Hello,
I installed an Adaptec 2940U2W SCSI card today on the machine running
3.2-RELEASE and ran into a couple of problems. Here is the connection scheme:
attached to a seagate Sidewinder
tape drive (drive is terminated)
|
|
68pin internal wide ultra
connector
68pin internal ultra 2 connector
|------------| |---------------|
| -----------------------------------------------------------------------
|
|
--|
| |---------------|
| 50pin internal ultra connector
| connected through the internal-to-external
68pin external cable to a RAID array (the RAID is terminated).
ultra 2
connector
ultra 2 connectors are not used. On the boot, the card detects both devices. First problem:
During the boot, I get an error:
Waiting 15 seconds for SCSI devices to settle
(probe0:ahc0:0:2:1): parity error during Command phase
SEQADDR == 0x15c
SCSIRATE == 0x95
panic: RAM parity error, likely hardware failure.
syncing disks...done
If I disable parity using the scsi card setup utility, the errors go
away, but I am not sure that disabling parity is a good thing.
Before, the same setup was used with Adaptec 2940 Ultra SCSI adapter
with the parity enabled.
Second problem: if I boot with the parity off and try to mount a partition from a RAID,
I get the message:
# mount /dev/da0s1a /mnt
mount: Device not configured
as if the devices weren't compiled into the kernel (I am using a GENERIC kernel).
dmesg shows:
<skip>

da0: 40975MB (83918593 512 byte sectors: 255H 63S/T 5223C)
The SCSI card and the disk da0 are both recognized, and if I move the disk da0 to the old
computer with the old SCSI card and the same kernel, I can mount the partition.
Do you think the card could be defective? I have wasted a whole day on that
thing and ran out of ideas -- any advice would be very much appreciated.
Thank you!
