Hello all,
answering to my own posting ;-) I updated the system to Debian 8, which
in turn allowed me to build the most recent git commit (1dfb88a4df) of
open-iscsi. With the version from git, open-iscsi (non-flash) logins
as well as offload engine (flash) logins are registered on the target
side (Dell EqualLogic) as jumbo frames enabled sessions. So, no need
for qaucli anymore!
The issue with incoming CHAP-authentification on offload engine (flash)
logins, which i described below, is still persisting though. I also
tried enabling the bidirectional CHAP option in the HBA firmware through
the Dell System Setup, but this didn't change the behaviour described
below.
Thanks & best regards,
Frank Fegert
