Renaming Disks in Disk Groups

You can rename a disk in a disk group with the ALTER DISKGROUP RENAME DISK SQL statement. In one SQL statement, you can rename one or multiple disks, or rename all disks in a disk group using the RENAME DISKS ALL clause.

For example, you can rename disks as follows:

SQL> ALTER DISKGROUP fra2 MOUNT RESTRICTED;

SQL> ALTER DISKGROUP fra2 RENAME DISK 'FRA1_0001' TO 'FRA2_0001', 
       'FRA1_0002' TO 'FRA2_0002';

The ALTER DISKGROUP diskgroupname RENAME DISKS ALL statement can be run after the renamedg utility to change the names of the disks in the renamed disk group. For information about renamedg, refer to "Renaming Disks Groups".

When you run the ALTER DISKGROUP diskgroupname RENAME DISKS ALL statement, any disk name that is not in the format diskgroupname_number is renamed to that format. Disk names that are already in the diskgroupname_number format are not changed.

You can only use the RENAME DISK operation when the disk group that contains the disk is in the MOUNT RESTRICTED state. If any disks in the disk group are offline, then the RENAME operation fails. If the new disk name exists, then the RENAME operation fails. You must have SYSASM privileges to rename a disk.
