Update on problem with replacing 4 disks on an HSZ70 Raid
controller (HSZ70, 2 controllers firmware rev V70Z-0,
Hardware Rev H0Z).
We have narrowed down our problem to the new disks which we
are trying to put in the HSZ70 Raid array. There seems to be
some problem with either the type of disk or the format. I am not sure what.
I was able to move a spare disk from a different system to
the problem HSZ70 and incorporate it into one of the raid partitions.
When I try to do this with the replacement disks we bought, I get an
error, which scrolls off the screen. I cannot seem to find an errorlog
online anywhere. The error as I wrote it down is included below.
The old drives were Dec RZ1EF-CB 18.20 gb disks
The replacement drives (including the one that got used already) are
IBM DGHS18Y 18.20gb disks. Are these incompatible? Do we need to format
them somehow? Any ideas are welcome.
The error is approximately:
> set DVGRPR1 replace=DISK60100
