16.4
Replacing Virtual Volume Snapshots
3PAR InForm OS CLI Administrator’s Manual InForm OS Version 2.2.4
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.
16.4.2 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 16.3 Setting Administrative Permissions on page 16.2 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
