If you reread my message, I hope you will find a bit of clue:
echo y > /sys/block/sdm/device/delete
(or something like that anyway.)
That's needed for exactly this purpose: to remove a device which is
marked 'offline' in the kernel somewhere - to be able to re-add it
later - either with this script or just doing that magic add-single-device
command manually.
I should have listened sooner; I wasn't able to follow the paths in the
re-add command, so I didn't do the delete.
I did the delete (the above syntax is correct) -- ran the rescan script, it
added it back - and the device is accessable again.
Thank you Michael & Forrest.
