MSL5000 in SLES9 not working

[James Specht]

OK I have lots of information here and hope someone will be kind enough to push me in the right direction to solve this problem. Basically I have an MSL5000 tape library with one (1) robotic arm and four (4) tape drives in it. We recently moved the MSL5000 into our SAN and would like to have a SUSE SLES9 32bit system run the library. The server hardware is a DL380. Once the zoning was setup we saw the robotic arm and the four tape drives no problem. I tested moving the robotic arm and that works fine. What I cannot do is read or write from any of the drives. It looks like the /dev/stX (0-3) are not actually linked to the /dev/sgX devices, even though sg_map shows they are. I feel like I am missing something big here. Below is output from the following commands;

1. sg_map
2. cat /proc/scsi/scsi
3. lssg
4. cat /proc/scsi/qla2xxx/0
5. cat /proc/scsi/qla2xxx/1
6. tapeinfo -f /dev/sg0

If I try to do anything to /dev/st0 through 3 the command just hangs.

Any help would be greatly appreciated!

Jim,

You have probably solved your issue here. If you haven't, here is what I am seeing:

My 4 SDLT320 drives installed in an ESL 630e library gave me the same problem on SLES9 running on a DL380G4. I see almost exactly the same results from sg_map, /proc/scsi/scsi, and /proc/scsi/qla2xxx/0. I was frustrated until I tried to tar cvf something to one of the drives. I was surprised to see that tar would write to the drives. If I run scsi_info /dev/sg0, I see immediate results. In my case, the st driver is able to write to the drives, but the sg driver only works for getting info about the drives. I am using Legato Networker 7.2.1.

Mostly, I am just glad to see that someone else is using SLES9 to backup to a fibre-attached tape library.

HTH,

Ryan
