15.4
Replacing Virtual Volume Snapshots
3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
This command removes test.ro and replaces it with a new read-only snapshot of test.
This new volume is also called
test.ro.
After the snapshot is replaced,
testuser1 must remount the filesystem on the host.
15.4.2 Replacing a Read-Write Snapshot
The following example shows how to replace a read-write snapshot volume with a new
read-write snapshot volume.
In this example:
■ test is a base volume (or a read-write snapshot).
This volume holds the database.
■ test.ro1 is a read-only snapshot of test.
This snapshot is the reference copy of the database.
■ test.rw1 is a read-write snapshot of test.ro1.
This is a snapshot of the reference copy of the database, created for development purposes.
■ testuser1 is a user with updatevv privileges for volume test.rw1
See 15.3 Setting Administrative Permissions on page 15.2 for instructions on setting
privileges for this command.
■ When test.rw1 needs to be restored, testuser1 unmounts the filesystem on the host
and then issues the following InForm CLI command to replace test copy
test.rw1 with a
new copy:
This command removes
test.rw1 and replaces it with a new snapshot of test.ro1. This
new volume is also called
test.rw1.
NOTE: In this example, test.ro can have a VLUN associated with it. The
command will remember the VLUN, remove the snapshot, create the new
snapshot, and re-create the VLUN with the new snapshot.
cli% updatevv test.rw1
