This appendix describes specific functionality available for virtualized volume resources for which
virtual IDs are assigned.
About managing storage resources that have virtual IDs
When virtualized volume resources are migrated from an existing storage system to a new storage
system, virtual ID information (such as existing storage system model, serial number, ports, LDEV IDs,
and so on) is assigned to the volumes of the new storage system after migration in order to provide
host access to migrated volumes. The virtual ID information of the migrated volume resource can be
viewed in Command View AE Suite. By using virtual ID information, you can identify migrated volume
resources and perform tasks that change their configuration.
You can perform any of the following tasks on resources that have virtual IDs:
• Expand THP/Smart volumes
• Reclaim zero pages of THP/Smart volumes
• Edit tier relocation of Smart volumes
• Edit tiering policy of Smart volumes
• Manage data placement profiles of Smart volumes
•

Notes:
1. For volumes for which no virtual ID is specified, you can specify new virtual IDs, and then allocate
the volumes to host groups for which virtual IDs have already been specified.
2. You can also delete virtual IDs at the same time that volumes are unallocated.
3. To perform operations on a copy pair that contains volumes for which virtual IDs have been
specified, you must update in advance the information (physical ID information) of the post-migra-
tion storage system with the configuration definition file of the copy pair. For details about the
