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.

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.
