Disk problems?

I have a 3ware (AMCC) 9500S-4LP RAID card and 4 disks in 2 Mirror 1 arrays:
Unit 1: 2 x 80 gigs
Unit 2: 2 x 400 gigs
Under windows this was working fine. Both disks where "healthy" and running
(I could test this by unplugging one or the other):
Under FreeBSD though, it says it's not working:
May 7 13:57:37 fire kernel: twa0: INFO: (0x04: 0x000B): Rebuild started:
unit=0
May 7 13:57:37 fire kernel: twa0: INFO: (0x04: 0x000B): Rebuild started:
unit=1
May 7 13:57:48 fire kernel: twa0: ERROR: (0x04: 0x003A): Drive power on
reset detected: port=0
The rebuild message is fine, but keeps getting "Drive power on reset
detected: port=0"
In the 3ware BIOS, it shows all drives as "active" (ie. powered on and
connected), so don't know why the kernel thinks it's powered down? Does it
mean something else?
If I just "wait" for about 20 minutes, the drives start rebuilding:
Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache
AVrfy
------------------------------------------------------------------------------
u0 RAID-1 REBUILDING 37 - - 74.4951 OFF OFF
u1 RAID-1 REBUILDING 13 - - 372.519 OFF OFF
(it's in Unit one above, 37% complete). So even though it's getting this
"Drive power on reset detected" it eventually rebuilds it's self. ?
Any ideas what this message means? I thought it was an error, but seems
fine since it's rebuilding it's self. ?
Thanks.
