IT09689: UNABLE TO IMPORT VOLUME GROUP AND ERRONEOUS MESSAGE THAT THE VOLUME GROUP IS ALREADY VARIED ON IN OTHER NODE

Download Information: Version 4.1.3 IBM Spectrum Protect Snapshot

APAR status

• Closed as program error.

Error description

• Even when the fixes for APARs IC94831 and IC99980 have been
  applied, and the AIX APAR family "RECREATEVG SUPPORT FOR
  MULTI-NODE VARYON PROTECTION" are applied, Tivoli Storage
  FlashCopy Manager for UNIX and Linux tape_backup operations
  may fail with messages like the following in the summary log:
  
  GEN 16:36:46 (952) FMM1232I Executing operation 'mount' on
   host 'hostname'.
  MNT 16:37:05 (a54) FMM0644E Error on running command:
   importvg -y VGNAME -n hdisk pvname
   0516-1971 varyonvg: The volume group is already varied on in
   other node. varyoff
   the volume group in other node and retry the varyonvg, or use
   -O flag to
   force varyon the volume group.

Local fix

• 1. Create a file (used as shell script) called "importvg" in
  the Tivoli FlashCopy Manager instance directory on the backup
  system.  This importvg script will have one line:
  
   /usr/sbin/importvg -O $*
  
  This file "importvg" must have the same owner and permissions
  as /usr/sbin/importvg.
  
  2. Modify the PATH environment variable for the acsgen process
  running on the backup system. To achieve this, do the
  following:
  - rename /<fcm_instance_path>/acsgen to
    /<fcm_instance_path>/acsgen_orig
   (keep the original permissions and owner).
  - create a new file with the name 'acsgen' and exactly the
    same permissions as original acsgen (incl. s-bit and
    root:dba owner).
  - in the new file 'acsgen' :
    a. modify PATH
       (e.g. export PATH=/<fcm_instance_path>/:$PATH),
       so that the replaced importvg script will be called instead
       of the original one.
    b. call the original acsgen_orig
       (/<fcm_installation_path>/acsgen_orig $*).
       This would result in a script like:
       "
       export PATH=/<fcm_instance_path>/:$PATH
        /<fcm_instance_path>/acsgen_orig $*
       "
