Dell EMC PowerStore Software Upgrade Guide

This document describes how to upgrade the software on your PowerStore cluster.

Topics:

• Upgrading PowerStore T model clusters

• Upgrading PowerStore X model appliances

• Additional Resources

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.

Similarly, when the PowerStore OS 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.

When the PowerStore OS 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 is the software upgrade package for a PowerStore system and

PowerStore OS is the operating system that runs on the nodes of a PowerStore cluster.

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.

About this task

When upgrading a PowerStore T model cluster, use only Dell EMC qualified software that is downloaded from the Dell Digital

Locker. The PowerStore T model upgrade package is single file that contains firmware upgrades and the PowerStore OS

upgrade.

Steps

1. Review the upgrade considerations in Upgrade readiness for PowerStore T model clusters on page 2.

2. Download the latest PowerStore T model software upgrade package from the Dell Digital Locker as described in the

Installation and Upgrade Considerations section of the PowerStore Release Notes.

3. Perform a Health Check on the PowerStore T model cluster at least seven days before performing the upgrade.

For instructions, see Perform a PowerStore T model cluster preupgrade Health Check on page 2.

4. Perform the steps in Upgrade the PowerStore T model software on page 2.

The PowerStore T model software upgrade takes approximately one hour to one and a half hours to complete per appliance.

Results

If the software upgrade process is successful, the software on the PowerStore T model cluster is upgraded. If the software

upgrade process fails, check for and resolve all critical alerts on the cluster and retry the upgrade.

Steps 1. Open PowerStore Manager. 2. Select the Settings icon, and then select Upgrades in the Cluster section. 3. If the PowerStore T model software upgrade package has not been uploaded to PowerStore Manager: a. Select Upload Package. The Choose File to Upload dialog box is displayed. b. Select the PowerStore T model software upgrade package, and select Open. The PowerStore T model software upgrade package is uploaded to PowerStore Manager and displayed in the Software packages table.

b. Select Upload Package. c. Select the PowerStore X model software upgrade package to upload and select Open. NOTE: Do not close or refresh the browser while the software upgrade package is uploaded to PowerStore Manager. 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 appliance. 4.

● 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 appliance requires placing the ESXI host into maintenance mode.

CAUTION: A green check mark does not indicate that the Health Check completed without any error or warning messages. A green Health Check mark only indicates that a health check step completed successfully. For more information, see KB article 000130130 PowerStore: Health Check shows all green when there are warnings . Install the PowerStore X model preupgrade package Use PowerStore Manager to install the preupgrade package on a PowerStore X model appliance.

Steps 1. Select the Settings icon, and then select Upgrades in the Cluster section. 2. Select the node firmware upgrade package in the Software packages table, and select Upgrade. The installation of the node firmware upgrade package takes approximately 10 to 15 minutes to complete. Results The node firmware upgrade package is not applied to the PowerStore X model appliance until the nodes of the appliance are rebooted.
PAGE 8
NOTE: Some user VMs may not migrate due to local dependencies or lack of resources. User intervention may be required to manually power off these user VMs to allow the ESXi host to enter maintenance mode. See ESXi and VM considerations on page 4 for more information. CAUTION: Do not manually power off the controller VMs, which are named PSTX-. 8.
PAGE 9
Rebooting the nodes to apply the preupgrade package and firmware upgrade package takes approximately 35 to 60 minutes per node. To reboot the nodes of appliance: a. Identify the peer and primary nodes on the appliance. See Minimizing internal ESXi host failover occurrences on page 5 for more information. b. In the vSphere Client, reboot the ESXi host on the peer node. For instructions, see the PowerStore Power Down and Reboot Procedures Guide. c.
