<source lang="powershell"> Get-VM MyVM | Get-Snapshot | Select-Object -Property Name, Description, Created, SizeMB | Format-List * </source> | |||
==== Start Snapshot on Multiple VMs ==== | |||
Assumes you've already got an array object of VMs containing the VM's you want to snapshot (eg <code>$VMs = Get-VM -Location (Get-Folder -Name "MyFolder")</code> for VM's in a particular folder, see [[#Get_list_of_VM.27s|Get_list_of_VM's]] for further info) | |||
<source lang="powershell">New-Snapshot -Name "Pre change XYZ snapshot" -Description "Requested by TJ Hooker" -Memory -Quiesce -VM $vms </source> | |||
==== Roll-back to Snapshot on Multiple VMs ==== | |||
Rolls back VM's to snapshots previously taken (assumes you've already got an array object of VMs containing the VM's you want to rollback for) | |||
<source lang="powershell">foreach ($vm in $vms) {Set-VM -VM $vm -Snapshot (Get-Snapshot -VM $vm -Name "Pre change XYZ snapshot") -Confirm:$false}</source> | |||
=== | ==== Delete/Merge Snapshot on Multiple VMs ==== | ||
Deletes snapshots previously taken so that VMs continue as they are currently, but lose the ability to fall-back to the snapshot (assumes you've already got an array object of VMs containing the VM's you want to delete snapshots for) | |||

Set all SCSI disks to use round robin multipathing | |||

The above came from Troy Clavell's post to be found at http://communities.vmware.com/thread/339480 | |||
Note that you should also set the IOPS per path to 1 (default is 1000), there is some debate as to whether you should do this or not, HP recommend it for their SAN's, though some worry about the overhead on the ESX caused by switching paths for every IO. The choice is yours, though for further reading and how to do it... | |||
