Hi,

Just today noticed this in my dmesg on a box running a dual channel RAID car with an internal and external array

DAC960#0: Physical Device 1:3 Sense Data Received
DAC960#0: Physical Device 1:3 Request Sense: Sense Key = B, ASC = 48, ASCQ = 00
DAC960#0: Physical Device 1:3 Request Sense: Information = 00000000 00000000
DAC960#0: Physical Device 1:3 Errors: Parity = 1, Soft = 0, Hard = 0, Misc = 0
DAC960#0: Physical Device 1:3 Errors: Timeouts = 0, Retries = 0, Aborts = 0, Predicted = 0

and the SCSI device agent reported

SeqNo=41 ctl=0 ch=1 tgt=3 lun=0 Event= 1C:MLXEV_PHYSDEV_REQSENSE
at Tue Apr 27 23:39:21 2004 and message logged at Tue Apr 27 23:39:21 2004
CC:70 KEY:0B ASC:48 ASCQ:00 initiator detected error message received

does this look like a disk error or a controller issue? perhaps bad cable or something?

thanks for any assistance

Tom

pasted below is the complete snip from my boot log about the SCSI devices
