VSS compliant
mode
(HP StorageWorks Disk Array XP VSS provider specific term)
One of two XP VSS hardware provider operation modes. When
the XP provider is in the VSS compliant mode, the source volume
(P-VOL) and its replica (S-VOL) are in simplex, unpaired state
after a backup. Therefore the number of replicas (S-VOLs per a
P-VOL) rotated is not limited. Restore from a backup in such a
configuration is possible only by switching of the disks.
