Limitations on EMC CLARiiON IP4700 Devices

The following are the limitations when you use the EMC CLARiiON IP4700 Celerra NAS servers with the NDMP NAS option:

Note: Some of these limitations are based on the NDMP version used on the NAS server.

• You can perform only full volume backups. However, you can perform restore operations on selected files or folders.
• Backup and restore operations do not support any kind of filtering.
• Snapshot functionality is not supported.
• Direct Access Restore (DAR) is not supported.
• The option does not display a progress bar or percentage complete statistics in the Job Monitor dialog.
• EMC CLARiiON IP4700 restore operations only support the option Create Entire Path from the Root on the Destination tab of the Restore Manager Global Options dialog.

In addition, the NDMP NAS Option cannot determine the volumes created on the IP4700 server. You must determine these volumes manually and configure the file nas.cfg. View the web-based Administrative Interface to determine the volume names that you must include in the nas.cfg file.

The following is an example of volume information:

Name		Label	Size	Space Used	Status
A0			264910	15723		RDY
B0			264910	15569		RDY

In this case, you must add the volume names A0 and B0 in the nas.cfg file.
