OK - but at present, I can remove a quiescent drive
and /proc/scsi/scsi still serves up the cached info
about the drive. It seems there are at least a
couple of dots left that I could/should join.
Since they appear as scsi devices, I sort of expected
to be able to implement "scsi add-single-device n" and
"scsi remove-single-device n", but for all I know this
may be out of fashion or otherwise useless these days.
I can see how I may require HBA-driver-level
hooks to respond to phys going on/off-line, or
some such mechanism.
