SDLT 320 Tape drive issue

Hi, We have a SDLT320 Tape Drive that we backed up a SAN Databse connected to Solaris Box,  The backup took 8 hours, which was ok,  However, the restore is really slow (800kbps) which is about 8 times slower than anticipated, the logs does not show any issues with regards to corrupt date of anything, it is just really slow, Would love to know what your thoughts are on this and if there is a solution for this slow transfer speed
Regards

SOURCE: Using SDLT cleaning Tape

When the drives Clean LED comes on, install a "Universal" LTO Cleaning tape, as these drives do not need routine cleaning. Only ever clean a LTO drive when it's requested, as the cleaning media itself is more abrasive than a standard tape.

SOURCE: hi, Guru

Hi,

Tape getting struck in media library may not be because of the backup application. Move the media out manually. While filling in the media slots make sure you leave a couple of slots free to avoid the srtuck scenerios..

Please come back and rate my solution if it turns to be helpful for you.
Thnx :)

How to allocate media with ntbackup


  1. Valueloader should have "SEQ" on front screen.
  2. Insert media into Valueloader

NTBackup will NOT see individual tapes, but treat the SDLT320 drive as a stand alone with one big tape, and the Valueloader will automatically change tape, in sequence, until the backup is done.

This is the major difference between a "Autoloader" (Sequential Mode) and a "Library" (Random Mode).

In Sequential Mode the robot (or Medium Changer) is hidden from the OS, thus only providing a tape drive. The autoloader is smart enough to see incoming data and will move Tape1 into the drive. As the media fills, the autoloader will swap media on it's own. By the time the backup is complete, whether it be one or all 8 pieces of media, Windows has no clue that it's data crossed multiple pieces of media.

In Random mode, the library is dumb and will do nothing on its own. It's told by software (i.e. Backup Exec, CommVault, etc.) when to move a tape into the drive and which tape to move!

The advantage of using Random Mode is that software runs the show and media is effeciently managed. Restores are much quicker as the exact tape a file is recorded on can be directly loaded and extracted, vs. (worst case in Seq. mode) having to go through each tape, in sequence, before getting to the file that could be on that last tape (think hours!).

I have a Quantum SDLT 320 drive in a Dell 2800 server that has the yellow attention light stuck on. It is performing backups successfully in Veritas and giving no errors from Veritas or anywhere else. Can...


Sounds like it may be the cleaning light (far right)

You need to use a cleaning tape in the drive (they do expire after either 20 or 40 uses so use a brand new one to be sure)

That should clear the light. If it comes back on after another backup then try using the cleaning tape again and then a brand new tape for the backup.
If the light comes on again then the drive will need to go for repair as the head is knackered.

Try www.tape-drive-repair.com for this as they are pretty good price wise and also offer a 1 years warranty on their drives and repairs

Quantum ATL SuperLoader


If you cannot physically load a tape into the drive it is a hardware problem and the drive requires service. It is not a software problem.

Of course, the library could already have the maximum tapes it can hold. If this is the case then eject a tape from the library to make room for the tape you want to add.

I hope this helps.

My Drive will not eject the tape


Turn off the tape drive. (Switch in the back of the unit. Wait 2 minutes and then turn unit back on. Tape drive should issue a write data command and then rewind the tape. After rewind completes the tape should eject. If it does not eject after rrewind completes than try holding the eject button for 5 seconds to attempt a "force eject"

Note: Do not repeatedly press the eject button as this can cause damage to the tape and the tape drive.

Stops during boot


First of all the DS20 is an Alpha box not a VAX. The problem here is usually an adress conflict. These tape drives are usually device 500. Try placing the drive onto a different controller card. That should resolve the problem.
