Recovering from the failure of vxsnap reattach or refresh

If a vxsnap reattach or vxsnap refresh operation fails, VxVM attempts to restart the resynchronization when the volume is recovered. The volume will be started with the synchronization in the background.

This procedure requires that the disk group version is 170.

The volume being refreshed may go into the DISABLED state, be marked invalid and be rendered unstartable.

To recover from the failure of the vxsnap reattach or refresh commands

  1. Use the following command to check that the inst_invalid flag is set to on:
    # vxprint [-g diskgroup] -F%inst_invalid volume
  2. Use the vxmend command to clear the volume's tutil0 field:
    # vxmend [-g diskgroup] clear tutil0 volume
  3. Use the following command to start the volume:
    # vxvol [-g diskgroup] start volume
  4. Re-run the failed reattach or refresh command.

    This results in a full resynchronization of the volume. Alternatively, remove the snapshot volume and recreate it if required.
