Hi list,
I've got a question which might be slightly off-topic, but there's a Linux
aspect too.
I'm preparing a few dozens of registration harddisks for seismic field
equipment just now and would like to activate the SCSI settings which
provide automatic re-mapping of defective sectors "on the fly" so the
drive appears defect-free while the reserve sectors last.
There was a discussion on this list some months ago I remember, but there
seemed to be no summary.
Could some kind soul please list the mode page bits I have to set (and to
which values, of course) to achieve the goal described above - apparently
defect-free disks for a longer period (as the disks are used for about
6 months up to 1 year or even more without coming back to the lab for
re-low-formatting, and we're bound to readablility of every byte written) ?
I also know that there are tools to set/reset those features (scsi-config
or so), I'd like to receive pointers to a command-line driven tool though,
because I have to prepare about hundred disks (connect, boot, start X, start
X tool, stop X, shutdown, disconnect, redo from start - would take too much
time, so the shorter cycle connect, boot, start tool, shutdown, disconnect
is preferred :-).
Perhaps this should be a FAQ ? (I wasn't able to find the words "ARRE" and
"AWRE" in the current SCSI-HOWTO of 30Aug96, so I suppose it's not in there.)
TIA, Steffen
