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. Schedule time for upgrade.
