Downgrading the array support


Downgrading the array support
Prev	Restoring a previous array support library	Next

The array support is available in a single package, VRTSaslapm, that includes Array Support Libraries (ASLs) and Array Policy Modules (APMs). After Veritas Volume Manager 5.1 is installed, Symantec will provide additional array support through updates to the VRTSaslapm package.

In some circumstances, you may need to revert to a previous version of the ASL/APM package to the version previously installed. 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.

To downgrade the ASL/APM package:

Create a response file to the pkgadd command that specifies instance=overwrite. The following example shows a response file:

# Use is subject to license terms.
#
#ident  "@(#)default    1.7     04/12/21 SMI"

space=ask
setuid=ask
conflict=ask
action=ask
networktimeout=60
networkretries=3
authentication=quit
keystore=/var/sadm/security

basedir=default

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