Hi list,

I've been searching the list archives for an answer to my question,
found similar stuff, but not exactly this one.

So.
I installed FreeBSD on a box these days, having these (brand new)
SCSI disks:

da0: <IBM-PSG DDYS-T36950M  F S94S> Fixed Direct Access SCSI-3 device
da0: 160.000MB/s transfers (80.000MHz, offset 63, 16bit), Tagged Queueing
Enabled
da0: 34715MB (71096640 512 byte sectors: 255H 63S/T 4425C)
(da1 is exactly the same)

AWRE and ARRE is 1 for both disks.
The controller is an Adaptec 29160 Ultra160 SCSI adapter.

These error messages keep on coming:

(da0:ahc0:0:0:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da0:ahc0:0:0:0): RECOVERED ERROR asc:5d,0
(da0:ahc0:0:0:0): Failure prediction threshold exceeded
(da1:ahc0:0:1:0): READ CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0
(da1:ahc0:0:1:0): RECOVERED ERROR asc:5d,0
(da1:ahc0:0:1:0): Failure prediction threshold exceeded

and

(da0:ahc0:0:0:0): WRITE(10). CDB: 2a 0 4 3c d9 3f 0 0 1 0
(da0:ahc0:0:0:0): RECOVERED ERROR asc:5d,0
(da0:ahc0:0:0:0): Failure prediction threshold exceeded
(da1:ahc0:0:1:0): WRITE(10). CDB: 2a 0 4 3c d9 3f 0 0 1 0
(da1:ahc0:0:1:0): RECOVERED ERROR asc:5d,0
(da1:ahc0:0:1:0): Failure prediction threshold exceeded

I get them when trying to access the drives after some 10 minutes of
inactivity. They never come when the disk is active, or was active in
the last ~10 minutes. (btw APM is disabled. Totally.)
They come in pair for target 0 and 1 since I use vinum RAID-1 :)
Had them before as well, but not in pairs.

Some messages were produced under OpenBSD as well, i can supply them if
needed.

Any help is highly appreciated, thanks in advance.

bye,
Roland
