DLT backup device

[VasBert]

Hi, When I do an inventory of the tapes, it shows the cartridge labels as it should, i.e. Slot 0 = Tape 0 … Slot 12 = Tape12 respectively.
But under the devices tab it does not show the correct info under the cartridge label, i.e. it either shows Slot 5 = Tape9 or Slot 8 = <Unknown media> etc.
I do another inventory and the report shows as being correct, but the details in the devices tab are jumbled up again.

any ideas?

We use a Quantum DLT700 backup device with a 13 tape (0-12) autochanger.

Thanks

Vas

Hi,
I have a DLT7000 with 7 tape autoloader. Operation works reasonably well except for speed. ANY network resource that gets backed up is only operating at around 20mb per min. THis is just too slow for the amount of data I have to deal with (> 100gb). Any ideas on how to increase the speed? We are using the hardware compression option.
O/S is NT 4 svc pack 6, Dell svr with 1gb RAM and dual proc. 800mhz.
Any input appreciated.
Tks
Neil

I maybe to late for you but maybe usefull for others. I'm using a 7 tape autoloader with one Quantum DLT 7000 Drive and I can have a way faster speed than that. The Autoloader is ADIC attach to a Proliant 1500 (single 166 Mhz Pentium with 196Mb RAM) Netware 4.11 with ArcServe and I can backup at an average speed of 70 mb per minutes. I don't know how to fix your problem but I'm sure the autoloader is not the problem.

Did anybody get an answer to the first question regarding unknown media?

This is what I had to do to get the autoloader to be recognized by Veritas software

IV  (If all else fails)

1.  Stop the Backup Exec Services

2.  Assuming that Backup Exec is installed in the default directory: Browse to directory C:\program files\VERITAS\backup Exec\NT\pvl.mdb and rename this file to pvl.old by right-clicking on the file and choosing &quot;rename&quot;
NOTE: Replacing the PVL.MDB will cause the loss of all media management information, including allocation date, overwrite protection periods,  <append period> s, media set information, and media statistics.  Resetting this information will cause all tapes to be placed in the &quot;Imported Media&quot; set, and will by default have an overwrite protection period of infinite.  This procedure is not recommended unless all other troubleshooting steps have failed, and should only be performed by an experienced administrator.

3. Insert the Backup Exec CD in the CD-ROM.  Search the CD-ROM [WINNT\Utils\pvl.mdb] or install files for the file that was renamed (pvl.mdb).  Copy this file to the above directory and then remove the Read-only attribute by right-clicking on the file and choosing &quot;Properties&quot; -> uncheck the box next to the Read-only attribute.

4.  Start the Backup Exec Services.  Launch Backup Exec and check the device listing in the Devices Tab.  If the device still is not listed properly, contact Veritas Technical Support for further assistance.

Actually the solution was much simplier but many thanks for your advise. I will keep your recommendation in my knowledge base.... you never know.

But on to my fix, basically I justed downloaded the latest Quantum drives for my DLT7000, stopped all Backup Exec services; loaded new drives; disabled all devices and drives within Removable Storage; restarted services and kicked off Backup Exec and re-inventory.

Thats it!!!!

Good Luck
