Restore the original environment
In the event of an upgrade failure, you have the option to revert to the original boot environment prior to the upgrade using the following procedure:
To restore the original environment
- Stop and unbind the guest:
# ldm stop guest # ldm unbind guest
- Restore the boot volume from the backup snapshot volume:
# vxsnap -g disk_group restore boot_volume source=backup_vol
This operation restores the boot image to the point-in-time that the snapshot was taken prior to the upgrade.
See Using VxVM snapshot as a backup copy of the boot image during the upgrade.
- Ensure that the boot volume is completely restored
# vxtask list
The output of the vxtask list command shows if any currently synchronize operation is in progress. If there is any such task in progress then you have to wait until it completes.
# vxsnap -g disk_group print
This should show that the dirty percentage is 0% and the valid percentage is 100% for both the original and the snapshot volume. If not, wait until the original and the snapshot volumes are synchronized.
- Bind and restart the guest:
# ldm bind guest # ldm start guest
- Verify that the boot environment is restored correctly.
- Reattach the snapshot volume to the source volume as a plex. This operation causes the backup plex to get re-attached back to the boot volume as a mirror, making the volume redundant again with two mirrored plexes:
# vxsnap -g disk_group reattach backup_vol source=boot_volume
