OK...decided to do a fresh install of Fedora (FC12)...install completed to
iScsi target...now trying to boot it.
Fedora is finding the target, then then throwing an "I/O error". When I snoop
on the ZFS server I see the following:
1) Initiator connects and logs into the target OK
2) Initiator issues a iScsi opcode 0x25 (Read Capacity)
3) Target responds with a 'Illegal Request' response (see below).
Based on my read of the Iscsi RFC on a *target* is supposed to use opcode 0x25
and here we have the Fedora initiator doing it so it seems like the Solaris
target is responding properly and the Fedora initiator seems broken...anyone
understand this?
