We have an HSZ70 Raid controller (HSZ70, 2 controllers firmware rev V70Z-0,
Hardware Rev H0Z), which had some hardware failures last week.
We lost the cache on one of the controllers, and 5 of the disks. After replacing
the cache, and restarting the controller, we replaced 1 of the disks.
One of the raid 3/5 sets which had been in a reduced state, started
rebuilding using the new disk.
The remaining 4 disks (all on channel 6) were replaced yesterday.
Though there are still 2 Raid 3/5 sets in a reduced state (each lost 1
disk out of 6), neither is rebuilding using the new disks. I cannot figure
out how to force them to do this. The 4 new disks show up in the spare
set.
From my Digital Storageworks HSZ70 Array Controller HSOF Version 7.0
manual, I tried the command:
SET raidset-name REPLACE=DISK60100
It complained that it did not know what replace meant.
I tried setting POLICY=BEST_FIT as well as BEST_PERFORMANCE and NOPOLICY.
The raidsets are not backed up so I would prefer not to have to destroy them,
and recreate them. They are each 90gb of disk space.
I am not sure what to try now. Any suggestions would be welcome.
Thanks,
