I am trying to format a Jaz disk. From what I gather from the
manpages, the first step is to label the disk. The 'disklabel' manpage
says,
For a virgin disk that is not known to disktab(5), disktype can be spec-
ified as ``auto''. In this case, the driver is requested to produce a
virgin label for the disk. This might or might not be successful, de-
pending on whether the driver for the disk is able to get the required
data without reading anything from the disk at all. It will likely suc-
ceed for all SCSI disks, most IDE disks, and vnode devices. Writing a
label to the disk is the only supported operation, and the disk itself
must be provided as the canonical name, i.e. not as a full path name.
Since my Jaz drive is a SCSI device, I try the following command and
get the response below it,
# disklabel -r sd0s4 auto
disklabel: ioctl DIOCGDINFO: Invalid argument
But the following pops up on the console,
sd0(ahc0:4:0): UNIT ATTENTION asc:28,0
sd0(ahc0:4:0): Not ready to ready transition, medium may have changed
sd0(ahc0:4:0): ILLEGAL REQUEST asc:24,0 Invalid field in CDB
sd0 could not mode sense (4). Using fictitious geometry
What am I doing incorrectly? The manpage says it should 'likely'
succeed. Is this one of those other cases? Does anyone have a disktab
entry for a Jaz drive in that case?
Thanks for any help.
