VMware: Fiber Channel HBA Reports Wrong WWN?
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...
Virtual SAN: Suppress ‘Datastore Usage on Disk’ Alarm
KB ID 0001527 Problem While deploying a HPE StoreVirtual VSA this week. We noticed all the local Datastore were showing an ‘Alarm’. If you are unfamiliar with Virtual SANs, then you give all the LOCAL Storage to them, which then gets ‘aggregated’ and provided back to the host(s) as fault tolerant clustered storage, like so; Which is great, but the VMware hosts just see that their LOCAL Datastore(s) are full,...

VMware Fusion on macOS Mojave: No Mouse or Keyboard
KB ID 0001523 Problem While building my new MacBook, I installed VMWare Fusion, (I always run a Windows VM, in case I have to do something on Windows). But no matter what version I tried to install, I could not interface with the VMs, (no mouse or keyboard). I ran Fusion 11 on my old MacBook, (running Mojave). So I was a bit confused.

Manually Extracting VMware Tools Drivers
KB ID 0001518 Problem If you want to get hold of the actual drivers from VMware tools, e.g. to have them in a machine that you will be deploying into VMware ESX/Workstation etc, then this is how to do it. Solution I’m using WinSCP to connect to one of my ESXi servers, (it’s free, and just works!) From the root directory locate vminages and open that. Tools-isoimages, (this might seem long-winded, but if you keep an eye on...
