For each DSU that needs protection, the DSU's volume on the
NearStore system needs to be configured as the source of a volume
SnapMirror relationship. For details on how to configure volume
SnapMirror relationships, refer to the volume
SnapMirror section of this document. The destination of each volume
SnapMirror relationship needs to reside on a different
NearStore system than the source and have a name identical to that of the source volume.
Note: Identical names for the source and the destination volumes is not a generic requirement for volume
SnapMirror when used outside the context of
SnapVault for NetBackup. It is not in any way enforced when configuring volume
SnapMirror relationships. However, for failovers to work in the context of
SnapVault for NetBackup, the volume names must be identical on the
SnapMirror source and destination.
