Hi,

RELENG_4_4:

I get some errors:
(da0:ahc0:0:0:0): READ(10). CDB: 28 0 0 f1 2b 50 0 0 c 0 
(da0:ahc0:0:0:0): MEDIUM ERROR info:f12b59 asc:11,0

They are from 9:44 to 11:20 in the morning.

I tried to issue "camcontrol defects da0 -f block -G", but I get
"camcontrol: Error returned from read defect data command".

da0 at ahc0 bus 0 target 0 lun 0
da0: <IBM DDRS-39130D DC1B> Fixed Direct Access SCSI-2 device 
da0: 80.000MB/s transfers (40.000MHz, offset 15, 16bit), Tagged Queueing Enabled
da0: 8715MB (17850000 512 byte sectors: 255H 63S/T 1111C)

What did I wrong with camcontrol and what can I do to get rid of those
errors? Do I have to replace the disk or the cable?

Bye,
Alexander.
