HP SureStore 4/40 - SCSI bus reset

[Dmitry V. Voronenkov]

We use HP SureStore 4/40 with two Ultrium drives. We use Solstice Backup (Legato networker witch Sun label) as backup software. And have two problems:

First:
SCSI bus reset occurred when software try moving tape in library.

Second:
This error occurred while Networker write on disk.

Can you help on solve this problems?

Hi there.
I think you have four drives, otherwise it would be a 2/40.
Did you daisychain the transport robot and the drives on one scsi interface ?
If ye, change the setup.
one drive --> one interface
the robot can be hokked to one drive, but nothing else.
Check the setup of your robot in your backup software as well.

Hello,

Check out this link for correct SCSI connection to a 4/40:

If you have fibre channel connection, check out this link:

Our drives attached as showed on Figure 4 in our link (two drives and robot on one SCSI controller). I try connect only one drive and robot, but with same result :(

[Vincent Farrugia]

Hello,

What firmware version do you have on the controller? You require a firmware version of 1.20 or later to support Ultirum drives.

HTH,
Vince

to Vincent Farrugia:

Library Firmware Rev: 1330
Drives Firmware Revision: E12V

Hello,

Regarding second problem... did you try to replace the tape cartidge with a new one and see what happens? It seems like a faulty tape cartidge.

to Alexander M. Ermes:
no, only two drives. Ok, 2/40.

We connect two drives and robot on one SCSI controller. HP allow this as described in

http://www.hp.com/cgi-bin/cposupport/get_doc.pl?SNI=hpsurestor19252&LC=information_storage&Tfile=lpg75041

Figure 4.

I test configuration with one drive and robot on SCSI controller, but with same result.

[Vincent Farrugia]

Hello,

Ah, now I know your config. You are daisy-chaining drives.

I doubt that will work for Ultrium drives though. Ultrium drives require a dedicated SCSI bus.

Try to connect 1 drive using the Figure 1 method, not the Figure 4 method.

HTH,
Vince

to Vincent Farrugia:

Yes, i try more tapes. As i can see, ca. 50 % tapes work with this error, some work fine(i already doubt aout this), some work with media errors on tape.

I think this is not normal.
Can you say about your tapes quality?
