Common tasks
Upgrading PowerStore appliances
Use PowerStore Manager to upgrade PowerStore OS.
NOTE: The process for upgrading a PowerStore X model appliance has additional steps. See the
PowerStore Virtualization
Guide
for more information about this process.
Upgrade readiness for PowerStore T model appliances
Before initiating an upgrade, review the following considerations:
• You can learn that an upgrade is available in one of the following ways:
• If you are using SupportAssist with your PowerStore appliance, PowerStore Manager notifies you when an upgrade is available.
• If you are not using SupportAssist, or do not have SupportAssist connected to your PowerStore appliance, log in to the support
site and check for an upgrade.
• A few days before upgrading, upload the PowerStore OS image file that you want to install and perform a system health check on it.
The health check ensures that you have time to resolve underlying problems that may prevent a successful upgrade, such as:
• A faulted hardware component
• An incompatible vCenter software version
• There can be up to ten upgrade candidates of different types on the system at a time. However, after an upgrade starts, it must
successfully complete across all appliances in the cluster before another upgrade can be performed.
• You cannot make configuration changes to the system while the upgrade is in progress.
• Applying an upgrade does not stop I/O. The nondisruptive upgrade process uses redundant paths, ensuring that not more than one
node is taken offline at any given time. Either node in your appliance can satisfy I/O requirements.
PowerStore Manager downtime
As a part of the upgrade process, the node that displays PowerStore Manager fails over to the other node. During failover, you are
disconnected from the user interface. Logins are available again after the failover process between nodes completes.
For clusters with exactly two appliances, a second PowerStore Manager disconnect occurs when the second appliance performs its
failover process. This second disconnect during failover does not occur for clusters of three or more appliances.
Upgrading PowerStore T model appliances
For the latest features and improvements, update the appliance software to the latest available version.
Prerequisites
A few days before upgrading, download the latest software version from www.dell.com/support to your management workstation and
perform a system health check on it. See steps 1–4 below. The health check ensures that you have time to resolve underlying problems
that may prevent a successful upgrade.
During a PowerStore T model upgrade where the PowerStore appliance is a VASA provider, you cannot use the vCenter Server to
manage vVol-based VMs on the PowerStore appliance. Management operations such as rebooting VMs, migrating VMs to other ESXi
hosts, and taking VM snapshots cannot be performed during the upgrade. When the PowerStore VASA Provider is offline during the
upgrade, the datastores and VMs on the PowerStore appliance become inaccessible in vCenter Server, but the I/O between the VMs and
the PowerStore appliance continues. After the upgrade is complete, wait until the status of the VASA Provider changes to Online before
performing management operations on the vVol-based VMs.
