The above message is from the DPT => driver's timeout handler, and it is complaining about a particular disk or => array you've got setup. => => The timeout for read and write operations from the DA driver is 60 seconds. => So that means that da0 didn't complete a read or write in 60 seconds. => => What sort of disk is da0? There are some disks that are known to lock up => under heavy I/O. It's been a long time since I looked at them, but probably they'll be "wrong" (any Quantum sort of is, and that's why I have them at home, not at work. :-) da1: <QUANTUM FIREBALL_TM2110S 300X> Fixed Direct Access SCSI-2 device da1: Tagged Queueing Enabled da1: 2013MB (4124224 512 byte sectors: 255H 63S/T 256C) Is there any way to test the individual disks-defects "through" the DPT controller?
