Legato 7.1.2 - Tape list in Legato incorrect

Post by michael.mc » Wed, 12 Jul 2006 18:31:42


Hi all, new to this forum as you can see but I would like to ask i
any of you have come across this before

Basically, Legato inventory is showing 17 tapes as being in the tap
robot yet we have confirmation that they are not. We have done al
the usual checks & currently think it my possibly either be
Silo issue or a Legato Tape Library issue

The tapes in question have been located in offsite storage. Now, w
have the option to take them out of the cycle but that would defea
the object as this is a problem that may well occur again. So it'
better to find a solution now

Does this problem sound familiar at all? Is there anyone here that ma
be able to help

So when you run an inventory, networker still shows the same tape list?

Is this truly a silo or a normal SJI library. I'd run
/usr/sbin/sjirdtag <library> to get its internal list of tapes. After
running an inventory, the networker list and that list should be the
same.

Does Networker now keep an "on-site status" or something like that?
Some years ago when I looked at the major players in the enterprise
backup "space", Netvision's Netbackup (soon to be bought by Veritas) had
an add-on product that allowed for "vaulting" tapes outside the robot or
"on-site" storage. I ended up writing a vaulting system to track when
tapes were removed from the robot and sent to the off-site storage
vendor (about 60 tapes daily).

I'm not exactly sure what you're thinking of specifically, but I think
it has always had one (at least as far back as 4.x). However it's not
tied into a vaulting product like NetBackup offers that would actually
help script the manipulation.


Networker has a "location" field in the media database. Media found in
a library has the field set to that library. Media withdrawn has the
field blanked. Otherwise the field is available to the user via
'mmlocate'.

That's the sort of feature I used to do the vaulting system on Backup
Express (Executive Software). The key thing I had to be able to do was
access and change fields in the tape database from the command line. I
never got the chance to look at this with Legato.

The biggest problem these enterprise backup utilities have is that many
of them keep the catalog as a monolithic file or even as set of files
that has to be "compressed" periodically. During that process, the
backup product didn't run and the compress couldn't be interrupted. For
the large site I was at, the compress was talking 8+ hours, which ran
into scheduled backup time on weekends. The vendor never did fix this
problem while I was there even though my boss was on the phone with
their head of engineering almost weekly for a status on it. Ultimately,
I think that's one of the reasons it was pulled out of production. It's
not a good thing when you find out your site is the largest user of the
product, even in development.

At the time the company was making their buying decision, Legato didn't
even bid on the RFP as the amount of data being backed up was to much
for them (e.g. multi-Terrabytes a week). Last time I used Legato
(1996?), their catalog file couldn't be greater than 2GB, but that might
have been a restriction of Solaris 2.5.1.
