U-Users,
I've installed 6.06 LTS LAMP server on a machine with an Adaptec
2020ZCR RAID5
controller. The RAID array is on channel 0 and a Quantum DDS4 DAT Drive
is on channel
1. I've run the Adaptec setup 'detect' software to make sure that the
SCSI BIOS recognizes
that the DDS4 drive is attached.
I went to the Quantum site and followed the directions for Linux
install including running
'modinfo st' which returns...

vermagic: 2.6.15-26-server SMP 686 gcc-4.0
depends: scsi_mod
srcversion: 139CFBF9AEE4AE854005025
parm: try_wdio:Try direct write i/o when possible (int)

parm: max_sg_segs:Maximum number of scatter/gather segments to

parm: buffer_kbs:Default driver buffer size for fixed block
mode (KB; 32) (int)
... but my dmesg output contains only
st: Version 20050830, fixed bufsize 32768, s/g segs 256
... and not the "attached scsi tape device" kind of detail I was
expecting.
The st device files do not show up in /dev and MAKEDEV -v returns...
/dev# MAKEDEV -v st
create st0 c 9 0 root:tape 0660
create nst0 c 9 128 root:tape 0660
create st0l c 9 32 root:tape 0660
create nst0l c 9 160 root:tape 0660
create st0m c 9 64 root:tape 0660
create nst0m c 9 192 root:tape 0660
create st0a c 9 96 root:tape 0660
create nst0a c 9 224 root:tape 0660
... so I created the character special files with mknod and then ran
stinit which returns...
/dev# stinit
Initialized 0 tape devices.
At this point I'm stuck any suggestions welcome.
Thanks,
Steve
