Hi list, hope someone can help me, I have a pretty odd problem.

I recently installed NetBSD 3.0 on my aging Compaq Proliant 1600 server
- everything seems to be working beautifully and I'm extremely pleased
(just get that out of the way first - top job, best OS I've ever used!).

What is strange though is that the box has 2 SCSI controllers, one of
which has the machine's 6 hard disks on. They are all correctly found accor=
ding=20
to the dmesg output:

Notice sd5 in the list there.

With the exception of sd0 (which contains the NetBSD installation), the
other disks are all formatted with one large ext2 partition.

I can happily do disklabel sd1-4 and mount_ext2fs sdXe /diskX to mount
the disks and use them just fine.=20

My problem is that no device nodes are created for sd5 and even if I
try to manually create them with mknod, I get "Device not configured"
when trying to mount.

# ls /dev/sd*

/dev/sd2p /dev/sd3f /dev/sd3l /dev/sd4b /dev/sd4h /dev/sd4n

Since the first 5 disks work perfectly is there some sort of arbitrary
limit on the number of disks per SCSI controller or something?

If I boot from a Linux LiveCD the 6th disk is ok and mountable.

It's not a big deal to me as I can swap it for sd2 (which isn't used
at present anyway) - just thought this was odd enough to report.

Cheers!

Rob
