Hello,
I've having trouble getting my new Adaptec card working in linux. I
have installed the card, attached two blank drives, which I want to use
in a RAID 1 mirror. (sda & sdb)
I have been rather dissapointed to discover this is not a real RAID card
but mostly software RAID, and the tool I should use is dmraid. The
supplied linux driver is useless as it's a ".o" not a ".ko".
I have setup the array in the HostRAID BIOS using the "build" option,
even though the drives are blank.
The array did appear at this stage, but only on one drive in a degraded
state.
I keep getting repeated messages from dmraid stating:
"ERROR: asr: Invalid RAID config table checksum (0xF36 vs. 0x805) on
/dev/sda"
however google has no info on this error.
diag using dmraid returned the following:

I then tried building the array again in the Adaptec BIOS, this time
using the CLEAR array option. The BIOS shows the array status as
"OPTIMAL". However now neither drive appears to be in the raid set:

Anyone got any ideas what on earth is wrong?
