COMMAND
vcdba_umount
SYNOPSIS
vcdba_umount -s <oracle_sid> -p <primary_host> -t <timestamp>
[-f ] [-v]
DESCRIPTION
Unmounts a virtual copy.
The
vcdba_umount command unmounts a mounted database virtual copy. The virtual copy
must have
Mounted or Mounted(P) status in order to be unmounted. The virtual copy
unmounting process only removes the read-write virtual copy; the read-only virtual copy
remains intact.
Unmounting a database virtual copy involves the following actions:
■ For an ASM-managed database, if the ASM version on the backup host is 10.2.0.5 or
11.1.0.7, unmounting the virtual copy drops the ASM diskgroups that are contained in the
virtual copy and cleans up the ASM disks.
■ If the ASM version on the backup is lower than those listed in the previous bullet,
unmounting shuts down the ASM instance and cleans up ASM disks.
■ Unmounts all snapshot file systems if the database files reside on file systems.
■ Destroys all snapshot VxVM disk groups and their VxVM volumes if the database files reside
on VxVM volumes.
■ Deports the read-write virtual copy from the backup host.
■ Removes the read-write virtual copy.
You must run this command as a super user from the backup host. To allow the Oracle
Database Administrator (Oracle Owner) to run this command, an identical Oracle Database
Administrator user must exist on backup host. In addition, permission on the 3PAR Recovery
Manager Installation and Repository directories must be changed appropriately.
