To solve the issue, do the following:

  1. Run /etc/vx/bin/vxconfigbackup dgname to identify the disk group which is failing.

    # /etc/vx/cbr/bk/vxconfigbackup dg1

    VxVM vxconfigbackup ERROR V-5-2-3720 Unexpected error, dgid mismatch.

    The command result shows that the disk group named dg1 is failing.
     
  2. Rename the backup repository for the failing disk group:

    # mv/etc/vx/cbr/bk/dg1.1188102555.37.hostid /etc/vx/cbr/bk/previous_dg1.1188102555.37.hostid
     
  3. Run the vxconfigbackup again to verify if the issue is solved.

    #  vxconfigbackup dg1

    Start backing up disk group dg1 to

    /etc/vx/cbr/bk/dg1.1188102555.37.hostid ...

    VxVM  NOTICE V-5-2-3100 Backup complete for diskgroup: dg1
