You cannot make pairs of the volumes.
Specify the logical volumes satisfying the conditions described in
Table 2 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
