For example, to take a snapshot of the snap path /fs1/dir1 with the snap name snap1,
issue the following command:
# ibrix_snap -c -f fs1 -P /fs1/dir1 -n snap1
4. List the snapshot that is created using the following command:
# ibrix_snap -l -s
For more information about these commands, see the HP StoreAll Storage CLI Reference Guide,
which is available on the following HP website:

Reclaiming File System Space Previously Used for Snapshots
Snapshot reclamation tasks are used to reclaim file system space previously used by snapshots
that have been deleted. The reclamation task runs on an entire file system, not on a specific snapshot
directory tree within that file system. If a file system includes two snapshot directory trees, space
is reclaimed in both snapshot directory trees.
This section explains how to run a snapshot reclamation task through the StoreAll OS CLI.
1. Create a mounted file system using the LUNs that are exported from the HP 3PAR StoreServ
Storage. See “Mounting a File System” (page 28).
2. To take an on-demand snapshot from the StoreAll OS CLI, use the following command:
# ibrix_snap -c -f FSNAME -P SNAPTREEPATH -n NAMEPATTERN
For example, to take a snapshot of the snap path /fs1/dir1 with the snap name snap1,
issue the following command:
# ibrix_snap -c -f fs1 -P /fs1/dir1 -n snap1
3. To delete the snapshot from the StoreAll OS CLI, use the following command:
# ibrix_snap -d -f FSNAME -P SNAPTREEPATH -n SNAPSHOT NAME
For example, to delete a snapshot with the name 2012-04-24T163309_snap1 from file
system fs1, use the following command:
# ibrix_snap -d -f fs1 -P /fs1/dir2 -n 2012-04-24T163309_snap1
4. To start a reclamation task from the StoreAll OS CLI, use the following command:
# ibrix_snapreclamation -r -f FSNAME [-s {max speed | maxspace}] [-v]
For example, to start a reclamation task on file system fs1, issue the following command:
# ibrix_snapreclamation -r -f fs1
