Consequence: iSCSI discovery via a TOE (TCP Offload Engine) interface fails when the iscsiadm -m iface has never been executed.
Cause: This is due to the iscsiadm -m discovery command not checking interface settings while the iscsiadm -m iface does.
Fix: iscsiadm will try to create the default ifaces when it cannot fine one passed in.
Result: Users do not have to run the extra iscsiadm -m iface command before running a command that operates on a iface.

Cause
"iscsiadm -m discovery" doesn't check iface settings. But "iscsiadm -m iface" does.
Consequence
iscsi discovery via TOE iface will failed if "iscsiadm -m iface" has never been executed.
Workaround
run "iscsiadm -m iface" at least once after iscsi-initiator-uitls installed. Once iface setting been updated, future discovery could perform without any error.
Result
This bug only affected user who use hard-coded TOE iface for discovery. Normally, user needs to use "iscsiadm -m iface" to check the interface name, then discovery. Hence normal user will not affected.
This bug only happen if "iscsiadm -m iface" has never been executed.

Install iscsi-initiator-utils on server with iSCSI TOE card. 2. Perform disovery like this: iscsiadm -m discovery -t st -p \ na3170b.lab.bos.redhat.com -I "be2iscsi.00:00:c9:a0:e9:0b" 3. discovery will failed if "iscsiadm -m iface" not execute before. Actual results: discovery failed with "iface not found" error Expected results: discovery correctly finished. Additional info: "iscsiadm -m iface" will check and setup correct iface. this should also be execute before discovery.
