Downgrading the array support

The array support is available in a single package, VRTSaslapm, that includes Array Support Libraries (ASLs) and Array Policy Modules (APMs). Each major release of Dynamic Multi-Pathing includes the supported VRTSaslapm package, which is installed as part of the product installation. Between major releases, Symantec may provide additional array support through updates to the VRTSaslapm package.

If you have issues with an updated VRTSaslapm package, Symantec may recommend that you downgrade to a previous version of the ASL/APM package. You can only revert to a package that is supported for the installed release of Dynamic Multi-Pathing. To perform the downgrade while the system is online, do not remove the installed package. Instead, you can install the previous version of the package over the new package. This method prevents multiple instances of the VRTSaslapm package from being installed.

Use the following method to downgrade the VRTSaslapm package.

  2. To downgrade the package, use the following command:
    # pkgadd -a <response_file> -d ./VRTSaslapm.pkg
