Auto LUN XP user guide for the XP12000/XP10000 17
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.
TrueCopy for z/OS®: If the status of a TrueCopy for z/OS® volume is suspended or simplex, the volume
can be used as a source volume. If not, the volume cannot be used as a source volume. When a TrueCopy
for z/OS® volume is deleted from the MCU, the status of both volumes changes to simplex, and both
volumes can be used as source volumes. When a TrueCopy for z/OS® volume is deleted from the RCU,
the status of the M-VOL changes to suspended and the status of the R-VOL changes to simplex, and both
volumes can be used as source volumes.
TrueCopy: If the status of a TrueCopy 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 TrueCopy 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 TrueCopy pair is deleted from the RCU, the status of the P-VOL changes to PSUS and the status of
the S-VOL changes to SMPL, and both volumes can be used as source volumes.
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.
