Description
IBM Bug Proxy

Exactly how is this implemented in the driver? What needs frobbed where to enable this on a running system? Hello Red Hat, to find out details about the implementation, I guess the best source will be the source code (the Layer2 functionality for HiperSockets is already upstream). To enable Layer2 on HiperSockets, having the device offline, you have to: echo <integer> > /sys/devices/qeth/<first_subchannel>/layer2 More info can be found under (recently updated): http://www.ibm.com/developerworks/linux/linux390/development_documentation.html Device Drivers, Features, and Commands - SC33-8411-01 Chapter 7 Info provided... We need IBM to provide the following: 1. Workflow inside anaconda that is impacted. 2a. Patches for anaconda to provide options or UI wire screens. 2b. Kickstart options to support the above. ------- Comment From gmuelas.com 2009-10-21 10:41 EDT------- (In reply to comment #8) > We need IBM to provide the following: > > 1.

IBM is requiring Red Hat to enhance your RHEL intaller because IBM does not have the patches, sorry. > 2b. Kickstart options to support the above. Please check with David Cantrell and Brock Organ, but I think it could be "LAYER2" Thank you for your support, Gonzalo Muelas Serrano. Fixing this bug requires patching linuxrc.s390 to ask if you want layer 2 or layer 3 if you choose the HiperSockets driver, then optionally prompting for a MAC address if you pick layer 2. If the user picks layer 2, the script needs to echo 1 to /sys/devices/qeth/<subchannel>/layer2 The network.py file may need patching to handle the layer 2 vs. layer 3 difference to ensure the MAC address is treated as optional when in layer 2 mode. This bug may need to be cloned for NetworkManager to address the UI configuration elements in nm-connection-editor and possibly nm-system-settings. IBM is signed up to test and provide feedback. I'm hesitant to add a QA ack for this item until we have a testable reference implementation in fedora first ... can we start to identify, build and test the changes there? (Then when that process is complete we can address the RHEL functionality with confidence that our specification will match the feature need ...) ------- Comment From mgrf.com 2010-01-25 04:29 EDT------- (In reply to comment #12) > I'm hesitant to add a QA ack for this item until we have a testable reference > implementation in fedora first ... can we start to identify, build and test the > changes there? > (Then when that process is complete we can address the RHEL functionality > with confidence that our specification will match the feature need ...) At this point in time, RHEL 6 on System z is the best "Fedora" on System z we've got.... and RHEL 6 anaconda is being rebased from F13... Without a working Fedora implementation we are unable to approve this for RHEL 6.0 inclusion. Closing as DEFERRED, resetting flags and moving to the RHEL 6.1 tracker for review for inclusion in that release. ------- Comment From mgrf.com 2010-02-11 07:28 EDT------- This feature is implemented in linuxrc.s390 by System z. It has been discussed upstream last year and is upstream with Fedora12. Feature tests passed once on alpha build RHEL6.0-20091130.0 Final feature tests planned on RHEL6 betas Additional changes in e.g. nm-system-settings from Network Manager should not be required The git commit: layer2 option provided for all qeth device types: http://git.fedorahosted.org/git/anaconda.git?p=anaconda.git;a=commit;h=9249e40f42ffbbdcf42cd1caad72e3d622c7a75b Based on comment 12, moving to MODIFIED since this feature has been present since anaconda-12.38.5-1. ------- Comment From mgrf.com 2010-06-15 01:42 EDT------- This feature is verified on R6 snapshots Set feature to "verified" Thx Setting VERIFIED flag based on latest feedback. Moving to VERIFIED based on comment 15. Thank you for testing. Red Hat Enterprise Linux Beta 2 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. |
