Sun Microsystems 7000 manual Advanced Data Services, Snapshots, Cloning a Snapshot

4.0 Advanced Data Services

The following section gives a high-level overview on how to enable snapshots and replication on the Sun Storage 7000 Unified Storage System to use with VMware ESX. It is outside the scope of this document to delve into the lower-level implementation details for snapshot and replication. You can refer to the online Sun Storage 7000 Help Wiki for details on using both features (or Sun Storage Unified Storage System Administration Guide at http://docs.sun.com/source/820-4167-10/).

4.1 Snapshots

Snapshots can be taken at the project or the share (file system or iSCSI LUN) level. To take a snapshot use the following procedure:

1.Select Shares.

2.Select the Share or Project that you want to create a snapshot on.

3.Select the Snapshots tab.

4.Click (+) to add a new manual snapshot or select the Schedule tab and click (+) to add a new scheduled snapshot.

5.Click Apply.

4.2Cloning a Snapshot

To access the snapshot as a readable/writable file system or LUN, the snapshot must be cloned and then mounted on the VMware ESX Server.

To clone a snaphost use the following procedure:

1.Select Shares.

2.Select the Share or Project that contains the snapshot you wish to clone.

3.Select the Snapshots tab.

4.Select the snapshot you wish to clone.

5.Click (+) to Clone snapshot as a new share.

6.Give the clone a unique name to identify it as separate from the snapshot. For example: fs1-clone.

7.Click Apply.

You can now use the procedures for adding a new NFS file system or a new iSCSI LUN to VMware ESX to access the clone.
