Fixed In Version:		Doc Type:	Enhancement
Doc Text:	Feature: When iscsid is starting an offloaded iSCSI session, the operational state of the associated network interface is now checked. The network interface is brought into an administrative up state automatically if needed. Reason: Some iSCSI offload hardware requires the network interface to be up to function properly. Previously this required additional network configuration steps before starting iSCSI. Result (if any): Offloaded iSCSI sessions can be established without manually configuring the network interface first, iscsid will bring the interface up if needed.	Story Points:	---

Description Gris Ge 2012-02-28 09:00:40 UTC

Description of problem:

bnx2i iSCSI connection need its NICs in "up" state.
If bnx2x NICs is not configured as "on boot" while "iscsi" daemon is "on boot",
OS will hang at iSCSI loggin:

I have waited it for more than 20 minutes, still no timeout.

User need to bring OS into single mode and disable "iscsi" and "iscsid" service for "on boot".

Version-Release number of selected component (if applicable):
RHEl 5.8 GA

How reproducible:
100%

Steps to Reproduce:
1. Setup iscsi connection on bnx2i.
2. Make sure bnx2x NICs is not "up when boot" in /etc/sysconfig/network-scripts/
3. Make sure "iscsi" and "iscsid" daemon is on boot.
4. reboot OS.
  
Actual results:
OS hang at "iscsiadm -m node -l"

Expected results:
there are many options for bnx2i:
 1. Automatically enable NICs when got iscsi connection request.
 2. Make sure iscsi connection is isolated from NIC's state.
 3. iscsiadm timeout for bnx2i and warm user to bring NIC up.

Additional info:
"iscsi" and "iscsid" daemon is default on in run level 3 and 5, it will cause OS hang on boot and only single user-mode could disable it. I am requesting blocker for it.

Will try to replicate here when I get some time. Adding devel ack for 5.9. Probably a bad setting or daemon segfaulting so could not send response.

Comment 4 Bruno Goncalves 2012-10-17 14:28:33 UTC

I've just installed iscsi-initiator-utils-6.2.0.872-16.el5

the server has 2 bnx2i cards on eth2 and eth3.
eth2: bnx2i.00:10:18:88:e7:fc
eth3: bnx2i.00:10:18:88:e7:fe

after boot only eth3 is up. Then I ran:

iscsiadm -m discovery -t st -p na3170b.lab.bos.redhat.com -I bnx2i.00:10:18:88:e7:ff -I bnx2i.00:10:18:88:e7:fd

which means the server didn't bring up eth2 during login phase.

After bringing it up the login works

ifconfig eth2 up
iscsiadm -m node -l
