Just after vSphere 6.5 was released I decided to upgrade my lab to 6.5. Most of the upgrade went pretty smooth, but two of my 3 distributed switches refused to upgrade. Googeling for a solution dit not help too much, probably since the product was released just a day before 🙂 When I tried to upgrade I got a message the vDS config could not be read. I also noticed I was not able to upgrade these switches to enhanced LACP.
I did find some kb articles regarding some wrong vCenter database entries for LACP in previous upgrades, so I had a feeling this was related to LACP (which I do not use) … Continue reading
When vSphere 6 was released, I decided to delete my RTM version of my external Platform service Controller and vCenter Server appliances, to replace them by the GA versions.
Installing the PSC went fine, but when installing the vCenter appliance, I was not able to register it to the PSC. I kept getting the message “Invalid credentials” every time I entered the SSO administrator password. Redeployed the PSC several time, using different passwords, but no luck registering the VCSA.
During an installation and configuration of an SRM solution for a customer based on EMC RecoverPoint 4.1 I ran in to an interesting issue.
When I tried to add the RecoverPoint Clusters on both sites using the RecoverPoint SRA 2.2 I received the following error message:
After reading the blog article by Erik Bussink on how to use the VSAN Observer software on a Windows vCenter Server, I quickly got annoyed by manually having to start the Ruby rvc script and the VSAN Observer every time
I created a little batch file that can be put on your desktop to launch the VSAN Observer
Just enter your credentials, vCenter server Name, Datacenter Name and Cluster Name and make sure the path to the rvc directory is correct, and of you go
After you started VSAN Observer, just connect to it via port 8010 on your vCenter Server, or add an exception for port 8010 in your Windows firewall to access VSAN Observer remotely, like described in Eriks’ blog
During the Horizon View 5.2 Beta I noticed the View Desktops Tech Preview. Since the Beta was covered by an NDA I was not allowed to publish this, but since the product is GA for a while now here’s the story.
The plugin will let you search for usernames in the vSphere Web Client search field and shows you the desktop(s) for this user. Continue reading
May 8th – 10th 2013 VMware will host a 3 day beta training at their Frimley UK HQ for their new VMware vCenter Operations Manager: Advanced Usage and Dashboard Design training.
This training course focuses on the advanced capabilities of VMware® vCenter™ Operations Manager™ 5.6, such as adapters, customization and management topics. You will learn how to use adapters, define custom super metrics, customize dashboards, and use the Custom user interface.
I have been fortunate enough to participate in an alpha training for this class and must say I enjoyed it very much. Very useful for people that want to customize their vCOps environment to show specific metrics or combined metrics
Cost for this training is around 50% of the normal price
See the attached info sheet, and if interested, register for this training here
Space is limited

While working on an upgrade to vSphere 5.0U1 on a Cisco UCS environment, where the ESX hosts boot from SAN, I noticed one of the hosts was not registered correctly on the EMC VNX, as it showed up as unmanaged. Because the ESX hosts boot from SAN, the host has to be registered before it can auto register, and when it was registered manually the host was not able to update the registration. Continue reading
Today I received a tweet from Chad Sakac, SVP Global SE at EMC, that he will be discussing some of the questions and concerns I raised in my blog post Challenges when upgrading environment with EMC CX4 to vSphere 5 and mixed CX4/VNX environment in next weeks Chad’s Choice WebEx, and in a blog post on his Virtual Geek blog.
Subjects for this call will be: Continue reading
Yesterday I wrote an article on issues when using a combination of CX4 and VNX in a vSphere 5 environment since ESX5 does not support on VAAI according to VMware and the VNX does. Simple solution would be to disable VAAI on all ESX5 hosts, but in that case your VNXes would also loose VAAI. Victor Forde pointed me to a blog post by Chris Wahl titeled “Forcing the NMP Plugin for Microsoft Clustering LUNs on vSphere” (good post by the way)
When reading this article, I realized you can not only use the array vendor and model strings to assign the VAAI filter driver to an array, but you might also be able to use the location (the combination of adapter, target, channel and LUN) for a device to assign the VAAI filter and VAAI Plugin to a specific array.
In short, you would need to remove the default VAAI filter and VAAI plugin rules for vendor=DGC and model=* and replace them by claim rules for based on the location where you would use the target identifier to filter on, for the array that would need to have VAAI enabled.
Unfortunately I don’t have a VNX in my lab (Someone at EMC that wants to trade my VNXe and a case of beer for a VNX? 😉 ) so I am not able to test if this would really do the trick. Continue reading
vCenter Operations Manager for View is a new VMware product that correlates al kinds of performance figures in a VMware View environment. More info on vCenter Operations Manager for View can be found here
vCenter Operations Manager for View basicaly is a set of front end tools for vCenter Operations Manager 5 that gets info from all View components.
Whenever you connect to the vCenter Operations Manager 5 UI VM, you automatically end up at the default login page for vCenter Operations Manager 5, which made me enter my credentials at the wrong place all the time, since this instance is only used for vCenter Operations Manager for View.
The correct way to access vCenter Operations Manager for View is go to the
https://<UI VM>/vcops-custom url, which off course can be bookmarked, but since I access this system from multiple desktops, I was looking for an easier way to do this, and succeeded.
It’s pretty simple, Continue reading
