Yesterday I installed a new SCSI adapter card into our Alpha 4100 (Digital
UNIX 4.0E) which is attached to a new HSZ70 disk array that we purchased.
When I do a "show device" at the console mode prompt it can see all the new
drives. When I boot into UNIX, the diskconfig utility does not see the new
drives. I booted the system with the generic kernel "genvmunix" and when I
attempted to do a bcheckrc to mount file systems I need to do a doconfig, I
get error messages saying that the older file systems is invalid or cannot
be open and it can't run fsck on anything nor mount any filesystems in the
/etc/fstab. Because of this, I am not able to do a doconfig to rebuild the
kernel off the generic kernel. I tried to rebuild the kernel of the current
production kernel which worked but the newly generated kernel still did not
see the new drives on the added SCSI adapter. I then tried to boot of the
generic kernel and just mount /usr and /tmp which are advfs which worked but
the new kernel I built failed at the "bcheckrc" stage again and file systems
failed to mount. Another problem I had is that I cannot mount root as advfs
in single user mode since it is already mounted. So at this point I am
running off a backup kernel and UNIX still cannot see my new drives. It
seems like the generic kernel can see the new drives but it chokes on the
older drives and the current production kernel just can't see the new SCSI
card and it's new drives. I don't think it's a hardware problem since it
can see the new devices at the console mode prompt.
The SCSI card I added is installed at the very top. I think what is
happening is all the device names are being renumbered when using the
genvmunix and rebuilding a new kernel. Does anyone know if installing the
SCSI card at the top would do this? Since I'm out of free PCI slots, would
all the SCSI bus numbers remain the same if I move all the existing cards up
one slot and put the new SCSI card at the very bottom?
Any help will be appreciated.
