How to recover from failure with sconlinebackup in HP-UX 11.11
Hi,

Can someone help me to come out of this error?
We have a HP-UX 11.11 system. I started a scbackup (online) as mirroring was enabled and the backup went on successfully. But from the scbackup logs I see that after the splitting of the logical volumes for online backup usually a MERGE-DELETE process gets activated on splitted Logical Volumes which doesn't seem to have started. As a result the backup logical volumes still exists

There is a full day between these events. Did a second backup start and not finish?

First check every one of the mounted "backup" partitions with "fuser" on the mountpoint and make sure that no process whatsover has any of these partitions open. This is in case your previous backup is still running somehow and perhaps waiting for a tape?
Your vg00 is the largest I have ever seen (it would normally be just Operating System). Does it actually fit on a tape?


The outline plan is to work up your list of "backup" mountpoints from the bottom up ensuring that you "umount" in the reverse order of the original "mount".

Outline of what do do, but please DYOR and get a colleague to double check every command before typing.

Code:
Using the least volatile partition on your list as an example:

# Look at "Mirror copies" and check that it is definitely one less than is normal.
/usr/sbin/lvdisplay /dev/vg00/lvol9
#
# Unmount the filesystem
/usr/sbin/umount /sconlinebackup/var/adm/crash
#
# Merge the split mirror back:
/usr/sbin/lvmerge /dev/vg00/lvol9backup /dev/vg00/lvol9
#
# Look at "Mirror copies" and check that is it now normal
/usr/sbin/lvdisplay /dev/vg00/lvol9

Beware that "lvmerge" is very quick for a filesystem which has not changed but could
 take an hour or more for a Logical Volume which is now quite different.
In my experience you can only run one "lvmerge" at any one time.

Hi Methyl,

Thanks your proposal did work. Also I saw there is another option in scbackup i.e. scbackup -R that also does the MERGE-DELETE function.
