Hi,
I have an XP1000 with Tru64 v5.1 that is giving me some strange results.
Here is a listing of the devices connected to the XP1000 from hwmgr
HWID: Device Name Mfg Model Location

4: /dev/kevm
45: /dev/disk/floppy0c 3.5in floppy fdi0-unit-0

64: /dev/disk/dsk8c SONY SMO-F551-DD bus-1-targ-6-lun-0
58: /dev/disk/cdrom0c COMPAQ CRD-8322B bus-2-targ-0-lun-0
59: /dev/disk/dsk5c COMPAQ BD009222C7 bus-4-targ-0-lun-0
60: /dev/disk/dsk6c IBM DDYS-T36950N bus-4-targ-1-lun-0
61: /dev/disk/dsk7c SEAGATE ST318436LW bus-4-targ-2-lun-0
66: /dev/disk/dsk9c SEAGATE ST3146807LW bus-4-targ-4-lun-0
65: /dev/ntape/tape2 QUANTUM DLT7000 bus-4-targ-5-lun-0
There are a couple of things wrong with this list
(a) I have 2 Seagate ST3146807LW on the same scsi bus, one with target id=3
and one (the one in the table above) with target id=4. The second
ST3146807LW is recognised at the prom level and can be seen as DKC300, the
targ-4 can be seen as DKC400, and the other disks on bus-4 have the
appropriate DKC listing.
(b) the cdrom on bus-2 is not reported at the prom level (ie >>> show dev)
(c) there are 3 buses reported at the >>> level, namely DKA (maps to bus-0
above), DKB (maps to bus-1) and DKC (maps to bus-4). ie there is no mappings
for bus-2 it would appear at the prom level.
Somehow the adding of scsi cards has stuffed things around, and I'm not sure
what to do. The original idea was to have fast devices all on the one scsi
bus and slow or slower devices on another bus. The MO device is scsi-2 and
has a centronics 50 pin connector, the rest have honda 68 pin connectors.
Ideally the DLT7000 should be on a separate bus, or on the same bus as the
MO. The SDT-10000 is a retro-fitted DAT DDS4 internal drive using the
supplied 68 pin ribbon bus. The original dat was a DDS3 which had a 68-50
pin special connector.
The basic problem at the moment is to get the second 140gb seagate
(ST3146807LW) recognised by the system. The second is to get the CDROM
recognised at the prom (>>>) level, so I can update the firmware and also
update the OS.
I'm a bit fuzzy on this but I believe some of the Compaq/DEC equipment had
limitations on the number of scsi buses or scsi cards that the
hardware/firmware could support. I'm not sure how it all works, but I have
had problems adding scsi cards to Personal Workstations, to the extent that
once the card was added the machine refused to boot, or had problems during
the boot.
Options:
(a) I have access to a couple of dual scsi cards that have micro 68pin
connectors, I was going to pull one of two of the scsi cards out and replace
it with the single card. I was going to put all the disks on channel 1 and
the MO and the disk drive on channel 2 using a 68 to 50 pin converter to for
the MO drive. I believe there that the PCI slots in the XP1000 are separated
by a bridge, and I'm not sure where which PCI slot to put the card in to
maximise my chances of getting this thing to work.
(b) pull the scsi card out that is currently supporting the MO drive and see
if that fixes the problem at the prom level.
(c) something else???
Hope someone out there has some ideas on which way I should jump.
Dennis
