8.2.2 Rollback with Read-Write Virtual Copies
The difference between a read-only and a read-write virtual copy depends on whether the
read-write virtual copy has been exported and if any I/O operations have been applied on the
copy or not.
■
For a cloned database on the backup host, you need to perform log switches until all online
redo logs are switched to archive log files. The cloned database must then be shut down.
All file systems used by the cloned database have to be manually unmounted, and remain
offline with the
umount
and
removevlun
commands.

NOTE: Be sure to manually unmount the file systems used by the cloned database
on the backup host. Do not use the
vcdba_umount
utility, which not only
unmounts the file systems, but also removes the read-write virtual copy from the
InServ system.
