Arcserve Backup Not Installed on Mirrored Disks

If any disk in a mirrored set becomes damaged, but the cluster nodes are undamaged, and Arcserve Backup is not installed on the mirrored disk, you must replace the disk without halting the current application.

Note: See the NEC document NEC ExpressCluster System Construction Guide [Operation/Maintenance] 4.2.9 Replacement of Damaged Disk for information.
