If that datastore is known on all the ESXi nodes, it should be possible to vMotion a VM between those ESXi nodes.
If you have the list of ESXi nodes and the name of the datastore, you could do something like this
$tgtVMHost = 'esx1','esx2','esx3'
$dsName = 'DS1'
Get-VMHost -Name $tgtVMHost -PipelineVariable esx |
ForEach-Object -Process {
New-Object -TypeName PSObject -Property ([ordered]@{
Datastore = $dsName
VMHost = $esx.Name
Status = if(Get-Datastore -Name $dsName -RelatedObject $_){'ok'}else{'nok'}
})
}
