvanced. vCenter plus other infrastructure solutions
nEnterprise. All solutions
vRealize Operations Manager does not license managed objects in the same way that vSphere does, so
there is no object count when you license the product.
N When you transition to the Standard edition, you no longer have the Advanced and Enterprise
features. After the transition, delete any content that you created in the other versions to ensure that
you comply with EULA and verify the license key which supports the Advanced and Enterprise
features.

Updating, Migrating and Restoring 6
You can update your existing vRealize Operations Manager deployments to a newly released version.
When you perform a software update, you need to make sure you use the correct PAK le for your cluster. A
good practice is to take a snapshot of the cluster before you update the software, but you must remember to
delete the snapshot once the update is complete.
If you have customized the content that vRealize Operations Manager provides such as alerts, symptoms,
recommendations, and policies, and you want to install content updates, clone the content before
performing the update. In this way, you can select the option to reset out-of-the-box content when you
install the software update, and the update can provide new content without overwriting customized
content.
This chapter includes the following topics:
n“Obtain the Software Update PAK File,” on page 39
n“Create a Snapshot as Part of an Update,” on page 40
n“How To Preserve Customized Content,” on page 40
n“Backup and Restore,” on page 41
n“vRealize Operations Manager Software Updates,” on page 41
Obtain the Software Update PAK File
Each type of cluster update requires a specic PAK le. Make sure you are using the correct one.
Download the Correct PAK files
To update your vRealize Operations Manager environment, you need to download the right PAK le for the
clusters you wish to upgrade. Notice that only the Virtual Appliance clusters use an OS Update PAK le.
Host name entries in the /etc/hosts of each node might be reset when applying the OS update PAK le for
an update from vRealize Operations 6.0.x to version 6.1. You can manually update the hosts le after
completing the software update.
Table 61. Specific PAK Files for Different Cluster Types

Create a Snapshot as Part of an Update
It's a good practice to create a snapshot of each node in a cluster before you update a
vRealize Operations Manager cluster. Once the update is complete, you must delete the snapshot to avoid
performance degradation.
For more information about snapshots, see the vSphere Virtual Machine Administration documentation.
Procedure
1 Log into the vRealize Operations Manager Administrator interface at https://<master-node-FQDN-or-
IP-address>/admin.
2 Click Take  under the cluster status.
3 When all nodes are oine, open the vSphere client.
4 Right-click a vRealize Operations Manager virtual machine.
5 Click Snapshot and then click Take Snapshot.
a Name the snapshot. Use a meaningful name such as "Pre-Update."
b Uncheck the Snapshot the Virtual Machine Memory check box.
c Uncheck the Ensure Quiesce Guest File System (Needs VMware Tools installed) check box.
d Click OK.
6 Repeat these steps for each node in the cluster.
What to do next
Start the update process as described in “Install a Software Update,” on page 42.
How To Preserve Customized Content
When you upgrade vRealize Operations Manager, it is important that you upgrade the current versions of
content types that allow you to alert on and monitor the objects in your environment. With upgraded alert
denitions, symptom denitions, and recommendations, you can alert on the various states of objects in
your environment and identify a wider range of problem types. With upgraded views, you can create
dashboards and reports to easily identify and report on problems in your environment.
You might need to perform certain steps before you upgrade the alert denitions, symptom denitions,
recommendations, and views in your vRealize Operations Manager environment.
nIf you customized any of the alert denitions, symptom denitions, recommendations, or views that
were provided with previous versions of vRealize Operations Manager, and you want to retain those
customized versions, perform the steps in this procedure.
nIf you did not customize any of the alert denitions, symptom denitions, recommendations, or views
that were provided with previous versions of vRealize Operations Manager, you do not need to back
them up rst. Instead, you can start the upgrade, and during the upgrade select the check box named
Reset out-of-the-box content.
Prerequisites
You previously customized versions of your alert denitions, symptom denitions, recommendations, or
views.
Procedure
1 Before you begin the upgrade to vRealize Operations Manager, back up the changes to your alert
denitions, symptom denitions, recommendations, and views by cloning them.
vRealize Operations Manager vApp Deployment and Configuration Guide
40 VMware, Inc.
2 Start the upgrade of vRealize Operations Manager.
3 During the upgrade, select the check box named Reset out-of-the-box content.
After the upgrade completes, you have preserved your customized versions of alert denitions, symptom
denitions, recommendations, and views, and you have the current versions that were installed during the
upgrade.
What to do next
Review the changes in the upgraded alert denitions, symptom denitions, recommendations, and views.
Then, determine whether to keep your previously modied versions, or to use the upgraded versions.
Backup and Restore
Backup and restore your vRealize Operations Manager system on a regular basis to avoid downtime and
data loss in case of a system failure. If your system does fail, you can restore the system to the last full or
incremental backup.
You can backup and restore vRealize Operations Manager single or multi-node clusters by using
vSphere Data Protection or other backup tools. You can perform full, dierential, and incremental backups
and restores of virtual machines.
To backup and restore vRealize Suite components by using vSphere Data Protection and NetBackup, see the
Backup and Restore section in the vRealize Suite Information Center.
N All nodes are backed up and restored at the same time. You cannot back up and restore individual
nodes.
vRealize Operations Manager Software Updates
vRealize Operations Manager includes a central page where you can manage updates to the product
software.
How Software Updates Work
The Software Update option lets you install updates to the vRealize Operations Manager product itself.
Where You Find Software Updates
Log in to the vRealize Operations Manager administration interface at hps://master-node-name-or-ip-
address/admin. On the left, click Software Update.
Software Update Options
The options include a wizard for locating the update PAK le and starting the installation, plus a list of
updates and the vRealize Operations Manager cluster nodes on which they are installed.

Install a Software Update
If you have already installed vRealize Operations Manager, you can update your software when a newer
version becomes available.
N Installation might take several minutes or even a couple hours depending on the size and type of
your clusters and nodes.
Prerequisites
nCreate a snapshot of each node in your cluster. For information about how to perform this task, see the
vRealize Operations Manager Information Center.
nObtain the PAK le for your cluster. For information about which le to use, see the
vRealize Operations Manager Information Center.
nBefore you install the PAK le, or upgrade your vRealize Operations Manager instance, clone any
customized content to preserve it. Customized content can include alert denitions, symptom
denitions, recommendations, and views. Then, during the software update, you select the options
named Install the PAK  even if it is already installed and Reset out-of-the-box content.
nThe version 6.2.1 vRealize Operations Manager update operation has a validation process that identies
issues before you start to update your software. Although it is good practice to run the pre-update
check and resolve any issues found, users who have environmental constraints can disable this
validation check.
To disable the pre-update validation check, perform the following steps:
nEdit the update le
to/storage/db/pakRepoLocal/bypass_prechecks_vRealizeOperationsManagerEnterprise-
buildnumberofupdate.json.
nChange the value to TRUE and run the update.
N If you disable the validation, you might encounter blocking failures during the update itself.

Chapter 6 Updating, Migrating and Restoring
VMware, Inc. 43
Migrate a vCenter Operations Manager Deployment into this Version
By importing data, an established or production version of vRealize Operations Manager can assume the
monitoring of a vCenter Operations Manager deployment.
You cannot migrate vCenter Operations Manager directly to this version of vRealize Operations Manager.
Instead, you follow a two-step process:
1 Migrate and import vCenter Operations Manager 5.8.x into vRealize Operations Manager 6.0.x as
described in the version 6.0.x documentation.
2 Use the vRealize Operations Manager Software Update option to update vRealize Operations Manager
6.0.x to this version.
N Make sure your vCenter Operations Manager 5.8.x and vRealize Operations Manager 6.0.x instances
are on the same physical network. Otherwise the data import may not work. Data import process fails when
source (vCenter Operations Manager 5.x) is separated from the destination vRealize Operations Manager 6.x
environment by a slow network connection (WAN). Data import over a connection that is slower than LAN
speed is not supported. For more information, see the Knowledge Base article 2141964.
