I have installed vSphere 6 on my servers. The Lenovo storage is providing 2 iSCSI targets to fulfil the requirement of 2 shared datastores for HA. Both datastores are part of an SDRS cluster. Besides this I have created a cluster which has HA and DRS enabled. On the network side I have created 3 standard vSwitches each with 2 Gbit network adapters. vSwitch0 is for the virtual machine traffic. vSwitch1 is for iSCSI and vSwitch2 is for VMotion. Yes I know thats a bit the old school way of networking but hey thats only my Homelab so a dvSwitch with Network IO control should not be required. A simple setup is sufficient for Homelab use. Maybe in the future I’m going to change it but that will have to wait until the next vSphere release.

So whats next?

Next will be to setup vRealize Operations Manager 6.3 to improve my troubleshooting knowledge of this product. Additionally I have an idea about how to simplify the troubleshooting and improve the supportability of the product. But this is a different topic. Today I’m going to install the lastest ESXi patches and check for upgrades of my vCenter appliance.

VMware ESXi HA agent failed

If you force problems with reconfigure HA on a ESXi server in a HA Cluster. A possible solution to resolve this is to uninstall the vpxa and the ha-agent. This can be done using the unsupported mode.

Steps:

* set ESXi in Maintenance Mode
* disconnnect ESXi from Virtual Center
* remove ESXi from Virtual Center
* connect with SSH to ESXi or direct using something like HP iLo
* execute the following commands

cd /opt/vmware/uninstallers/
./VMware-aam-ha-uninstall.sh
./VMware-vpxa-uninstall.sh

* add ESXi to Virtual Center
* exit ESXi from Maintenance Mode

* repeat this with all Nodes in the cluster
