Determining the LUN ID for a specific LUN in your VMware Infrastructure used to be simple. It was listed as one of the properties of the datastore you selected in the VI Client. Nowadays, more often than not, I dont see the LUN ID in the vSphere Client. Instead, I see [...]
I have promised you I would post this script, so here it is!
This Powershell script generates an overview of any items that are not available to every ESX server in a VMware cluster. These items might prevent your vm’s being vmotioned by DRS or restarted by HA. Pretty serious [...]
I showed you before how to compare the datastores for two ESX Servers using the VI Toolkit. But ideally, one would like to compare all ESX servers in a cluster to ensure VMotion and HA compatibility.
So I started scripting and it turns out to be pretty simple: only 4 lines [...]
I’ve created another way to gather and display VMware Virtual Disk information with the Powershell VI Toolkit.
The attached script generates a csv-file with all Virtual Machines’ Disks, in which Datastore they are stored, the LUN IDs of the extents that make up this Datastore (in HEX) and the [...]
One of the challenges in managing a large VMware Infrastructure is keeping all ESX Servers within a cluster equal. This is essential for having vmotion capabilities and therefore essential for a solid HA configuration. I have showed you earlier how to add the LUN Count for each ESX Server to your VI [...]
Using VMware seriously requires a lot of (shared) storage. This kind of storage (on a SAN for instance) is quite expensive. So you might want to check if you are wasting a lot of this space. When you look at the storage in VMware, it consists of multiple abstraction layers. A [...]
Today’s helpful scripts are ready to use scripts that generate an overview of your VM’s and your Datastores and save it to a HTML file. Great for reporting purposes. Easy to modify to meet your needs. Give them a try:
Get-DatastoreSizes (Rename to .ps1)
This one shows datastores with Used [...]
Today’s oneliner is an incredibly fast way to check the usage of your VMware datastores. You should first connect to Virtual Center in the following way:
$VC = Connect-VIServer “YourVCServerName”
Here comes the oneliner:
Get-Datastore | Sort-Object Name | %{Get-View $_.Id} | Format-Table @{Label=”Name”;Expression={$_.info.name}}, @{Label=”NumVMs”;Expression={$_.vm.length}}
Only interested in datastores that are not used? [...]
Do your vm’s have multiple virtual disks? Do you use different datastores for your vmdk’s? Are you ever wondering where the disk files of each of your vm’s is stored? Yes? Well, I’ve got something to help you out.
Today’s handy script of the day creates an overview of the locations of all your vmdk [...]
