Storage Center Updates
Storage Center updates are bundled together as a single downloadable update package. An update package includes the latest
updates for the following storage system components:
• Dell Storage Center operating system software
• Storage Center rmware
• Enclosure rmware
• Disk rmware
Software Update Types
Within a software update package, an individual update component is classied according to the method in which it can be installed.
The method you use to install updates aects your infrastructure dierently.
NOTE: Before applying updates, understand the impact of the update on Storage Center infrastructure and plan the
update process carefully to avoid unplanned downtime.
•Required — Required components must be installed as part of the update.
•Deferrable — Deferrable components can be installed later; however, doing so can negatively aect the reliability of the
components whose rmware is not being updated.
•Service Aecting — Service aecting components can be installed only when Storage Center is temporarily taken out-of-
service. During the outage, all systems and services using volumes from Storage Center must be powered down correctly to
avoid data loss and unplanned system disruption.
•Non-Service Aecting — Non-service aecting components can be installed either when Storage Center is in service or during
a scheduled outage. Although these components are designed to not cause system disruption, the way in which Storage Center
is congured can aect performance. During a non-service aecting update, the rmware update process occurs as a rolling
controller update. This process results in a controller failover event that causes the host initiators to log out and then log back in
to the volumes connected to the SAN. If you have implemented the Dell Storage best practices for host settings (for example,
multipath IO, HBA settings, time-outs) and fabric design (cabling, number of front-end ports), the logout/login process has
minimal eect on host volumes. The update process should not aect data access, data integrity, or result in any data loss.
NOTE: When performing a non-service aecting update, reduce the impact of the controller restart operation on the
host OS and applications by verifying that the correct conguration and best practices are applied to each newly
congured host. Dell recommends that every host that accesses Storage Center volumes or that has large updates
applied to its OS, has at least one failover test.
The following table shows which components aect service during installation.
Table 1. Storage Center with a Single Controller
Service Aecting Non-Service
Aecting
Storage Center Firmware Update Yes
Enclosure Firmware Update. Depending on the components for a specic release,
enclosure rmware may or may not be non-service aecting.
Yes Yes
Disk Firmware Update. Disk rmware upgrades may be service aecting or non-service
aecting depending on the drive. A drive that supports an in-service upgrade, is a
drive that can:
• Process IOs and other commands while receiving rmware blocks.
Yes Yes

aecting depending on the drive. A drive that supports an in-service upgrade, is a
drive that can:
• Process IOs and other commands while receiving rmware blocks.
• Boot and ready new rmware in three seconds.
Yes Yes
Decide How to Apply Updates
Within an update package, an individual update component is classied by the method in which the update component can be
installed. It is critical to know which updates can impact Storage Center operation.
The following list outlines the software update process and the implications to the storage system. For more information, see
Software Update Types.
• The installation process automatically reboots Storage Center storage controller(s) when required by the components being
updated.
• Disk rmware, when applied in-service, does not require a system boot.
• For dual-controller Storage Centers, installation reboots the storage controllers in sequence or simultaneously, depending on the
components being updated. A service outage is required when the storage controllers are rebooted simultaneously.
• To install deferrable components, those that are not required and that do not aect service, plan for applying the updates during
a time at which the Storage Center is least busy.
NOTE: If you do not install deferrable components when you install the required components, it can negatively impact
the reliability of the components whose rmware is not being updated. Dell recommends that you schedule a service
outage and apply deferrable component updates as soon as possible.
• To install components that aect service, plan for and schedule a service outage during which to apply the updates. You may also
want to install components that are non-service aecting during the schedule outage.
CAUTION: Do not manually restart the Storage Center storage controllers during the update process. Updating is a
software-controlled process.
Validate Host Best Practices
To reduce the impact of the controller restart operation on the host operating system and applications when applying non-service
aecting updates, verify that the correct conguration and best practices are applied to the host.
NOTE: Dell recommends that each host has at least one failover test where the redundancy of the HBAs, fabrics, and
storage controllers is tested and validated. Validate every newly congured host that is accessing Storage Center
volumes or when large update packages are applied to the host operating system. See the
Dell Storage Manager
Administrator’s Guide
for more information about HBA server settings and iSCSI settings best practices.
