Michael,
it is browseable from the status. That's what mminfo tells you.
However the index is empty. You can verify this with "nsrls client".
Yes, but why? The index should have been rebuilt with "scanner -i".
I agree. But what would happen if you instead scanned the tape to get
the ssid (assuming you don't already know it), and then you used scanner
to perform a raw recover using uasm and relocated it to another target
directory, just to check, and then maybe moved it into place. Would that
work?
Well, I can (and did) do a saveset recover. The whole saveset was only
like 14G, so it wasn't too bad to do that, and then find what I wanted.
As it turns out, apparently the problem was ... that I'm an idiot. :-) I
*thought* I had done "scanner -i", and instead I had only done "scanner
-m". So of course there was no index.
I am now doing "scanner -i", and it does look like it's rebuilding the
index, as "nsrls client" now shows 2500 records ...
Mind you, I still have my problem from last week, where I did a "scanner
-m", and then a "scanner -i -S<ssid>", to 3 tapes created on yet another
NW server. And those savesets are still not browsable, even after doing
"-i" (verified - the command is still on the screen, at the shell prompt".
Is it possible that your operation from last week hasn't actually
finished yet so it hasn't written anything to disk? In other words,
kinda like when you delete a file, but a process still has it open. The
disk space isn't freed up yet. Or maybe the tapes weren't run in the
correct order. You should be able to tell by looking at the
synchronization chunk (B, C, S or E). I've found that any save sets that
start on Tape 1 and finish on tape 2 will be identified as 'B' on tape 1
and 'E' on tape 2. Any save set that's completely contained on the tape
is marked as 'E'. I suppose if a save set it contained on three on more
tapes then maybe the middle portions will be marked as 'C'. Not sure.
But this other tape, from the other NW server, does seem to be doing the
"-m" and then "-i" routine properly. When it finishes, I expect it to be
browsable, especially after I make sure the expiration/retention dates on
both the saveset and index saveset are set for 7 years in the future ...
I'm confused here. The man page says:
"-i Rebuilds both the media and the online file indexes from the
volumes read. If you specify a single save set with the -S ssid option,
only entries for the specified save set are copied to the online file
index. Note that for version 6.0 and later, if you have the tape
that contain the index backups that go along with the data backups, the
recommended way of restoring your indexes is to run scanner -m to
reload the media database entries for the index and data backups.
Once that is done, you should run nsrck -L7 -t date <clientname> to
recover the index for the client as of the time of the backups on the
tape. This will roll the index entries for that time back into the
index. However, if you have tapes for which there are no index backups,
then you will need to use the -i option to reconstruct the index
entries."
The first thing you tried (unintentionally since you meant to specify
-'i') was '-m' and then the nsrck -L7 command, right? This is exactly
what the man page suggests. But the last sentence in the man page has me
confused wherein it says: "However, if you have tapes for which there
are no index backups, then you will need to use the -i option to
reconstruct the index entries." Don't you have a backup of the index? If
so, why would you need to use the 'i' option? Why would the '-m',
followed by the 'nsrck -L7' not have worked, at least logically? We know
it didn't, but is this expected given your scenario? Why is the '-i'
necessary in this case? Just asking. I don't know.
