Is there an official stance on upgrading to/using ESXi 5.5U2 as install media? I see that U1 is specified explicitly on the supported Hypervisor list, is there a target date for U2 certification?

I just did upgrade NX1350 to VMware ESXi 5.5 Patch ESXi550-Update02 Build-2068190 using command line options and have no issues but have to take a note Nutanix Engineers dlink7 & PaulR have mentioned in Previous topic: fdm and pynfs regarding the uninstall/re- install pynfs.

Usally major patches are 60-90 days

Minor go right ahead.

Hi dlink7,

Any document is released now about ESXi 5.5U2? Since customer is purchased NX-3360 64GB DOM, is that mean it do not have fdm and pynfs issue(s)?

Additionally, all of the nutanix node now is in ESX 5.5.0 version, if I upgrade to ESXi5.5U2 and the 10Gb driver can be ignored, right?

We support 5.5 U2 now officially.

If you have 64GB DOM's, you are correct, those issues are gone.

RE 10Gb driver: I am not sure what you mean specifically, but if you upgrade to 5.5 U2, make sure you upgrade to NCC 1.3 ( or current GA version), and run "ncc health_checks run_all", that will validate your installed drivers and make sure you are at the right level.

A small update on Jon's note.

ESX 5.5 U2a is availble on VMware website for download. For some reason VMware has removed ESX 5.5 U2 image from their website.

Hi Jon,

I had the problem with vDS migration from Standard switch especially with VMK (management) interface. I am using the same ESXi5.5U2 (2068190) version. The host lost the connection, when I took direct console of the host, found the below:

vmhost001 Failed: Failed to get enabled state for module cbrc_filter. (Error interacting with configuration file /etc/vmware/esx.conf: Timedout while waiting for lock. /etc/vmware/esx.conf.LOCK. to be released. Another Process has kept this file locked for 20 seconds. The process currently holding the lock is hosted-worker(34271). This is likely temporary condition. Please try your operation again.)

Then, I entered root and password to login the console. Then ran the following commands to bring back the connection:

esxcfg-vmknic -l
Found that "Managment Network" "Enabled" set to false (technically it was disabled)

it is not allowing to enable, again, I ran the command ps -t | grep "dcui" to find the process id for dcui, then

#kill 35112

esxcfg-vmknic -e "Management Network" , then host started to ping and vcenter connected.

Any idea why this happening and any fix or patch?
