and/or model name.
Base-VXVM 4.1 allows an ASL to be added to a running VxVM system (see“Adding an ASL
package” on page 18 “). This means that you can add support for a particular disk array type
(including multipathing support by Dynamic Multipathing, DMP) without having to: stop
VxVM, reboot the system, or modify the VxVM package.
NOTE For the installed ASL to be discovered correctly, the array LUNs must be visible
to the operating system through multiple paths, and they must be
appropriately configured to support DMP. For instructions on how to configure
the array correctly, please contact the array vendor.
You can also remove ASL packages from a running VxVM system (see “Removing an ASL
Package” on page 20“). If the associated disk array type contains active volumes, these will
remain available during and after the addition or removal of the ASL package.
Only one version of an ASL for a specific type/model of disk array can be active in the system.
To install a different version of an ASL, you need to first remove the previous version of the
ASL package, then install the new package (see “Upgrading an ASL Package” on page 20“).
Commands Used to Maintain ASL Packages
The following packaging commands are available for installing, removing, and listing ASL
packages.
See the appropriate manual page for more information on these commands.
Adding an ASL package
Only one version of an ASL can be active in the system. If you find a version of the ASL is
already installed, you need to refer to “Upgrading an ASL Package” on page 20“.
