Hi,
I want to report (ugh, finaly) succesfull use of CAM on a box with AHA
2940U2W and Seagate Barracuda Ultra2 disks. See the dmesg dump for
details bellow.
I have one question concerning the information shown by the disklabel
command.
ferda:/root# disklabel -r da2
# /dev/rda2c:
type: SCSI
disk: da2s1
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 255
sectors/cylinder: 16065
cylinders: 1106
sectors/unit: 17783240
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 17783240 0 unused 0 0 # (Cyl. 0 -
1106*)
e: 17783240 0 4.2BSD 0 0 0 # (Cyl. 0 -
1106*)
Some values like rpm shown by disklabel do not match the factory values.
For example the rpm here is 3600 and the disk documantation says 7200.
Number of cylinders is 1106 vs 7520. I'm not experienced enough to see
whether these inconsistencies are something I should be worry about or
not.
Thanks
Mira
