I had the need to enable SSH on all my hosts to make configuration changes. Instead of manually going to each host and enabling the service I searched for a powercli command. I was able to find the following little snipit – and it did exactly what I wanted
Get-VMHost | Get-VMHostService | Where { $_.Key -eq “TSM-SSH”} | Start-VMHostService
This rolled through each host in the cluster and turned on the service.
When I was done I changed start to stop and turned off SSH across all the hosts.
How often are you looking to see if all your ESX hosts are at the same revision level? Did one get left behind, or did someone run odd updates against one and you are trying to figure out the out one out?
This is very easy to find via PowerCLI. Once you are authenticated to one or many vcenter instances (connect-viserver) you can run one of the following commands – it really depends how much data you want to capture.
get–view –ViewType HostSystem -Property Name,Config.Product | select Name,{$_.Config.Product.FullName}
This will give you output similar to:
Name $_.Config.Product.FullName

mnepesx22-p.corporate.ltcg.com VMware ESXi 6.0.0 build-3825889
or
get–view –ViewType HostSystem -Property Name,Config.Product | foreach {$_.Name, $_.Config.Product}
This will give you output similar to:

Both could be tagged with a >filename at the end if you wish to save to a file versus output to the console screen.
