HP 3PAR StoreServ 7400 2-node Administrator's Manual

NOTE:
In this example, test.rw1 can have VLUNs associated with it. The command will remember the
VLUN, remove the old snapshot, create a new snapshot, and recreate the VLUN with the new
snapshot.
After the snapshot is replaced, testuser1 must remount the filesystem on the host.
In the above example, the replaced copy (test.rw1) is a new copy of the database made from
the reference copy (test.ro1), and not from the database itself (test).
To get an up-to-date read-write copy of the original database, testuser1 must have updatevv
rights for volumes test.rw1 and test.ro1. Unmount the filesystem on the host before issuing
the following HP 3PAR CLI command:
cli% updatevv -ro test.rw1
This command removes test.rw1 and test.ro1, and replaces them with a new read-only
snapshot of test called test.ro1 and a new read/write snapshot of test.ro1 called
test.rw1. This gives the user an up-to-date read-write copy of the original database by creating
a new read-only snapshot of the original in addition to the new read-write copy.
NOTE:
In this example, only the read-write snapshot (test.rw1) can have a VLUN associated with it.
The command will remember the VLUN, remove the old snapshot, create a new snapshot, and
recreate the VLUN with the new snapshot. However, the read-only parent cannot have any VLUNs.
If the read-only parent (test.ro1) has any associated VLUNs, this command will fail.
After the snapshot is replaced, testuser1 must remount the filesystem on the host.
