Dell R740 issues with XenServer 7.1/7.2 (Continued)

My previous post (https://allthingstechsmb.blogspot.com/2017/11/dell-r740-issues-with-xenserver-7172.html) indicated I was setting up 2 new R740s for our upgraded CAD/Revit VDI deployment.  We've had a few issues/learning experiences.  This is an extension of that posts with things I've found out since and new issues that have come up.  In addition, XenServer 7.3 solved one of our issues.

Storage Controller - H740p

This is a continuation of the issue with the H740p driver from the previous post.  This issue was resolved in XenServer 7.3, with the supported driver being included in the 7.3 install media.

Crash Dumps when booting in UEFI mode

While they have worked perfectly, I have been seeing crash dumps reported in XenCenter on every reboot when XenServer is installed in UEFI mode.  If you boot with BIOS and install, there are no Crash Dumps.

Per Rody Kossen (@R_Kossen), This will be fixed in XenServer 7.4, which is unofficially set to be released later this month (mid February 2018).

Per Bob Ball (@_BobBall_):


Network Information Disappearing

We've had issues with this for awhile, where the networking information disappears on the console of XenServer when added to a pool as secondary and then rebooted.  This shows over iDrac and on physical console access, but not in the console view on XenCenter.



Tobias has had some success by updating firmware, but we have not seen that same result:

Here's another discussion about this issue:

Its interesting that this issue didn't show up initially after the 7.3 upgrade, but the network status went away again when changing timezone.

On that note, another post coming soon with time/timezone issues in 7.3 and a fix!

  1. The megaraid-sas driver available at https://support.citrix.com/article/CTX230552 seems to work fine for xenserver7.2.
