The Storage Foundation 5.1 SP1 release includes all array support in a single fileset, VRTSaslapm. The array support fileset includes the array support previously included in the VRTSvxvm fileset. The array support fileset also includes support previously packaged as external array support libraries (ASLs) and array policy modules (APMs).

See the 5.1 SP1 Hardware Compatibility List for information about supported arrays.

When you upgrade Storage Foundation products with the product installer, the installer automatically upgrades the array support. If you upgrade Storage Foundation products with manual steps, you should remove any external ASLs or APMs that were installed previously on your system. The installation of the VRTSvxvm fileset exits with an error if external ASLs or APMs are detected.

After you have installed Storage Foundation 5.1 SP1, Symantec provides support for new disk arrays though updates to the VRTSaslapm package.

For more information about array support, see the Veritas Volume Manager Administrator's Guide.
