NOTE: For P4000 G2 storage systems, the state is reported as OK, but the SnapUsed field
always reports 0%.

Accessing snapshot file systems
By default, snapshot file systems are mounted in two locations on the file serving nodes:
• /<snapshot_name>
• /<original_file_system>/.<snapshot_name>
For example, if you take a snapshot of the fs1 file system and name the snapshot fs1_snap1,
it will be mounted at /fs1_snap1 and at /fs1/.fs1_snap1.
X9000 clients must mount the snapshot file system (/<snapshot_name>) to access the contents
of the snapshot.
NFS and CIFS clients can access the contents of the snapshot through the original file system (such
as /fs1/.fs1_snap1) or they can mount the snapshot file system (in this example, /fs1_snap1).
The following window shows an NFS client browsing the snapshot file system .fs1_snap2 in the
fs1_nfs file system.
