Repairing A Storage System - HP StoreVirtual 4000 User Manual

1. Select the affected storage system in the navigation window.
The storage system icon blinks in the tree.
2. Check the Status line on the Details tab.
If status is Storage System Overloaded, wait up to 10 minutes and check the status again.
The status may return to Normal and the storage system will be resyncing.
If status is Storage System Inoperable, reboot the storage system and see if it returns to
Normal, when it comes back up.
If either status reoccurs, it may be an indication that the underlying hardware problem
still exists.

Repairing a storage system

Repairing a storage system allows you to replace a failed disk in a storage system that contains
volumes configured for data protection levels other than Network RAID-0, and trigger only one
resynchronization of the data, rather than a complete restripe. Resynchronizing the data is a shorter
operation than a restripe.
Because of the data protection level, removing and returning the storage system to the cluster would
normally cause the remaining storage systems in the cluster to restripe the data twice—once when
the storage system is removed from the cluster and once when it is returned.
However, the Repair Storage System feature creates a placeholder in the cluster, in the form of a
"ghost" storage system. This ghost storage system keeps the cluster intact while you remove the
storage system, replace the disk, configure RAID, and return the storage system to the cluster. The
returned storage system only has to resynchronize with the other two storage systems in the cluster.
