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 I tried to upgrade my lab environment from vCenter 6.0 with external PSC to vCenter 5.5, I ran in to an annoying issue. I tried to upgrade my PSC, but the installer was not able to determine the version from my current PSC. It assumed it was 5.5 and I had to confirm this, which of course, I did not. No way to tell it it was really 6.0 …
The second keynote is usually a more tech savvy, and packed with demos (which used to be live but are replaced by recorded demos nowadays).
Keynote starts with Sanjay Poonen,General Manager of End-User Computing.
Sanjay starts talking about the transformation of education, healthcare, and low tech branches like tea estates, digitally transforming the end user. Continue reading
I was fortunate enough to attend VMworld again this year. This is my take on the Monday morning Keynote.
Pat Gelsinger, VMware’s CEO kicks of limping a little due to a broken foot.
21 Alumni Elite present, whom have attended all VMworlds (all US VMworlds to be more specific) They will all get lifetime access to VMworld for themselves and their spouses.
Let’s see if VMworld Europe Alumni Elite will get the same privileges … 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.
Recently I got a call from a customer he was not able to log in to his ESX 5.5 hosts anymore trough ssh, and could not vMotion VM’s anymore. It seemed like the ssh daemon died and trying to start it again did not work.
I was able to log on to one of the hosts (DL380 G8) and have a look at the vmkernel.log file.
In the log file I saw a line that read:
WARNING: Heap: 3058: Heap_Align(globalCartel-1, 136/136 bytes, 8 align) failed. caller: 0x41802a2ca2fd
Google brought me to VMware KB article 2085618 with the title “ESXi host cannot initiate vMotion or enable services and reports the error: Heap globalCartel-1 already at its maximum size.Cannot expand” which sounded exactly like our problem, and seems to be caused by a memory leak in the hp-ams service.
And that’s where the fun started ….
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
IMPORTANT UPDATE AT THE END OF THE ARTICLE
In my lab I use to test and play with numerous VMware solutions, I have several nested ESXi servers running. Nested ESXi servers are ESXi servers running as a VM. This is a not supported option, but it does help me to test and play around with software without having to rebuild my physical lab environment all the time.
So first a little on the setup of my nested ESXi servers
The VM’s for my nested ESXI servers have 4 NIC’s
The first NIC connects to “vESXi Trunk” This is a port group on my physical ESXi hosts that is configured on a vDS with VLAN type “VLAN Trunking” so I get all VLAN’s in my nested ESXi host:
I use this VLAN trunk to present my management network and my VM networks to my nested ESXi servers
I also have a NIC that connects to my vMotion network, and two nice that connect to my iSCSI networks. I use two subnets and two VLAN’s for my iSCSI connections.
In my physical setup I use jumbo frames in these networks, and I did the same in my nested ESXi hosts, and it worked perfectly … Until I upgraded my nested ESXi hosts to vSphere 5.5 … Continue reading
The VMWorld schedule builder for Barcelona is live, please attend our session at:
