Metric Definitions in
vRealize Operations Manager

Metric definitions provide an overview of how the metric value is calculated or derived. If you understand
the metric, you can better tune vRealize Operations Manager to display results that help you to manage
your environment.
vRealize Operations Manager collects data from objects in your environment. Each piece of data collected is
®
called a metric observation or value. vRealize Operations Manager uses the VMware vCenter adapter to
collect raw metrics. vRealize Operations Manager uses the vRealize Operations Manager adapter to collect
self-monitoring metrics. In addition to the metrics it collects, vRealize Operations Manager calculates
capacity metrics, badge metrics, and metrics to monitor the health of your system.
All metric definitions are provided. The metrics reported on your system depend on the objects in your
environment. You can use metrics to help troubleshoot problems. See the vRealize Operations Manager User
Guide.

Changes in Metric Availability
The CPU Demand of Recommended (%) metric is no longer available in vRealize Operations Manager
version 6.x. To approximate the metric, create a super metric using the following calculations, and add it to
your Views and Reports as needed.
( (CPU|Stress Free Demand (MHz)) × (CPU|Current Size in Unit(s)) ) ÷ ( (CPU|Recommended Size
(vCPUs)) × (CPU|Current Size (MHz)) )

For more information about super metrics, see the vRealize Operations Manager Information Center.

Metrics for vCenter Server Components
®

vRealize Operations Manager connects to VMware vCenter Server instances through the vCenter adapter
to collect metrics for vCenter Server components and uses formulas to derive statistics from those metrics.
You can use metrics to troubleshoot problems in your environment.
vCenter Server components are listed in the describe.xml file for the vCenter adapter. The following
example shows sensor metrics for the host system in the describe.xml file.

Each ResourceAttribute element includes the name of a metric that appears in the UI and is documented as
a Metric Key.
Table 1‑1. Sensor Metrics for Host System Cooling
Metric Key

Metric Name

Description

Sensor|fan|currentValue

Speed

vSphere Metrics
vRealize Operations Manager collects CPU use, disk, memory, network, and summary metrics for objects in
the vSphere world.
Capacity metrics can be calculated for vSphere world objects. See “Capacity and Project-Based Metrics,” on
page 77.

CPU Usage Metrics
CPU usage metrics provide information about CPU use.

VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Table 1‑2. CPU Usage Metrics
Metric Name

Description

CPU|Capacity usage

CPU usages as a percent during the interval.
Key: cpu|capacity_usagepct_average

CPU|CPU contention(%)

This metric shows the percentage of time the VMs in the ESXi hosts are
unable to run because they are contending for access to the physical CPUs.
The number shown is the average number for all VMs. The number will be
lower than the highest number experienced by the VM that is most impacted
by CPU contention.
Use this metric to verify if the host can serve all its VMs efficiently. Low
contention means that the VM can access everything it demands to run
smoothly. It means that the infrastructure is providing good service to the
application team.
When using this metric, ensure that the number is within your expectation.
Look at both the relative number and the absolute number. Relative means a
drastic change in value, meaning that the ESXi is unable to serve the VMs.
Absolute means that the real value itself is high. Investigate why the number
is high. One factor that impacts this metric is CPU Power Management. If
CPU Power Management clocks down the CPU speed from 3 GHz to 2 GHz,
the reduction in speed is accounted for because it shows that the VM is not
running at full speed.
This metric is calculated in the following way: cpu|capacity_contention / (200
* summary|number_running_vcpus)
Key: cpu|capacity_contentionPct

CPU|Demand (%)

This metric shows the amount of CPU resources a virtual machine would use
if there were no CPU contention or CPU limit. This metric represents the
average active CPU load for the past five minutes.
Keep this number below 100% if you set the power management to
maximum.
This metric is calculated in the following way: ( cpu.demandmhz /
cpu.capacity_provisioned)*100
Key: cpu|demandPct

CPU|Demand (MHz)

This metric shows the amount of CPU resources a virtual machine would use
if there were no CPU contention or CPU limit.
Key: cpu|demandmhz

Table 1‑2. CPU Usage Metrics (Continued)
Metric Name

Description

CPU|Usage (MHz)

CPU usages, as measured in megahertz, during the interval.
n VM - Amount of actively used virtual CPU. This is the host's view of the
CPU usage, not the guest operating system view.
n Host - Sum of the actively used CPU of all powered on virtual machines
on a host. The maximum possible value is the frequency of the two
processors multiplied by the number of processors. For example, if you
have a host with four 2 GHz CPUs running a virtual machine that is
using 4000 MHz, the host is using two CPUs completely: 400 / (4 2000) =
0.50
Key: cpu|usagemhz_average

CPU|Wait

Total CPU time spent in wait state. The wait total includes time spent in the
CPU Idle, CPU Swap Wait, and CPU I/O Wait states.
Key:cpu|wait

CPU|Workload (%)

Table 1‑3. Memory Metrics
Metric Name

Description

mem|Contention (%)

This metric shows the percentage of time VMs are waiting to access swapped
memory.
Use this metric to monitor ESXi memory swapping. A high value indicates
that the ESXi is running low on memory, and a large amount of memory is
being swapped.
Key: mem|host_contentionPct

mem|Machine Demand (KB)

Host memory demand in kilobytes.
Key: mem|host_demand

mem|Provisioned Memory

Provisioned host memory in kilobytes.
Key: mem|host_provisioned

mem|Usable Memory (KB)

Usable host memory in kilobytes.
Key: mem|host_usable

mem|Host Usage (KB)

Host memory use in kilobytes.
Key: mem|host_usage

mem|Usage/Usable (%)

Memory usage as percentage of total configured or available memory.
Key: mem|host_usagePct

mem|Workload (%)

Percent of workload.
Key: mem|workload

Network Metrics
Network metrics provide information about network performance.

VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Table 1‑4. Network Metrics
Metric Name

Description

net|Packets Dropped (%)

This metric shoes the percentage of received and transmitted packets
dropped in the collection interval.
Use this metric to monitor the reliability and performance of the ESXi
network. A high value indicates that the network is not reliable and
performance decreases.
Key: net|droppedPct

net|Usage Rate (KB per second)

Sum of the data transmitted and received for all of the NIC instances of the
host or virtual machine.
Key: net|usage_average

Average of the sum of the data read and written for all of the disk instances
of the host or virtual machine.
Key: disk|usage_average

disk|Workload (%)

Percent of workload.
Key: disk|workload

Summary Metrics
Summary metrics provide information about overall performance.
Table 1‑6. Summary Metrics
Metric Name

Description

summary|Number of Running Hosts

Number of running hosts.
Key: summary|number_running_hosts

summary|Number of Running VMs

This metric shows the number of running VMs at a given point in time.
The data is sampled every five minutes.
A large number of running VMs might be a reason for CPU or memory
spikes because more resources are used in the host. The number of
running VMs gives you a good indicator of how many requests the ESXi
host must juggle. Powered off VMs are not included because they do not
impact ESXi performance. A change in the number of running VMs can
contribute to performance problems. A high number of running VMs in
a host also means a higher concentration risk, because all the VMs will
fail if the ESXi crashes.
Use this metric to look for a correlation between spikes in the running
VMs and spikes in other metrics such as CPU contention, or memory
contention.
Key: summary|number_running_vms

summary|Total Number of Clusters

Total number of clusters.
Key: summary|total_number_clusters

Metric

Description

CPU|Capacity Usage (%)

Percent CPU capacity used.
Key: cpu|capacity_usagepct_average

CPU|Usage (%)

Average CPU usage as a percentage.
Key: cpu|usage_average

* CPU|CPU Contention (%)

This metric indicates the percentage of time the virtual
machines in the ESXi hosts are unable to run because they are
contending for access to the physical CPU(s). This is the
average number of all VMs. Naturally, the number will be
lower than the highest number experienced by the worst hit
VM (a VM that suffers the highest CPU contention).
Use this metric to verify if the host is able to serve all of its
VMs well.
When using this metric, ensure the number is within your
expectation. The metric is affected by several factors so you
need to watch both relative numbers and absolute numbers.
Relative means a drastic change in value. This indicates that
the ESXi is unable to service its VMs.
Absolute means that the real value is high. You should
investigate why the value is high. One factor that impacts the
CPU contention metric is CPU Power Management. If CPU
Power Management clocks down the CPU speed from 3 GHz
to 2 GHz that reduction in speed is taken into account. This is
because the VM is not running at full speed.
Key: cpu|capacity_contentionPct

* CPU|Demand (%)

This metric shows the percentage of CPU resources all the
VMs would use if there was no CPU contention or any CPU
limits set.
It represents the average active CPU load for the past five
minutes.

* Mem|Balloon (KB)

This metric shows the total amount of memory
currently used by the VM memory control. This
memory was reclaimed from the respective VMs at
some point in the past, and was not returned.
Use this metric to monitor how much VM memory
has been reclaimed by ESXi through memory
ballooning.
The presence of ballooning indicates the ESXi has
been under memory pressure. The ESXi activates
ballooning when consumed memory reaches a certain
threshold.
Look for increasing size of ballooning. This indicates
that there has been a shortage of memory more than
once. Look for size fluctuations which indicate the
ballooned out page was actually required by the VM.
This translates into a memory performance problem
for the VM requesting the page, since the page must
first be brought back from the disk.

Summary Metrics for Host Systems
Summary metrics provide information about overall host system performance.

VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Metric

Description

* Summary|Number of Running VMs

This metric shows the number of VMs running on the host
during the last metric collection time.
Large spikes of running VMs might be a reason for CPU or
memory spikes as more resources will be used in the host.
Number of Running VMs gives you a good indicator of how
many requests the ESXi host must juggle. This excludes
powered off VMs as they do not impact ESXi performance. A
change in this number in your environment can contribute to
performance problems. A high number of running VMs in a
host also means a higher concentration risk, as all the VMs
will go down (or be relocated by HA) if the ESXi crashes.
Look for any correlation between spikes in the number of
running VMs and spikes in other metrics such as CPU
Contention/Memory Contention.
Key: summary|number_running_vms

Summary|Maximum Number of VMs

Key: summary|max_number_vms

* Summary|Number of vMotions

This metric shows the number of vMotions that occurred in

The number of vMotions is a good indicator of stability. In a
healthy environment, this number should be stable and
relatively low.
Look for correlation between vMotions and spikes in other
metrics such as CPU/Memory contention.
The vMotion should not create any spikes, however, the VMs
moved into the host might create spikes in memory usage,
contention and CPU demand and contention.

CPU Usage Metrics for Cluster Compute Resources
CPU usage metrics provide information about CPU use.
Metric

Description

CPU|Capacity Usage

This metric shows the percentage of the capacity used.
Key: cpu|capacity_usagepct_average

* CPU|CPU Contention (%)

This metric is an indicator of the overall contention for CPU
resources that occurs across the workloads in the cluster. When
contention occurs, it means that some of the virtual machines are
not immediately getting the CPU resources they are requesting.
Use this metric to identify when a lack of CPU resources might be
causing performance issues in the cluster.
This metric is the sum of the CPU contention across all hosts in the
cluster averaged over two times the number of physical CPUs in the
cluster to account for hyper-threading. CPU contention takes into
account:
n CPU Ready
n CPU Co-stop
n Power management
n Hyper threading
This metric is more accurate than CPU Ready since it takes into
account CPU Co-stop and Hyper threading.
When using this metric, the number should be lower than the
performance you expect. If you expect performance at 10%, then the
number should be lower than 10%.
Since this value is averaged across all hosts in the cluster, you may
find that some hosts have a higher CPU contention while others are
lower. In order to ensure that vSphere spreads out the running
workloads across hosts, consider enabling a fully-automated DRS in
the cluster.
Key: cpu|capacity_contentionPct

* CPU|Demand (%)

This metric is an indicator of the overall demand for CPU resources
by the workloads in the cluster.
It shows the percentage of CPU resources that all the virtual
machines would use if there were no CPU contention or CPU limits
set. It represents the average active CPU load in the past five
minutes.

Datastore Metrics
vRealize Operations Manager collects capacity, device, and summary metrics for datastore objects.
Capacity metrics can be calculated for datastore objects. See “Capacity and Project-Based Metrics,” on
page 77.
Metrics marked with an asterisk (*) provide the most relevant data to use when you troubleshoot the
datastores in your environment.

Capacity Metrics for Datastores
Capacity metrics provide information about datastore capacity.

Metric

Description

* Capacity|Available Space (GB)

This metric shows the amount of free space that a datastore has
available.
Use this metric to know how much storage space is unused on
the datastore. Try to avoid having too little free disk space in
order to accommodate unexpected storage growth on the
datastore. The exact size of the datastore is based on company
policy.
Key: capacity|available_space

Capacity|Data Store Capacity Contention

Datastore capacity contention.
Key: capacity|contention

* Capacity|Provisioned (GB)

This metric shows the amount of storage that was allocated to
the virtual machines.
Use this metric to know how much storage space is currently
being used on the datastore.
Check the metric trend to identify spikes or abnormal growth.
Key: capacity|provisioned

* Capacity|Total Capacity (GB)

This metric shows the overall size of the datastore.
Use this metric to know the total capacity of the datastore.
Typically the size of the datastore should not be too small. VMFS
datastore size has grown over the years as virtualization matures
and larger vitual machines are now onboard. Ensure the size can
handle enough virtual machines to avoid datastore sprawl. A
best practise is to use 5 TB for VMFS and more for vSAN.
Key: capacity|total_capacity

Capacity|Used Space (GB)

This metric shows the amount of storage that is being used on
the datastore.
Key: capacity|used_space

Capacity|Workload (%)

Key: capacity|consumer_provisioned

* Capacity|Used Space (%)

This metric shows the amount of storage that is being used on
the datastore.
Use this metric to know the percentage of storage space being
used on the datastore.
When using this metric, verify that you have at least 20% of free
storage. Less than this, and you may experience problems when
a snapshot is not deleted. If you have more than 50% free storage
space, you are not utilizing your storage in the best possible way.

VMware, Inc.

Chapter 1 Metric Definitions in vRealize Operations Manager

Metric

Description

* Datastore|Disk Command Latency (ms)

This metric shows the adjusted read and write latency
at the datastore level. Adjusted means that the latency
is taking into account the number of IOs. If your IO is
read-dominated, the combined value is influenced by
the reads.
This is the average of all the VMs running in the
datastore. Because it is an average, some VMs logically
experience higher latency that the value shown by this
metric. To see the worst latency experienced by any
VM, use the Maximum VM Disk Latency metric.
Use this metric to see the performance of the datastore.
It is one of two key performance indicators for a
datastore, the other being the Max Read Latency. The
combination of Maximum and Average gives better
insight into how well the datastore is coping with the
demand.
The number should be lower than the performance you
expect.

* Datastore|Reads per second (IOPS)

This metric displays the average number of read
commands issued per second during the collection
interval.
Use this metric when the total IOPS is higher than
expected. Drill down to see if the metric is read or write
dominated. This helps determine the cause of the high
IOPS. Certain workloads such as backups, anti-virus
scans, and Windows updates carry a Read/Write
pattern. For example, an anti-virus scan is heavy on
read since it is mostly reading the file system.

About Datastore Metrics for Virtual SAN
The metric named datastore|oio|workload is not supported on Virtual SAN datastores. This metric
depends on datastore|demand_oio, which is supported for Virtual SAN datastores.
The metric named datastore|demand_oio also depends on several other metrics for Virtual SAN datastores,
one of which is not supported.
n

The metrics named devices|numberReadAveraged_average and devices|numberWriteAveraged_average
are supported.

The metric named devices|totalLatency_average is not supported.

As a result, vRealize Operations Manager does not collect the metric named datastore|oio|workload for
Virtual SAN datastores.

* Diskspace|Snapshot Space (GB)

This metric shows the amount of space taken by snapshots
on a given database.
Use this metric to know how much storage space is being
used by virtual machine snapshots on the datastore.
Check that the snapshot is using 0 GB or minimal space.
Anything over 1 GB should trigger a warning. The actual
value depends on how IO intensive the virtual machines in
the datastore are. Run a DT on them to detect anomaly.
Clear the snapshot within 24 hours, preferably as soon as
you have finished backing up, or patching.

Summary Metrics for Datastores
Summary metrics provide information about overall performance.
Metric

Description

* Summary|Total Number of Hosts

This metric shows the number of hosts that the datastore is
connected to.
Use this metric to know how many clusters the datastore is
attached to.
The number should not be too high, as a datastore should
not be mounted by every host. The datastore and cluster
should be paired to keep operations simple.
Key: summary|total_number_hosts

* Summary|Total Number of VMs

This metric shows the number of virtual machines which
save their VMDK files on the datastore. If a VM has four
VMDKs stored in four datastores, the VM will be counted
on each datastore.
Use this metric to know how many VMs have at least one
VMDK on a specific datastore.
The number of VMs should be within your Concentration
Risk policy.
You should also expect the datastore to be well used. If only
a few VMs are using the datastore, this is not considered a
good use.

Calculated Metrics
vRealize Operations Manager calculates metrics for capacity, badges, and the health of the system.
Calculated metrics apply to a subset of objects found in the describe.xml file that describes each adapter.
From data that the vCenter adapter collects, vRealize Operations Manager calculates metrics for objects of
type:

Capacity and Project-Based Metrics
The capacity engine computes and publishes metrics that help you to plan your resource use based on
consumer demand. Project-based metrics are a subset of capacity metrics that help to plan future resource
use based on predicted consumer demand.

Capacity Metrics Group
For the capacity metrics group, full metric names include the name of the resource container. For example, if
density metrics are computed for CPU or memory, the actual metric names appear as cpu|density or mem|
density.
Only resource containers enabled for the capacity computations have relevant metrics. Not all metric types
are generated for all resource containers. For example, if CPU or memory resource containers are enabled in
a policy for density, but the network resource container is not, then cpu|density and mem|density metrics
are calculated but network|density metrics are not.
A capacity metric definition includes resource containers that act as a consumer or a provider. For example
in vSphere, the virtual machines are consumers of CPU and memory that the ESX host provides.

Project-Based Metrics
Project-based metrics are calculated for a change in resources or demand that could affect capacity at some
time in the future. See vRealize Operations Manager User Guide. Most metrics appear with_whatif appended
to the capacity metric name. For example, the what-if applicable metric for capacity remaining is published
as capacityRemaining_whatif.

Badge Metrics
Badge metrics provide information for badges in the user interface. They report the health, risk, and
efficiency of objects in your environment.
vRealize Operations Manager 6.x analyzes badge metric data at five-minute averages, instead of hourly. As a
result, you might find that efficiency and risk badge calculations are more sensitive than in previous
versions. Badge metrics continue to be published nightly.

Managed Resources Object as a Filter in vRealize Automation
The vRealize Automation solution uses filters to display the VMware vCenter adapter objects that are
managed by or have some association with vRealize Automation. Some of the dashboards have widgets that
are configured to display only VMware vCenter adapter objects that vRealize Automation manages or is
associated with. vRealize Automation uses an object called Managed Resources as a filter to display only
those objects. All of these resources are placed under the Managed Resources object of type
vRealize Automation Entity Status. The absence of this filter causes all VMware vCenter adapter objects to
be displayed in the widgets. If you delete the Managed Resources object, the adapter re-creates the object,
but the dashboards display incorrect information in the widgets that use this filter. If you delete the
Managed Resources object, you must manually configure the widgets in the dashboard and select the
Managed Resources object as a filter in each section that displays the VMware vCenter adapter objects.

Metrics for vSAN

Metrics for the Operating Systems and Remote Service Monitoring
Plug-ins in End Point Operations Management
vRealize Operations Manager collects metrics for the object types in the Operating Systems and Remote
Service Monitoring plug-ins.
Due to rounding in metric time calculation, there can be situations in which the Resource Availability metric
is rounded up. Rounding up the metric appears as gaps in the metrics reported by the
End Point Operations Management agent. However, the metrics are fully reported.

Operating Systems Plug-in Metrics
The Operating Systems plug-in collects metrics for object types such Linux, AIX, Solaris, and Windows. The
Operating Systems plug-in also collects metrics for Windows services, Script services, and Multiprocess
services.

AIX Metrics
The Operating Systems Plug-in discovers the metrics for the AIX object type. AIX 6.1 and 7.1 are supported.

If you stop an End Point Operations Management agent by using Windows Services, and remove the data
directory from inside the agent installation directory, when you start the agent again, using Windows
Services, no metrics are collected. If you are deleting the data directory, do not use Windows Services to stop
and start an End Point Operations Management agent. Stop the agent using epops-agent.bat stop. Delete
the data directory, then start the agent using epops-agent.bat start.

Property Definitions in vRealize
Operations Manager

Properties are attributes of objects in the vRealize Operations Manager environment. You use properties in
symptom definitions. You can also use properties in dashboards, views, and reports.
vRealize Operations Manager uses adapters to collect properties for target objects in your environment.
Property definitions for all objects connected through the vCenter adapter are provided. The properties
collected depend on the objects in your environment.
You can add symptoms based on properties to an alert definition so that you are notified if a change occurs
to properties on your monitored objects. For example, disk space is a hardware property of a virtual
machine. You can use disk space to define a symptom that warns you when the value falls below a certain
numeric value. See the vRealize Operations Manager User Guide.
vRealize Operations Manager generates Object Type Classification and Subclassification properties for every
object. You can use object type classification properties to identify whether an object is an adapter instance,
custom group, application, tier, or a general object with property values ADAPTER_INSTANCE, GROUP,
BUSINESS_SERVICE, TIER, or GENERAL, respectively.
This chapter includes the following topics:
n

“Properties for vCenter Server Components,” on page 131

“Self-Monitoring Properties for vRealize Operations Manager,” on page 144

“Properties for vSAN,” on page 146

Properties for vCenter Server Components
The VMware vSphere solution is installed with vRealize Operations Managerand includes the vCenter
adapter. vRealize Operations Manager uses the vCenter adapter to collect properties for objects in the
vCenter Server system.
vCenter Server components are listed in the describe.xml file for the vCenter adapter. The following
example shows the runtime property memoryCap or Memory Capacity for the virtual machine in the
describe.xml.

The ResourceAttribute element includes the name of the property that appears in the UI and is documented
as a Property Key. isProperty = "true" indicates that ResourceAttribute is a property.

vSphere HA failover resources are

vSphere HA failover resources are
insufficient (fault symptom)

To resolve this problem, use similar
CPU and memory reservations for all
virtual machines in the cluster. If this
solution is not possible, consider using
a different vSphere HA admission
control policy, such as reserving a
percentage of cluster resource for
failover. Alternatively, you can use
advanced options to specify a cap for
the slot size. For more information, see
the vSphere Availability Guide. Hosts
that have vSphere HA agent errors are
not good candidates for providing
failover capacity in the cluster and
their resources are not considered for
vSphere HA admission control
purposes. If many hosts have a
vSphere HA agent error, vCenter
Server generates this event leading to
the fault. To resolve vSphere HA agent
errors, check the event logs for the
hosts to determine the cause of the
errors. After you resolve any
configuration problems, reconfigure
vSphere HA on the affected hosts or on
the cluster.

The host has lost redundant
connectivity to a dvPort.

Lost network redundancy to DVPorts
(fault symptom).

Replace the physical adapter or reset
the physical switch. The alert will be
canceled when connectivity is restored
to the DVPort.

The host has lost redundant uplinks to
the network.

Lost network redundancy (fault
symptom).

To determine the actual failure or to
eliminate possible problems, first
connect to ESX through SSH or the
console:
1 Identify the available uplinks by
running esxcfg-nics -l.
2 Remove the reported vmnic from
the port groups by running
esxcfg-vswitch -U
<affected vmnic#>
affected vSwitch.
3 Link available uplinks to the
affected port groups by running
esxcfg-vswitch -L
<available vmnic#>
affected vSwitch.
Next, check the status of the vmnic in
vSphere Client or the ESX service
console:
1 In vSphere Client, select the ESX
host, click Configuration, and then
click Networking.
The vmnics currently assigned to
virtual switches appear in the
diagrams. If a vmnic displays a red
X, that link is currently
unavailable.
2 From the service console, run
esxcfg-nics -l. The output that
appears is similar to the following
example: Name PCI Driver Link

Up 1000Mbps Full Broadcom
BCM5780 Gigabit Ethernet. The Link
column shows the status of the link
between the network adapter and the
physical switch. The status can be
either Up or Down. If some network
adapters are up and others are down,
you might need to verify that the
adapters are connected to the intended
physical switch ports. To verify the
connections, shut down each ESX host
port on the physical switch, run the
"esxcfg-nics -l" command, and observe
the affected vmnics. Verify that the
vmnic identified in the alert is still
connected to the switch and
configured properly:
1 Make sure that the network cable
is still connected to the switch and
to the host.

Determine whether the connectivity
issue is with the iSCSI storage or the
fiber storage.
Troubleshoot the connectivity to the
iSCSI storage by using the software
initiator:
1 Check whether a ping to the
storage array fails from ESX. For
more information, see

Ethernet switch, Ethernet cables
between the switch and the ESX
host, and Ethernet cables between
