Secondary Volume (S-VOL) (HP

term)
Secondary Volumes, or S-VOLs, are XP
LDEVs that act as a secondary CA or
BC mirror of another LDEV (a P-VOL).
In the case of CA, S-VOLs can be used
as failover devices in a MetroCluster
configuration. The S-VOLs are assigned
separate SCSI addresses, different from
the addresses used by the P-VOLs.
See also Primary Volume (P-VOL).

shadow copy (MS VSS specific term)
A volume that represents a duplicate of
the original volume at a certain point in

process continues, but the shadow copy
of the volume remains constant.
