[sles-beta] [Sleha-beta] ISCSI issues with SLES12B7 - part2 ( ISCSI 'initiator' driver)

[Darren Thompson]

Richard

That leaves a couple of posibilites:
1. I have just got all my configurations wrong at both ends (sadly, highly
possible)
2. The SLES12 initiator is no longer compatible with the SLES11 target (bad)
3. There is a bug that i have discovered somewhere which you are not seeing.

I will do some more testing to see which of these is the most likely cause.

Can you send through screenshots of the "correct configuration" so i have
something to compare against :-) please.
