vSphere ESX: Replace / Update the VMware Tools ISO

vSphere: Cannot Change the Host Configuration

KB ID 0001565 Problem There’s always one! I had a single ESX host that refused to add a datastore? Failed to create VFMS Datastore {Name} – Cannot change the host configuration.

KB ID 0001534 Problem I was building some new ESX 6.7 U1 (HPE) servers this week, they had Emulex Fiber HBA’s in them. When it came to ‘allowing’ them access to the SAN, I went to get the Port World Wide Name; And was presented with this; Not only is that 19 Characters long, and not 16 characters, but BOTH VMHBA’s WERE THE SAME! Like MAC addresses they should be unique? So I’m guessing this is a bug....

Disable ATS Heartbeat

KB ID 0001529 Problem After ESX 5.5 Update 2, VMware added ATS Heartbeat.Some vendors, (like HPE SureStore and VSA) recommend that this is disabled. I can’t find any info about whether it’s safe to do this in production, so to be on the safe side I placed the hosts in maintenance mode first. Enter Maintenance Mode Use the following command; vim-cmd /hostsvc/maintenance_mode_enter Disable ATS Heartbeat Use the following...
