Fedora core 3 tape library on 5i controller

Kent L. Nasveschuk — Sat, 23 Apr 2005 07:25:09 GMT

Hello,
I'm trying to get my Sony tape library, LIB-152e/a2 to run on Fedora but it's not recognized when attached externally on the 5i controller that comes with an HPDL380. Anyone have similar experiences?

The stock Fedora kernel and most recent update both have CONFIG_SCSI_MULTI_LUN=y built into the kernel yet I still cant't see anything under /proc/scsi/scsi. Also, according to manufacturer, the changer and drive have to have a unique scsi id on the bus, which leads me to believe that it's not dependent on LUN support anyway.

Should I move this off the 5i raid card onto it's own controller?

Any suggestions, experiences would be appreciated. Thanks

There's also the kernel option for tapes on the cciss based controllers. Make sure that's on.

If that still doesn't work, then yea. Try it on it's own controller.

The config also has:
CONFIG_CISS_SCSI_TAPE=y

Guess it needs to be on a separate controller.

Hello again,
I've finally got my tape library running on an FDC3 machine with all updates. The problem has always been trying to get the tape librar recognized on the Smart Array controller of a DL380. For the benefit of anyone experiencing the same problem, I'll explain what I've done to fix it.

Original system:
HP DL380 G3
Smart Array 5i controller
Fedora Core 3 with all updates
Kernel 2.6.11-1.14_FC3smp
Sony LIB-152e/a2 AIT 2 tape library with barcode scanner

Test system:
Standard garden variety whitebox
Adaptec 2940UW scsi card
Fedora Core 3 with all updates
Kernel 2.6.11-1.14_FC3
Sony LIB-152e/a2 AIT 2 tape library with barcode scanner

Modification to grub.conf to get it running:
1) kernel /vmlinuz-2.6.11-1.14_FC3smp ro root=/dev/VolGroup00/LogVol00 rhgb quiet pci=noacpi
(without the pci=noacpi library is recognized but unusable)
2) modprobe sg
I don't know quite where to put this, didn't work in modprobe.conf unless I need a specific alias. It did work when I put it in rc.local.

The only reason that I haven't moved the Adaptec card to the DL380 is that it is the older 5v version. The newer cards are 3.3v and have an indentation so you can't mix them up. In the process of procuring one.

Anyway mt and tar commands work on /dev/nst0, /dev/st0 and mtx works great on /dev/sg0 and /dev/sg1

Confirmed that the tape library won't run attached to Smart Array controller 5i on FDC3. Get another scsi controller to run it on.
