Managing OUIDs for snapshots and VDG snapshots
For information about OUIDs, see “Working with OpenVMS” on page 144.
By default, all snapshots 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 snapshot’s OUID value to 0.
You can only change the OUID for one snapshot at a time.
NOTE:
Keep track of OUID assignments. SVSP does not perform verification for redundancy when OUIDs
are changed.
Managing OUIDs for snapshots
To change an OUID for a snapshot:
1. In the navigation tree, expand the Entities node.
2. Click the Snapshot node. The snapshots list appears in the list area.
