thanks, this was suggested, and got me nowhere.

Unless I missed a step somewhere, but lsmod did return st* in the list.

Also, you could also try adding:

options scsi_mod max_scsi_luns=128

to your /etc/modules.conf file. You'll need to recreate your initial
ramdisk after that as well.

I'm using ubuntu hoary. However finding the same as above. Googling
hasn't got me far. Any suggestions, hints, ideas, relivant urls, abuse
great fully received.


With all due respect to the distro you're running, you'll need to get
the actual IBM serverraid driver from IBM and stick that in your kernel
to make all of your problems go away, rather than using the kernel's
native ips driver.

For that you'll need a compatible distro such as RHEL, or at the very
least one that can be convinced that its kernel is RHEL compatible,
such as centos.

[SLUG] missing scsi tape drive

2005-07-16 Thread ashley maher 
I have an IBM xServer 226, with ServerRaid. dmesg does not detect the
scsi tape drive. More /proc/scsi/scsi finds the existance (ie model
number no details like it knows something is there not a clue what) of
the drive but not much else.

There is no st0, nor indication of the tape drives existance.

From the Red Hat Web Site:

quote
First, ips is the driver for IBM's ServeRAID controller. Every once in a
while, the reset request will take the tape drive offline. We have
experienced this problem on a number of systems with ServeRAID cards.
Having a dedicated scsi controller for the tape drive seems to have
eliminated this problem.
