a higher version of SAN/iQ

•Added a check to 9.0 CMC online upgrades for any existing hardware problems in a pre-9.0

storage system during the upgrade pre-qualification tests, and ensures that the hardware passes

the required tests before proceeding with the upgrade. If a hardware problem is detected, the

upgrade fails with an appropriate error message and can be retried after resolving the problem.

•9.0 CMC online upgrades now provide the ability to apply prerequisite patches to storage systems

before upgrading to the appropriate SAN/iQ version

•Corrected the 9.0 CLI makePrimary command to retain the thin provisioning attribute of the

volume/snapshot being converted to primary

you have to upgrade to an 8.x version before upgrading to

Version 9.5.

If you are running iSCSI load balancing, you must have a

Virtual IP Address configured on each cluster.

Are you running iSCSI load balancing? Verify that each

cluster has a VIP configured.

The SAN/iQ software upgrade will reboot the storage system.

Therefore, for volumes to remain online during the upgrade

process, they must be Network RAID-5 or higher. Volumes

that are Network RAID-0 should be disconnected (logged off)

from the application server(s). Rebooting the storage system

will cause all iSCSI sessions on that storage system to be

terminated and recovered to one of the remaining storage

systems in the cluster. Consequently, application IO to the

volume may stop until the iSCSI session is recovered. Consider

upgrading during off-peak time (if possible) to avoid

application impact.

The actual time to upgrade a storage system or a

management group depends on the specific platform(s) and

configuration.

Schedule time for upgrade.

Upgrade the components in the following order:Upgrading the CMC, the SAN/iQ software, and the Solution

Pack components. 1. The CMC, including CLI, MIBs and FOM.
