Downgrading the array support

The array support is available in a single rpm, VRTSaslapm, that includes Array Support Libraries (ASLs) and Array Policy Modules (APMs). Each major release of Veritas Storage Foundation and High Availability Solutions includes the supported VRTSaslapm rpm, which is installed as part of the product installation. Between major releases, Symantec may provide additional array support through updates to the VRTSaslapm rpm.

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

Use the following method to downgrade the VRTSaslapm rpm.
