+++ This bug was initially created as a clone of Bug #805467 +++ Description of problem: When trying to boot via iSCSI and there is an Ethernet card eth0 and TOE card eth2 only eth0 is up, therefore the system boots using scsi_tcp instead of TOE interface. Dracut could bring NIC up based on the output of iscsiadm -m fw. Version-Release number of selected component (if applicable): dracut-004-273.el6.noarch Kernel: 2.6.32-251.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. Boot the OS via iSCSI 2. iscsiadm -m session -P3 the transport show: Iface Transport: tcp Actual results: Iface Transport: tcp Expected results: Iface Transport: bnxi (for example) Additional info: --- Additional comment from harald on 2012-03-21 07:56:15 EDT --- basically we have no "iscsiadm" in the initramfs. --- Additional comment from mchristi on 2012-03-21 14:55:44 EDT --- iscsiadm does not actually do what Bruno is asking for. iscsiadm/iscsistart just handles the networking for the iscsi interface. The cards Bruno is describing are have this weird quirk where they need the OS to do a ifup on the networking ethX device that the iscsi offload engines uses. Right now iscsiadm/iscsistart just prints out the ethx that needs the ifup. I think in rhel6.2 we worked around this by adding the networking info on the command line and forced dracut to setup up the networking on eth2 in Bruno's example. Harold, do you want iscsiadm/iscsistart to handle this? I am thinking this makes sense, because iscsiadm/iscsistart know about the quirks of the iscsi offload cards. It might get messy to do this in dracut. If so I will reassign this bz to me. --- Additional comment from mchristi on 2012-03-22 05:30:22 EDT --- Hey, I went and implemented this in iscsi-initiator-utils-6.2.0.872-37.el6. It is building in brew with some other stuff Bruno had me fix. --- Additional comment from pm-rhel on 2012-05-03 01:37:38 EDT --- Since RHEL 6.3 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux. --- Additional comment from mchristi on 2012-06-22 15:17:00 EDT --- This did not get completely implemented in 6.3. It got implemented for non-boot sessions only. So for 6.4 we need to modify iscsistart. Note that we must bring up the interface before iface_setup_from_boot_context, because we will want iscsi_sysfs_get_host_no_from_hwaddress to be able to match a MAC to a iscsi host. For some bnx2i cards, the card has to be ifupd for the iscsi interface to have a MAC. If it is not ifupd we have seen MACs with all zeros or no iscsi_hosts on different cards. --- Additional comment from mchristi on 2012-06-22 15:56:28 EDT --- (In reply to comment #6) > This did not get completely implemented in 6.3.

Created attachment 610125 [details] open-iscsi patch to ifup the corresponding L2 network interface Hello, I've created the enclosed patch, based on the upstream open-iscsi util, which addresses this issue as aforementioned by Mike Christie. The patch has already been acked by Mike Christie and has the following upstream commit reference: f0a8c95426d21413d9980d31740e193208e3280e Please incorporate this into the open-iscsi-util for RHEL6.4. Thanks. Eddie
