We're trying to set up a Dell 2950 with Slackware Linux 11 and Bacula 2.2.6.
The tape library is a Dell ML6020 with 4 IBM Ultrium TD4s and 128 slots.
These are SAS drives using the Fusion MPT SAS Host driver 3.04.05 driver.
The kernel is 2.6.23.
dmesg shows that the library (ch0) and all four drives (st0-st3) are
recognized, but /dev/ch0 does not exist and only /dev/st0 and /dev/st1
exist. Please see the attached dmesg output:

I have built mtx 1.3.11 and tried to run loaderinfo:
[EMAIL PROTECTED]:/usr/src/linux# loaderinfo -f /dev/ch0
cannot open SCSI device '/dev/ch0' - No such file or directory
And you can see st2 and st3 are MIA
[EMAIL PROTECTED]:/usr/src/linux# ls -l /dev/st*
crw-r----- 1 root disk 9, 0 1994-07-18 09:05 /dev/st0
crw-r----- 1 root disk 9, 1 1994-07-18 09:05 /dev/st1

lrwxrwxrwx 1 root root 4 2007-11-27 01:52 /dev/stdout -> fd/1
[EMAIL PROTECTED]:/usr/src/linux#
Any ideas why I am seeing this behavior?
