NOTE:
Within this document, PowerStore software is the software upgrade package for a PowerStore system and
PowerStore OS is the operating system that runs on the nodes of a PowerStore appliance.
Upgrading PowerStore T model appliances
For the latest features and improvements, update the PowerStore T model appliance software to the latest available version.
During a PowerStore T model software upgrade, management operations on vVol-based VMs served from the PowerStore
cluster cannot be performed because the PowerStore VASA provider temporarily goes offline when the PowerStore OS is
upgraded. The I/O and availability of the vVol-based VMs is not impacted. However, management operations such as creating
VMs, rebooting VMs, migrating VMs to other ESXi hosts, and taking VM snapshots cannot be performed during a PowerStore
software upgrade.
NOTE:
After the upgrade is complete, wait five to ten minutes for the status of the VASA Provider to change to Online
before creating storage containers or performing management operations on vVol-based VMs.
Upgrade readiness for PowerStore T model appliances
Before upgrading, review the following considerations:
●
You can learn that an upgrade is available in one of the following ways:
○
If you are using SupportAssist on your PowerStore cluster, PowerStore Manager notifies you when an upgrade is
available.
○
If you are not using SupportAssist, or it is not enabled on your PowerStore cluster, access the Dell Digital Locker at
and check for an upgrade.
●
A few days before upgrading, upload the PowerStore software upgrade package that you want to install on your PowerStore
cluster and perform a system health check on it. The health check ensures that there are no underlying problems that may
prevent a successful upgrade, such as:
○
A faulted hardware component
○
An incompatible vCenter software version
●
You can upload up to ten upgrade packages on your PowerStore cluster at one time. However, after an upgrade starts, it
must be successfully completed 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.
●
Performing an upgrade on a PowerStore T model appliance does not stop I/O. The nondisruptive upgrade process uses
redundant paths, ensuring that no 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 peer node. During the failover,
you are disconnected from PowerStore Manager. You can log back in to PowerStore Manager after the failover process is
complete.
