HP StorageWorks SAN Virtualization Services Platform Manager user guide (5697-0295, January 2010)

By default, all virtual disks are assigned an OUID of 0, which is regarded as having no OUID
assignment.
• To effectively assign an OUID, you must change the OUID value from 0 to any other value between
1 and 32767.
• After assigning an OUID value, you can change the OUID value at any time.
• To effectively remove an OUID assignment, change the virtual disk’s OUID value to 0.
You can only change the OUID for one virtual disk at a time.
NOTE:
Keep track of OUID assignments. SVSP does not perform verification for redundancy when OUIDs
are changed.
To change an OUID for a virtual disk:
1. In the navigation tree, expand the Entities node.
2. Click the Virtual Disk node. The virtual disks list appears in the list area.
3. Right-click the virtual disk for which you want to change the OUID.
4. Select Manage > Set OpenVMS UID. The Set OpenVMS UID screen appears.
5. Change the assigned OUID value.
6. Click Next. A confirmation screen appears.
7. Click Finish. The virtual disk’s OUID is changed.
Deleting virtual disks
VSM enables you to delete a virtual disk if:
• No snapshot PiTs have been created for the virtual disk.
• The virtual disk either has no host permissions defined, or all hosts that have permission to access
the virtual disk have Normal or Degraded status.
To delete a virtual disk:
1. In the navigation tree, expand the Entities node.
2. Click the Virtual Disk node. The virtual disks list appears in the list area.
3. Right-click the virtual disk you want to delete.
4. Select Delete. A confirmation screen appears.
5. Click Finish. The virtual disk is deleted.
