I am currently working on a script to do a vmfs unmap across a wide number of datastores. I have a script for doing it against a single datastore, and it works well, but in this case I have hundreds to touch, so this is my thought process:
- Loop through every cluster in the datacenter and grab the first vmhost returned.
- Perform a Get-Datastore on that host to pull all the datastore names
- Connect to that vmhost and loop through all the datastores to perform the unmap cleanup
Attached is my script thus far:
$aHosts = @()
$report = @()
$aClusters = Get-Datacenter "MyDC" |
Get-Cluster |
Select Name
foreach($sCluster in $aClusters) {
$sHost = Get-VMHost -Location $sCluster.Name |
Select -First 1 |
Select Name
$aHosts += $sHost
}
foreach ($sHost in $aHosts | Sort Name) {
$sStore = Get-VMHost $sHost.Name |
Get-Datastore |
Select Name
$report += $sStore.Name
}
$report | Out-GridView
First and foremost, as I am still learning with PowerCLI, while this works I wonder if there is not a simpler way to accomplish this through a better pipeline call than splitting it out into two for loops. I attempted to do so but unsuccessfully. Secondly, the output I get has just the datastore name. I have tried a couple different ways of getting the hostname and the datastore name with each pass, but it doesn't come out the way I would expect. My end goal, as I stated, would be to have for each VMHost a list of its datastores, so I can cycle through them. Any suggestions would be welcome.
