Catalog old media - loading media/queued

Created: 07 Nov 2012 | 7 comments

Hi,

I've recently replaced my Backup Exec Server and my LTO4 autloader for an LTO5 autoloader.

I'm trying to catalog some old tapes to look for some files which a user is looking for.

I've put the old media in to the LTO5 autoloader, run an inventory job - it detects the media (but doesn't read the label) and sticks it in the retired media media set.

When I then try and catalog the tapes (the backup job would have spanned three tapes) it just sits for literally hours (15+) and alternates between "Queued" and "Loading Media" and the tape keeps loading and unloading from the drive.

What am I doing wrong?

I've still got the old LTO4 autoloader... so my next step is to try that... but I'd really rather not as it'll involve mucking around with SCSI cards.

What are the tapes?  If they are LTO2, then they cannot be read by the LTO5 drive.

If they are LTO3 or LTO4 tapes, then I would suggest running the SCSI tracer and doing an inventory job.  Are there any errors in the inventory job log?

If you find this is a solution for the thread, please mark it as such.

They're LTO4 tapes - so should definitely be ok to read on the new drive.

How do I run the SCSI tracer?

Using tracer - http://www.symantec.com/business/support/index?pag...

Try deleting the media from the retired media set (it will not delete any actual data from the tape) & retry inventory & catalog...before catalog, from tools-options-catalog, uncheck the option for use storage media catalogs...

Magic - thanks very much for that.

I'll give it a whirl on Monday - not in the office until then!

I've tried deleting the media from the retired media set and retried the inventory and catalog... no luck.

I've also tried the various options under the "tool-operation-catalog" menu.

What should I be looking for the in the SCSI-tracer logs?

In the SCSI tracer, look for any events in the "check" column, then see what is down in the Sense/ASC/ASCQ lines for that event.  Hopefully something will leap out at you as being obviously wrong.  Not all "check" conditions are truly bad, as some are routine/expected.

If you don't see anything bad in the tracer from an inventory job, then it must be something that BE actually  read from the tape that made it put it in the "retired" media set.  I wouldn't worry about trying to catalog until you get inventory working good and can keep the media out of "retired".

Here is an example of a command with an interesting (put appropriate) "check" condition.

Well - I've run the SCSI tracer tool while doing an inventory job - the tape labels aren't read and the media gets put into "retired media". I've looked at the SCSI tracer logs but I can't see anything obvious - these are the only bits that have something in the check column:
