Adding DMP support for a new disk array

You can dynamically add support for a new type of disk array. The support comes in the form of Array Support Libraries (ASLs) that are developed by Veritas. Veritas provides support for new disk arrays through updates to the VRTSaslapm fileset. To determine if an updated VRTSaslapm fileset is available for download, refer to the hardware compatibility list tech note. The hardware compatibility list provides a link to the latest fileset for download and instructions for installing the VRTSaslapm fileset. You can upgrade the VRTSaslapm fileset while the system is online; you do not need to stop the applications.

To access the hardware compatibility list, go to the following URL:

Each VRTSaslapm fileset is specific for the Dynamic Multi-Pathing version. Be sure to install the VRTSaslapm fileset that supports the installed version of Dynamic Multi-Pathing.

The new disk array does not need to be already connected to the system when the VRTSaslapm fileset is installed. If any of the disks in the new disk array are subsequently connected, you need to trigger OS device discovery using the cfgmgr command and then trigger DDL device discovery using the vxdctl enable command.

If you need to remove the latest VRTSaslapm fileset, you can revert to the previously installed version. For the detailed procedure, refer to the Veritas InfoScale Troubleshooting Guide.
