Upgrade the software, drive firmware, or Language pack on your
PowerStore cluster.
This document describes the process for upgrading
PowerStore X. For instructions on upgrading
PowerStore T, see the
PowerStore T model Software Upgrade Guide.
General upgrade considerations
Before preparing for an upgrade, review the following considerations:
NOTE: Not all
PowerStoreOS versions can be directly upgraded to the latest
PowerStoreOS version. For the latest information on supported upgrade paths for your model, see
KB article 000175213
PowerStoreOS Matrix.
Performing a non-disruptive upgrade (NDU) on a
PowerStore cluster does not stop I/O. The I/O requirements of the
PowerStore cluster can be met by a single node on each appliance in the cluster. The NDU process ensures that only one node of the cluster is taken offline at any given time. Taking a node offline does not cause host I/O disruptions when the hosts have redundant data access paths present and the best practices are configured for the host operating system.
During the NDU, you cannot perform configuration changes or management operations on the
PowerStore cluster.
When the
PowerStoreOS is upgraded and the
PowerStore VASA provider is offline, the I/O and availability of the vVol-based VMs served from the
PowerStore cluster are not impacted. However, management operations such as creating VMs, rebooting VMs, migrating VMs to other ESXi hosts, and taking VM snapshots cannot be performed on vVol-based VMs while the VASA provider is offline.
Check the
PowerStore Simple Support Matrix to ensure your host HBA driver and firmware are supported.
PowerStore NDU is supported with Solaris native MPxIO starting at Solaris 11.4 SRU 35. Contact your service provider for
PowerStore NDU support on earlier Solaris versions or Solaris updates.
When the
PowerStoreOS upgrade is complete, wait five to ten minutes for the status of the
PowerStore VASA provider to change to Online in vCenter Server before creating storage containers or performing management operations on vVol-based VMs.
NOTE: Within this document,
PowerStore software refers to the software upgrade package for a
PowerStore system and
PowerStoreOS is the operating system that runs on the nodes of a
PowerStore cluster.
