■ Downgrading the array support

Downgrading the array support

The array support is available in a single depot, VRTSaslapm, that includes Array

Support Libraries (ASLs) and Array Policy Modules (APMs). Each major release

of Veritas Volume Manager includes the supported VRTSaslapm depot, which is

installed as part of the product installation. Between major releases, Symantec

may provide additional array support through updates to the VRTSaslapm depot.

In some circumstances, you may need to revert to a previous version of the

ASL/APM depot. You can only revert to a depot that is supported for the installed

release of Veritas Volume Manager. To perform the downgrade while the system

is online, do not remove the installed depot. Instead, you can install the previous

version of the depot over the new depot. This method prevents multiple instances

of the VRTSaslapm depot from being installed.

Use the following method to downgrade the VRTSaslapm depot.

◆

Specify the previous version of the VRTSaslapm depot to the following

command:

# swinstall -x allow_downdate=true -s source_path VRTSaslapm

Where source_path is the location of the depot.
