Sometimes, I need to resize the device on the target.
Technically, I do this as follows:
lvextend -L+5G /dev/san14/blah1
tgt-admin --update tid=20 -v -f
However, the initiators won't see the change unless we "rescan" the
device, i.e.:
echo 1 > /sys/block/sdah/device/rescan
This is a boring thing to do when we have more initiators connected to
that target.
Also, the initiators will likely have a different device used for that
target (/sys/block/<DEVICE>/device/rescan), making the thing even more
boring.
Is it possible to send a reset/rescan to all initiators connected to a
given target, which would trigger the initiator to rescan the device
(and its size)?
