Whenever I try to backup the configuration, warning is shown as below. Also when i try to restore it, the operation fails.

/etc/vx/bin/vxconfigbackup -l /opt/configbackup

    Please post output of  'vxdg list abcdg'

    Explanation of 'flush' option from man page:

          flush    Rewrites all  on-disk  structures  (disk  headers,
                   configuration   copies,  and  kernel  log  copies)
                   managed by VxVM for  the  specified  disk  groups.
                   Also,  if  any  configuration  copies are disabled
                   (for example, due to I/O failures),  this  command
                   rewrites  those configuration copies, and attempts
                   to enable them.

    Hi Srini,

    I tried the vxdg flush command still the problem persists. The answer to your questions is 'No changes/sharing'. Now what?

     

    Regards.

    Hi Jbert,

     

    Generally this means Diskgroup configuration copy saved on the disk is not matching

    with the config copy on kernel. Was there any changes made to SAN recently?

    Is Storage shared with other hosts?

     

    Try vxconfigbackup after running # vxdg flush command.

    This command will flush config copy from kernel to on-disk.

     

    Regards
