Hi DEC Unix Managers,
I have a DEC 500/333 system with a Raid SCSI controller
(KZPSC-PA). It shows up under the PCI Bus:
Bus 00 Slot 07: DAC960 Scsi Raid Controller
Running DEC Unix 4.0B
Please note that this is the first time that I ever dealt with RAID.
Well I had the bright idea of adding 2 23GB disks to the raid
controller and set them up in JBOD mode. I added the two disks (wide
scsi) to the raid controller and set the scsi id at 0 and 1.
>>>ARC
power cycle system
load diskette
selected Run a program
a:swxcrmgr
Selected Automatic Configuration
Selected JBOD
Selected Initialize Logical drive
Selected Logical Drive 0
Selected Logical Drive 1
Selected Start
(Then I went home... it took a long time)
Well since I didn't know what these disks would be called, I decided to
boot the system with genvmunix to see how the system would configure these
disks. May have been a mistake, on boot it gave:
xcr0 at pci0 slot 7
xcr_logger: XCR_ERROR packet
xcr_logger: cntrl 0 unit 0
re_getdrive
Cmd should always return good status
Hard Error Detected
Active XCR_COM at time of error
xcr_logger: XCR_ERROR packet
xcr_logger: cntrl 0 unit 0
re_getdrive
Cmd memory lost
Possible Software Problem - Impossible Cond Detected
and it repeated for cntrl 1 unit 1 also.
I then made things worst by assuming the these new disks may have been DOA
and switched them to the regular scsi bus and did the disklabel and newfs
to verify them. They were okay.
Now I can't get swxcrmgr to work at all. It gives an installation
aborted message and show original state as optimal and current state as
failed.
1). How do I back out from this problem?
2). Should this have worked at all? If yes, where did I go wrong?
3). Perhaps I should buy second scsi controller and forget using the raid
controller in JBOD mode?
Thanks in advance,
