For those looking for the default PIN for the bluetooth connection of a HP OfficeJet H470, it's 0 0 0 0.

Although it can be found in the manual somewhere, it's easily overlooked.

Sometimes, you need to temporarily start a service (such as SSH) to perform some maintenance task. PowerCLI can help you with this:

To start the SSH server on each host of a vCenter:

Get-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Start-VMHostService

To stop the SSH server:

Get-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Stop-VMHostService -Confirm:$false

As always, you can make adjustments to the oneliner to select another service to start/stop, or further limit the selection of hosts to a cluster or a group of hosts (e.g. filtered by name).

If you're making changes to the datastore, setting up a new cluster and have a lot of hosts, and wish to set up system logging, you can do so very quickly using PowerCLI.

First, add all the hosts to the vCenter like you normally would. Then, connect to the vCenter server and run this cmdlet:

Get-VMHost | % { $vm = $_ $vm | Get-AdvancedSetting "Syslog.global.logDirUnique" | Set-AdvancedSetting -Value "True" -Confirm:$false $vm | Get-AdvancedSetting "Syslog.global.logDir" | Set-AdvancedSetting -Value "[DataStore01] ESXiLogs" -Confirm:$false}

The cmdlet above will set the system log location to a folder on DataStore01 and enables unique log di  ...

When performing large storage migrations, it may be useful to get a list of VMs and the datastore and/or folder they are located in. PowerCLI can provide this very quickly:

Get-VM | Select Name,@{N="Datastore";E={[string]::Join(',',(Get-Datastore -Id $_.DatastoreIdList | Select -ExpandProperty Name))}},@{N="Folder";E={$_.Folder.Name}}

You can further pipe this to other cmdlets (such as Where-Object to filter even more), or export it to a CSV.

You can also go into more detail and determine the location of each virtual disk (VMDK) of each VM:

Get-VM | Get-View | % { $name = $_.Name $_.Layout.Disk | % { New-Object PSObject -Property @{ Nam  ...
