"rescan-scsi-bus.sh" did detect new LUN, but apparently not
removed ones.
However I need to test it on a system with a compatible bash shell

able to run the script without errors.
Did you try the rescan-scsi-bus.sh from sg3_utils v 1.37 or
earlier? The reason I ask is that a fair amount of work
was done on the rescan-scsi-bus.sh found in version 1.37
including syncing with Kurt Garloff's version 1.57 plus
patches from Hannes Reinecke and Sean Stewart.
Plus you need to call it with '-r', otherwise it won't remove any
stale LUNs. I'm sure it's documented somewhere ...
Hi Doug and Hannes,
I did indeed try but I was using an older version and without specifying
"-r" so it didn't remove anything.
I looked at the latest version's "remove" code (at around line 445 from
rescan-scsi-bus.sh) and it seems to delete disks using the scsi_device
sysfs "delete" function (which is the function I'm using right now).
I was unable to tell how the script detects whether a drive is gone or
has been replaced with another backend storage at the same LUN, which in
fact turns out to be the thing I'm more interested in (since I can now
delete stale luns).
Thanks in advance for your help!
Cheers,
Hannes
Regards,
Ben.
