All,
I recently purchased a used KZPSC controller with the intent of using it
on my AlphaPC 64 system under Tru64 5.0.
By plugging the board into an Intel box, I was able to upgrade the
firmware to v2.49 and configure a JBOD arrangement using an IBM brand SCSI
drive. Once this was transferred over to the Alpha and the kernel rebuilt
to support the 'xcr' device, I was able to partition the disk (with UFS
filesystem), mount it and access it normally.
Next, I wanted to migrate my boot partition from the existing primary
drive (on a clone NCR 53C875 controller) over to the RAID controller. In
the process, the boot partition would change from an AdvFS filesystem to
UFS. The files were copied using a pair of GNU 'tar' processes (moves
special files, links, etc. properly).
The admin guide for T64 suggests that the hardware database will still
want to regard the drive as the device it was under the original boot
environment - /dev/disk/dsk3a, 3b, 3g (root, swap, usr). I modified fstab
and sysconfigtab accordingly and erased links from /etc/fdmns/* to the old
AdvFS device.
Disk label was written to the JBOD drive using:
# disklabel -Rr -t ufs /dev/disk/dsk3a disk3 rz
where 'disk3' was an ASCII save of the partition information.
>From the console, a boot starts off fine by:
>>> boot dra0
However, immediately after initializing the NCR controller the process
fails with a series of fast-scrolling messages in the form:
XCR_COM
re_getdrive
Cmd should always work
...
then dies with a message that it cannot mount the root filesystem.
I see these messages during a normal (successful) boot as well, but
everything ends up working properly.
I must be overlooking something in the configuration, but what? Is the
driver complaining because I don't have an actual Storageworks shelf
connected to the controller?
In desperation, I tried to make a new install from the distribution CD,
but the kernel fails to recognize the RAID controller or the attached
device! I only get the option of targeting the two drives attached to the
NCR controller.
Any help appreciated at this point.
