Locate VMware snapshots with PowerCLI

PowerCLI is a scripting toolkit for vSphere and vCenter within a PowerShell console. You can use it to manage and report on vSphere and vCenter servers.

Find v5 here (requires a My VMware login) or search for latest version. Launch the installer, no reboot is required.

Using PowerCLI
Once installed look for the following icon in the Apps screen.


This will launch the PowerCLI console (run as a user that has admin rights on the VMware environment. In mine LDAP authentication is enabled so I run the PowerCLI as a domain admin account.

PowerCLI Commands

connect-VIServer -server <server-fqdn> (This is required before you can run any commands. It will always try to to use SSO for connection to a vCenter server, not for ESXi hosts)

disconnect-VIServer * or Disconnect-VIServer <server-fqdn>

$global:DefaultVIServer use this command to determine what host you are connected to.

get-datacenter Get the datacenter for the the current connection

get-cluster Get the cluster for the the current connection

get-vm | Get-Snapshot | select VM,Name,Created | sort created Find all VMware snapshots that have been deteled/released once the backup is complete

get-vm | Get-Snapshot | select VM,Name,Created | Where {$ -Like “smvi*”} | sort created Find all NetApp snapshots that have been deteled/released once the backup is complete

Get-VM | Export-CSV -Path <filename.csv> Export data

NetApp CIFS shares not mounting to Windows Server 2012

The Scenario:

I have created a NetApp CIFS share that needs to be accessible on Server 2003, 2008R2 and 2012R2 servers.

The Problem:

The NetApp CIFS share connects fine on a Windows Server 2003 or 2008 machine, but when I tried on a Server 2012 R2 it wouldn’t connect and I’d get the following error:


The Solution:

The NetApp Filer had digital signing set to off, whereas Windows Server 2012 requires it by default. This mismatch causes the share failure. I was unable to enable digital signing on the NetApp due to the potential performance degradation it would have caused so the other option was to disable the digital signing requirement on Windows.

In an elevated PowerShell terminal type:

Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters” RequireSecureNegotiate -Value 0 -Force

No reboot is required.
