Preface As part of an improvement effort, revisions of the software and hardware are periodically released. Some functions that are described in this document are not supported by all versions of the software or hardware currently in use. The product release notes provide the most up-to-date information about product features. Contact your service provider if a product does not function properly or does not function as described in this document.
1 PowerStore software upgrades This document describes how to upgrade the software on your PowerStore cluster. Performing a software upgrade on a PowerStore cluster 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. A single PowerStore appliance node can satisfy I/O requirements. However, you cannot perform configuration changes or management operations on the PowerStore system while the upgrade is in progress.
2 PowerStore T model clusters Topics: • • • • Upgrading PowerStore T model clusters Upgrade readiness for PowerStore T model clusters Perform a PowerStore T model cluster preupgrade Health Check Upgrade the PowerStore T model software Upgrading PowerStore T model clusters For the latest features and improvements, upgrade the software on the PowerStore T model cluster to the latest available version.
○ Wait until all the cluster nodes have been rebooted before performing a software upgrade. CAUTION: The software upgrade fails if the nodes on a PowerStore T model cluster with NAS enabled are not rebooted after changes are made to CHAP settings. For instructions on rebooting PowerStore T model nodes, see the PowerStore Power Down and Reboot Procedures Guide.
The PowerStore T model software upgrade takes approximately one hour to one and a half hours to complete per appliance. The amount of time that the software upgrade depends on whether node firmware upgrades are applied during the upgrade. Results During the software upgrade process, the primary node of the primary appliance fails over to the peer node of the appliance and you are disconnected from PowerStore Manager. You can log back in to PowerStore Manager after the failover process is complete.
3 PowerStore X model clusters Topics: • • • • • • • Upgrading PowerStore X model clusters Upgrade readiness for PowerStore X model clusters Perform a PowerStore X model cluster preupgrade Health Check Install the PowerStore X model preupgrade package Install the PowerStore X model node firmware upgrade Update the PowerStore internal ESXi hosts Upgrade the PowerStore OS Upgrading PowerStore X model clusters For the latest features and improvements, upgrade the software on the PowerStore X model cluster to
When the PowerStore X model software upgrade package finishes uploading, it is displayed in the Software packages table. d. Repeat the previous two steps to upload all the PowerStore X model software upgrade packages to the PowerStore X model cluster. 4. If an ESXi update is available or required, import the ESXi update package to vSphere Update Manager or vSphere Lifecycle Manager. a. In PowerStore Manager, select Compute > vCenter Server Connection and select Launch vSphere to start the vSphere Client. b.
● Migrate the user VMs to other available ESXi hosts. ● Power off the user VMs on the ESXi host. NOTE: Any VMs that are migrated as a part of the software upgrade process are not automatically migrated back to their original location after the upgrade is complete. Minimizing internal ESXi host failover occurrences Updating an ESXi host on the internal node of a PowerStore X model cluster requires placing the ESXI host into maintenance mode.
NOTE: A Health Check must be performed before installing the preupgrade package, installing the firmware upgrade package, and upgrading the PowerStore OS. 4. Review the overall health state for each node in the cluster. Review the error or warning messages that were generated during the Health Check and address each error or warning accordingly. If you require assistance addressing the error or warning messages, contact your service provider for assistance.
Install the PowerStore X model node firmware upgrade Use PowerStore Manager to install the node firmware upgrade package on a PowerStore X model cluster. Prerequisites Ensure that a preupgrade Health Check has been performed at least seven days before installing the node firmware package on the PowerStore X model cluster. For instructions, see Perform a PowerStore X model cluster preupgrade Health Check on page 11.
Steps 1. Identify the primary and peer nodes on the primary appliance of the cluster. See Minimizing internal ESXi host failover occurrences on page 11 for more information. 2. Select Compute > vCenter Server Connection and select Launch vSphere to start the vSphere Client. 3. In the vSphere Client, log in to the vCenter Server and open vSphere Update Manager or vSphere Lifecycle Manager. 4. Create a baseline for the update using the Patch content type. a.
Upgrade the PowerStore OS Use PowerStore Manager to perform a PowerStore OS upgrade. Prerequisites Ensure that a preupgrade Health Check has been performed at least seven days before upgrading the PowerStore OS on the PowerStore X model cluster. For instructions, see Perform a PowerStore X model cluster preupgrade Health Check on page 11.
