Veritas Storage Foundation for DB2 provides "deep" mapping information and performance statistics for supported storage arrays. Deep mapping information consists of identifying the physical disks that comprise each LUN and the hardware RAID information for the LUNs.

Veritas Array Integration Layer (VAIL) software interfaces third-party hardware storage arrays with Veritas storage software. VAIL providers are software modules that enable Veritas applications to discover, query, and manage third-party storage arrays.

For the most up-to-date array support information, see the appropriate hardware compatibility list (HCL) on the Veritas Technical Support Web page at:

http://support.veritas.com

If you want to use storage array information accessible through the VAIL providers, install VAIL and perform any required configuration for the storage arrays and VAIL providers. To use deep mapping services and performance statistics for supported storage arrays, you must install both VAIL and Veritas Mapping Services (VxMS).

You will need to install required third-party array CLIs and APIs on the host where you are going to install VAIL before you install VAIL. If you install any required CLI or API after you install VAIL, rescan the arrays so that Veritas Storage Foundation for DB2 can discover them.

For detailed information about supported array models, see the Veritas Array Integration Layer Array Configuration Guide.
