No, it has definitely finished. The command returned to a system prompt.
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?
It is on the tape, with the saveset I wanted.
If so, why would you need to use the 'i' option?
Nsrck -L7 did *not* work, as it claimed that no index entries existed for
that client (which was true). I've since been advised that I could
have/should have? Used "nsrck -L6", and not "-L7".
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.
Beats me. :-) I know that I usually do "scanner -m", then an mminfo to
determine what order the tape(s) were written, and then "scanner -i", in
that order. I've been told (I believe by EMC Tech Support) that you *must*
run "scanner -i" in the order shown by the mminfo, else the index is not
properly rebuilt. And *I thought* that "nsrck -L6 (or -L7)" wouldn't work
to re-read an index made by some other NW server; that in the case of
using tapes from a "foreign" NW server, you have to use "scanner -i", and
not "nsrck -L6/-L7".
Perhaps that is wrong, and "nsrck -L6" would work ... not sure how, as the
system would need to have "scanner -m" on an index saveset, so it knows
what tape the index is on ...
My understanding is that you should be able to use 'scanner -m' to
rebuild the media database entry for the saveset (in this case D:\) and
then also for the CFI save set. Next, you should be able to use 'nsrck
-L7 -t date' to recover the index information. But if you don't have the
index save set on tape or you don't have the tape then you would need to
rebuild the index entries using 'scanner -i'. So if you were in that
situation then you'd just start with 'scanner -i', obviating the need to
use 'scanner -m' as a second or previous command. But you did have the
CFI save set on tape, but 'nsrck -L7' didn't work for you. I think there
is an issue when recovering indexes backed up on another server. I ran
into this one time before. See my post: "Re: [Networker] nsrck -L7 error
- help?" from 2010-03-16. It may have been similar to your problem. It's
an annoying problem that shouldn't exist. The software should be able to
work around it.
I don't see how 'nsrck -L6' would help, though? That doesn't recover an
index. It's just the highest level of checking (1-6). You can't check it
until you've recovered it. I mean, you have to have an index to check
first, and your index was initially empty, following your re-creation of
the NSR client resource, right?
BTW Is it necessary to check the index (nsrck -L6 or lower) after you
rebuilt it (scanner -i) or after you recover it (nsrck -L7, assuming
that had worked)?
