LinuxQuestions.org - Hp Ultrium-2 Scsi Tape Drive Problem

Hello.

I'm having huge problems with my Ultrium-2 tape drive at work. BIOS and Linux recognise the device normally and the info they gather is correct.

I am using tar/gtar to write and read files. I tried writing single file on tape, listing all files on tape, recovering files from tape and everything works normally.

However! Every time I try to backup a folder from my RAID it stops after a while. This always happens after a minute or 2. The tape writer simply stops (saying IDLE on display) and the console window stops for a while, then I get

Code:

tar: /dev/st0: Warning: Cannot close: Input/output error

Prepare volume #2 for `/dev/st0' and hit return:

and it's asking for volume 2. But the tape is definitelly not full and after inserting new tape I get "cannot open /dev/st0" error message. In /var/logs/messages I get following entry:

Code:

"kernel: st0: Block limits 1 - 16777215 bytes."

Anyone knows or suspects what could be the problem? Do I need to post any other error info maybe? I've tried different distributions already: Fedora 6, OpenSuse 10.2 and now I'm on CentOS 4.3

Thanx.
