March

This might not be a new one to a lot of folk, but it certainly was to me! This week I was proactively updating some NIC driver and firmware for a customer to avoid a known issue where the FCoE driver could cause an ESXi Purple Screen of Death (PSOD). Both firmware and drivers needed to be upgraded to maintain interoperability. While I am very much looking forward to vSphere Lifecycle Manager (finally!

This approached very quickly, and next week one of the hottest VMware events in ANZ will be held in Sydney and Melbourne - the VMUG UserCon events! VMUG UserCons are a free one day event held once a year featuring a small vendor expo area, lots of educational sessions throughout the day, excellent opening and closing keynotes and of course the opportunity to mingle with industry peers, catch up with old friends and make a few new friends.

Well, it’s that time of the year again. The VMware User Group (VMUG) UserCon’s are on again this week in Sydney (Tuesday 20th March) and Melbourne (Thursday 22nd March), Australia. VMUG UserCon is a free day long event filled with a few keynotes, breakout sessions, networking and checking out the exhibit hall. I’ve personally only attended one UserCon, which I wrote about here, but I was really impressed at the organisation and presence from VMware, sponsors and community members.

On Friday the 9th of March (morning of Saturday the 10th in Australia), VMware announced the results of the vExpert 2018 award, which is given to those who have performed various VMware advocacy related activities in the 2017 calendar year. I’m happy to say that VMware has deemed me worthy to be a vExpert again, which will mean this is my second year in the program. It’s a great program to be a part of with several perks, one of the most valuable (yet sometimes time consuming!

Quick post. The other day I saw an alert on an ESXi 6.0 host as follows: Agent can’t send heartbeats: No buffer space available The host was responsive and connected to vCenter Server, and the VMs were running OK on the host. I checked the vmkernel / hostd / vpxa logs, and the only mention of this was a one liner in the vmkernel log which repeated the error message above.

[toc] Introduction If you work in the VMware suite of products and haven’t heard of or checked out the VMware Flings website, head on over and check it out! As the website says; “Flings are apps and tools built by our engineers that are intended to be played with and explored.” A lot of products and features that make it into the product start out as being VMware flings. Some recent ones that come to mind are the vCenter Migration Tool (migrate Windows vCenter to the Appliance), HTML5 Web Client, ESXi Embedded Host client … you get the drift.

In my lab, I deployed vCenter using the appliance as an embedded node using vCenter 6.0.0b. I purposely deployed this build, as an embedded deployment for two reasons: I haven’t used the appliance before, and I wanted the lab to be simple, but I also wanted to see the upgrade process in action on the appliance I wanted to deploy an external PSC and follow the process to re point the original VC server to the new external PSC, as outlined here: http://pubs.

I’m working on rolling out vCenter Host Profiles at work, to keep an eye on our configuration and also to assist in the deployment of new ESXi servers into our environment. If you haven’t checked out host profiles and you have a VMWare Enterprise Plus license, it is a must! I’m working through a few of our clusters that are connected to our Nimble Storage arrays using the iSCSI Software Initiator, and that use the Nimble Path Selection Policy (PSP) to determine the best path policies from the ESXi host to the storage.

I’m still getting my lab configured and I am planning on using Windows Server 2012 R2 as an iSCSI target (as well as an NFS server). The server in my environment is called Storage01. I’ve added 2 NICs to the machine, and was trying to figure out where to set the network binding for the iSCSI traffic. It wasn’t where I expected, and I couldn’t find much online, so I thought I’d write a quick note on it.
