Hi All,

quick query.. not sure it's o/s [NetBSD 1.4.2] or h/w [DEC alpha 5000 with NCR
SCSI card] related...

basically I started getting the error below, so i assumed a disk was dying,
therefore I [feeling brave & not having down-time available]...

- umounted it
- physically pulled the disk
- inserted a new disk
- since it's the same as the other disks, i tried:
     - 'disklabel sd4 > image.bin'
     - then, 'disklabel -R sd5 image.bin'
- at this point was was expecting to then do a newfs etc & mount it...

but instead it got the other error below. Throughout this all other disk on the
same SCSI bus & backplane contiune to be fine. Am I asking to much of the h/w
here without using a RAID controller ? [I have one but there is no NetBSD driver
for it] or am I just being stupid ?

any thoughts or comments invited.
