I think you are asking two questions here:
1). Should we connect to all portals listed in the iBFT irregardless if some
of the flag.
2). Should we connect to the portals on both ports.
The second is much easier to answer - that depends on the iBFT structure. There
is a linkage
between the target portal and the NIC entry (each target portal can only
specify _one_ NIC
however). If that is not set, we would not connect. However if the
iBFT specifies two NIC entries and four targets, where one is associated with
the first
NIC, while the three other are with the second NIC, we ought to:
a). During bootup login to only the boot-up portal
b). Later on we can connect to the other target portals. But I think we
haven't even
done that as the purpose of iBFT is to be the 'iSCSI _Boot_ Format
Table' - so we only
use it during bootup.
In regards to the first 1) question the spec does not specify (this is from my
memory so
I might be wrong here) whether you need to log-in or not. If you are interested
in doing
some of this work to have it working properly contact me off-line and we can
work together
on improving the iscsiadm ibft sysfs handling (or rather the lack of it right
now and add
the correct sysfs handling) and adding this in.
