Who at IBM is driving this patch as well? Primarily: Martin Schwidefsky <schwidefsky.com> Secondary: Stefan Weinhuber <WEIN.com> Holger Smolinski <smolinski.com> The patch was developed on kernel version 2.6.26.2 stable Great, thanks Nigel. Please post a link to the upstream commit when that occurs. RHEL 5.3 is possibly a little aggressive for this patch. Any thoughts regarding pushing this out to a later release? I don't have tentative dates for 5.4 and 6 though. Are any available? Nigel, can you summarize what the impact is on not having this patch out? What functionality breaks for our 390 customers with a Symm? If it is more critical, it can have a more aggressive schedule. Also, it helps the process here a lot if you can get the IBM people to bless the patch for the mainstream kernel. Without this patch, we are not able to discover CKD devices on s390x platforms. For mainframe customers who have only have CKD devices, this means that they cannot manage their Symmetrix arrays with EMC's storage management products on RHEL systems. As the kernel for RHEL 5.3 is already frozen, we need to push this out. Is there any awareness of tentative releases dates for RHEL 5.4 and RHEL 6 ? Nigel, please contact Wayne or I directly - I can't post release dates in a public bugzilla. Updating version to RHEL 5.4 Updating PM score. Hans, Is this something you could handle, if-and-when we get a patch? Tom *** Bug 483154 has been marked as a duplicate of this bug. *** Nigel - please post a link to the upstream patch if you could... thanks! Moving across some updates from 483154 Refer to the 2.6.28 git upstream patch at: http://preview.tinyurl.com/awncad or http://git390.osdl.marist.edu/cgi-bin/gitweb.cgi?p=linux-2.6.git;a=commit;h=ab1d848fd6a9151b02c6cbf4bddce6e24707b094 Attaching RHEL 5.2 patch slightly modified from upstream patch (ckd device structure change) Created attachment 333738 [details]
RHEL 5.2 patch for EMC Symmetrix CKD ioctl
Patch built and tested on RHEL 5.2 kernel
Hans, any progress on testing this patch? Do you need help getting this done? Regards, Ric Ric, I can't test this because I don't have access to the required EMC hardware. Most likely someone from EMC has to test this. Regards, --Hans Hi Hans, I assume that Nigel who authored the patch can verify and test. Tom, were you looking for a reviewer? I can test if an installable version of the RHEL 5.4 kernel is available Hans - any updates here? Are you waiting for feedback from EMC? in kernel-2.6.18-152.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Please do NOT transition this bugzilla state to VERIFIED until our QE team has sent specific instructions indicating when to do so. However feel free to provide a comment indicating that this fix has been verified. Should there be 152 folder? I'm only seeing these 149.el5/ 19-May-2009 15:56 - 150.el5/ 21-May-2009 11:51 - 151.el5/ 28-May-2009 14:03 - Nigel - give it till the end of the day - doesn't look like Don has uploaded that version yet to his people page. Keep an eye on it! :-) Sorry, should be there now. Testing with 152.el5 looks good and I believe the fix is correct. Thank you. RHEL release information is still showing up as 5.3 though.
