Retaining older Veritas Volume Manager releases

To retain an older version of Veritas Volume Manager and not upgrade to the current release shipped with Veritas Storage Foundation, you must set a special environment variable before starting the upgrade procedure.

• If you are using Bourne or Korn shell (sh or ksh), use the commands:

        $ NO_VXVM_UPGRADE=yes

     $ export NO_VXVM_UPGRADE
 

• If you are using a C shell (csh or tcsh), use the command:

% setenv NO_VXVM_UPGRADE yes

The installation program checks for the NO_VXVM_UPGRADE environment variable during the upgrade and displays messages similar to the following if this variable is set:

Checking existing package installation...

NOTICE: Package VRTSvxvm is being skipped (NO_VXVM_UPGRADE set).

NOTICE: Package VRTSvmsa is being skipped (NO_VXVM_UPGRADE set).

  Note   We recommend that you upgrade to the current version of Veritas Volume Manager if you want to use the Database FlashSnap or Storage Mapping options.
