Switches

The following switch supports the ADD SNAPSHOT_UNITS command:

USE_PARENT_WWID

Causes the snapshot unit to be created with a special World Wide ID (WWID)

derived from that of the parent or source unit. If the special WWID for the

specified source unit is in use, then a new WWID is automatically allocated,

and a warning message is displayed.

Note: The USE_PARENT_WWID switch limits the number of WWIDs that an

operating system needs to track. This can become an issue if snapshots are created

and subsequently deleted from the same source or parent unit on a regular basis.

Example

To create unit D4, which consists of storageset RAID4 and which becomes a

snapshot of unit D1, enter:

ADD SNAPSHOT_UNITS D4 RAID4 D1
