I recently installed a dual ultra320 card into our V880. (Solaris 8,
fully patched). After turning it on and doing:

ok> probe-scsi-all
(saw it)
ok> boot
....
/usr/sbin/devfsadm
format (see the disk)
newfs
etc.
In other words, no problem with that disk at all.

Today I was trying to get the USB working and ran a script from Sun
called "usbconfig.txt", which caused the system to shut down. When
it went into the maintenance level I also changed ONLY diag-level via:

/usr/sbin/eeprom diag-level=min

and rebooted. This thankfully reduced the boot time from nearly half an
hour (which was due to installing the most recent openboot recently) to
just a couple of minutes.

So it comes back up, and the new disk is GONE. It doesn't show up in
"format", running "devfsadm" doesn't bring it back. cfgadm -al
shows the c3 controller but it is

c3 scsi-bus connected unconfigured unknown

The other scsi controller is configured and it's one device (a tape
drive) shows. So I tried:

cfgadm -c configure c3

but that just caused a bunch of errors and warnings in the
/var/adm/messages, like this:
Nov 21 11:19:23 gec krtld: [ID 995402 kern.notice]

/platform/sun4u/kernel/misc/sparcv9/sbd: undefined symbol
'sbdp_portid_to_cpu_unit'

No idea why it is trying "sdp" since this is supposed to use "mpt"

prtdiag shows this:

I/O PCI 9 A 8 66 66 1,0 ok
scsi-pci1000,30.1000.10c0.8/disk+ LSI,1030
I/O PCI 9 A 8 66 66 1,1 ok
scsi-pci1000,30.1000.10c0.8 LSI,1030

so Solaris does see the controller. I think maybe it sees it twice
because it is a dual channel controller.

It's a Storcase JBOD and their software (infomon) shows everything
working normally.

What do I have to kick to get this system to see the disk again?
Preferably without having to do a probe-scsi-all manually at each boot.
