Problems with second SCSI controller

Fri, 2 Oct 1998 12:13:59 -0700 (PDT)

We have a dual PPro box here with two SCSI controllers, and are having
trouble trying to use a disk on the second controller. There's lots of
users so it's the usual Unix thing of not wanting to bring the machine up
and down without a clear idea of what to do...

Anyone have any experience with this ??

We have 2.0.32 and get:

The system's been up long enough that all the boot time probe info
has fallen off the end...

Does this look like a real hardware error or a misconfig ?
I assume that the driver supports multiple cards else things
wouldn't have gotten this far.
