After a successful PowerStore OE upgrade, which two actions are required?

Following a successful PowerStore Operating Environment (OE) upgrade, it is a mandatory best practice to perform post-upgrade verification. The primary tool for this is PowerStore Manager. Administrators must first verify the overall cluster health to ensure all components are online and functioning correctly. Secondly, it is crucial to review the system for any new alerts or warnings that may have been generated during or after the upgrade process. These two actions confirm that the upgrade was completed successfully and the system is in a stable, healthy state without any latent issues.

B. Reconnect hosts manually: PowerStore OE upgrades are designed to be non-disruptive to host I/O; hosts remain connected and do not require manual intervention.

D. Disable multipathing: Disabling multipathing is contrary to high-availability best practices as it would eliminate redundant paths to storage, increasing the risk of data unavailability.

1. Dell PowerStore: Software Upgrade Guide (Version 3.6)

Page 29

Section "Post-upgrade tasks". The guide explicitly states: "After the upgrade is complete

perform the following tasks: 1. Verify the health of the cluster. For more information

see the Dell PowerStore Manager Online Help. 2. Check for any alerts." This directly supports answers A and C.

2. Dell PowerStore: High Availability (White Paper)

Page 6

Section "PowerStoreOS non-disruptive upgrades". This document details that "PowerStoreOS upgrades are non-disruptive to host I/O... Host connectivity is maintained throughout the entire upgrade process." This confirms that manually reconnecting hosts (Option B) is not a required action.

Section "Multipathing software". This guide emphasizes the requirement for properly configured multipathing software (such as Dell PowerPath) on hosts for path failover and high availability

making the suggestion to disable it (Option D) incorrect.
