Hello all,
another day, another issue ;-)
In the meantime i moved on trying to get access to the storage LUNs
without jumbo frames, but with CHAP-authentification in the iSCSI off-
load engine of the HBA enabled. It seems - see output below - i can
set the outgoing username and password just fine by either directly
setting the parameters:
flashnode.session.username
flashnode.session.password
or by indirectly referencing a CHAP table entry via the parameter:
flashnode.session.chap_out_idx
Both ways for incoming CHAP-authentification via the parameters:
flashnode.session.chap_in_idx
flashnode.session.username_in
flashnode.session.password_in
do not seem to work properly - see error messages below. This was
tested with Debian 8 and Open-iSCSI build from the latest git commit
(1dfb88a4df).
According to the "-h" output there seems to be no debug flag to the
"host" command. So just to verify, before i dig into the sources, are
the "flashnode.session.(username|password)_in" parameters supposed to
work at all and if yes are they analogous to the "node.session.auth.
(username|password)_in" parameters?
Thanks again & best regards,
Frank Fegert
