Problem to use DAT40 Storageworks with a DL380 G2

[Erick Vieira de Menezes]

Hi, Everyone.

I´m new here and I´m having problems getting my DAT40 to work properly with my server. I am running Linux Fedora 6. I have tested the tape device on the server with windows 2003 and Arcserver, where everything worked perfectly and I was able to write and restore the data on the tape.

However, on the Linux box, I was able to install the tape drivers, but I wasn’t able to write or restore to the tape. I have looked for threads here and can’t figure what the problem is.

So, if anyone can help me I’d appreciate it a lot.

That is the dmesg, and the mt commands:

Hi Erick,

It looks as though you've probably got the tape drive hooked up to a port on the SmartArray controller. This isn't recommended. Why it should on Windows and not Linux, I don't know, but you'll save youself a lot of hassle by hooking the tape drive up to a dedicated SCSI card.

Cheers,

Rob

Hi Rob,

Thank you for help me.
Why isn´t recommended plug the tape device on the SmartArray?
So I follow what you sad and I try to connect using the rescan script that I found yesterday inside one thread here in ITRC, and the response that I receive its:

[root@bope ~]# ./rescan-scsi-bus.sh
No SCSI host adapters found in sysfs

When I plug the tape on the SmartArray, I receive:
[root@bope ~]# echo "engage scsi" > /proc/driver/cciss/cciss0
[root@bope ~]# ./rescan-scsi-bus.sh
Host adapter 0 (cciss) found.

What can I do in order to plug this tape on the scsi port and not on the SmartArray?

Cheers,

Erick
