OK, some new info:
1. with NO CD in the drive, I did not actually get the failure reported
before, but only the following messages:
cd0 at sym0 bus 0 target 2 lun 0
cd0: <IMS CDD2000/00 1.26> Removable CD-ROM SCSI-2 device
cd0: 3.300MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Logical unit not ready, cause not reportable
(and then subsequently cd0 was correctly attached and usable)
2. with a DEFECTIVE CD-R in the drive (that had been sitting in there
for some time I guess...) I reproduced the failure:
(cd0:sym0:0:2:0): autosense is NOT valid
(cd0:sym0:0:2:0): flags = 0x40 status = 0x4c
(cd0:sym0:0:2:0): got CAM status 0x4c
(cd0:sym0:0:2:0): fatal error, failed to attach to device
(cd0:sym0:0:2:0): lost device
(cd0:sym0:0:2:0): removing device entry
and then retrying the command with camcontrol yields /valid/
sense data.
Thomas.
