Ataraid-list Digest, Vol 43, Issue 9

[Fang, Ying]

Hi Tiago,

I'd like to investigate why OROM misunderstood the ISW metadata written
by iMSM. From the below info, OROM failed to detect one hard drive in
the array.

Could you run "dmraid -b" and "dmraid -n" on your system? The first one
shows the current hard drive info and the latter displays the metadata
on disks. Those may give me a clue which hard drive caused the hiccup.

I try to repair your metadata if possible. Please wait for a short time.

Thanks,
Ying
