You cannot make pairs of the volumes.
Specify the logical volumes satisfying the conditions described in
as the source and target
volumes. The source and target volumes must be specified by LDEV ID.
Source volumes
The following describes whether volumes can be used as source volumes:
•
Volumes set as command devices (reserved for use by hosts) cannot be used as source volumes.
•
Volumes in an abnormal or inaccessible condition (for example, fenced) cannot be used as source
volumes.
•
Volumes with Cache LUN data stored in cache cannot be used as source volumes.
•
iSCSI volumes (volumes to which paths are defined from iSCSI ports) cannot be used as source
volumes.
•
Volumes that HP StorageWorks Continuous Access XP Journal or Universal Replicator for z/OS® uses
as a data or journal volume cannot be used as source volumes.
•
Volumes reserved by a migration program other than Auto LUN XP cannot be used as source volumes.
•
Volumes on which the RAID Manager is performing volume migration operations.
•
Volumes that form a Snapshot XP pair cannot be used as source volumes.
•
Volumes used by Continous Access XP Journal or Universal Replicator for z/OS® as a journal volume.
•
Volumes used by the IBM 3990 Concurrent Copy (CC) host software function.
•
Virtual and pool volumes cannot be used as source volumes.
•
Inaccessible volumes, or volumes in an abnormal state cannot be used as source volumes (for example,
pinned track or fenced volumes).
•
Volumes being shredded.
•
Universal Replicator for z/OS®: If the status of a Universal Replicator for z/OS® volume is Pending
duplex or Duplex, the volume cannot be used as a source volume. Note that if you specify a Universal
Replicator for z/OS® volume as a source volume, you cannot specify an external volume as the target
volume.
•
Continuous Access XP Journal. If the status of a HP StorageWorks Continuous Access XP Journal volume
is PSUS, PSUE, or SMPL, the volume can be used as a source volume. If not, the volume cannot be used
as a source volume. When a Continuous Access XP Journal pair is deleted from the MCU, the status of
both volumes changes to SMPL, and both volumes can be used as source volumes. When a Continuous
Access XP pair is deleted from the RCU, the status of the P-VOL changes to PSUS, the status of the S-VOL
changes to SMPL, and both volumes can be used as source volumes.If the status of a Continuous
Access XP Journal volume is COPY or PAIR, the volume cannot be used as a source volume. Note that
if you specify a Continuous Access XP Journal volume as a source volume, you cannot specify an
external volume as the target volume.
•
Business Copy. Using a BC volume as a source volume depends on the status and cascade
configuration of the volume. If the status of a BC volume is not split-pending COPY(SP) or PSUS(SP), the
