Thanks! I didn't realise it is both a target and an initiator. Apart from a few tests years ago, I don't remember using the in-kernel iSCSI target (which was flaky for me at the time - the initiators who were using it didn't reattach after a reboot). As far as the initiator, I've only tried it once to find out how it works, so I have zero experience with it.
