I wanted to make sure that all the VM’s living on vSanDatastore were protected by the vSAN storage policy. I wrote a quick PowerCLI script to do this:

$VMlist = get-datastore vsandatastore | get-vm

foreach ($VM in $VMlist)
{
Get-VM -Name $VM | Set-SpbmEntityConfiguration -StoragePolicy $StoragePolicy
}

 

Using vSAN RVC to learn more about your vSAN environment

To access the vSAN RVC, simply ssh to your vCenter server appliance and run:

rvc root@localhost

This will drop you into the RVC shell once you enter the root password: Continue reading “Using vSAN RVC to learn more about your vSAN environment”

Using PowerCLI to remotely execute esxcli commands

First, make sure you’re using a version of PowerCLI that supports the get-esxcli cmdlet. In this case, I used a fresh install of PowerCLI 5.5.

First, get-esxcli needs to be run against a single host individually, you can loop through you’re hosts later, but again, one at a time. So I did:

$getcli = Get-EsxCli -VMhost vmhost.domain.local

In my case, I wanted to remove a “greyed out” NFS mount, and in esxcli, I would run: Continue reading “Using PowerCLI to remotely execute esxcli commands”
