Cluster: Troubleshooting an Issue Using Failover Cluster Manager Cluster Events

When we run into issues the first thing we can do is poll the nodes via the Cluster Events log in Failover Cluster Manager (FCM).

1. Open Failover Cluster Manager
2. Click on Cluster Events in the left hand column
3. Click on Query
• 
4. Make sure the nodes are ticked in the Nodes: section
5. In the Event Logs section:
• Microsoft-Windows-Cluster*
• Microsoft-Windows-FailoverClustering*
• Microsoft-Windows-Hyper-V*
• Microsoft-Windows-Network*
• Microsoft-Windows-SMB*
• Microsoft-Windows-Storage*
• Microsoft-Windows-TCPIP*
• Leave all defaults checked
• OPTION: Hardware Events
6. Critical, Error, Warning
7. Events On
• From: Events On: 2017-12-17 @ 0800
• To: Events On: 2017-12-18 @ 2000
8. Click OK
9. Click Save Query As...
10. Save it
• Copy the resultant .XML file for use on other clusters
• Edit the node value section to change the node designations or add more
11. Click on Save Events As... in FCM to save the current list of events for further digging

Use the Open Query option to get to the query .XML and tweak the dates for the current date and time, add specific Event IDs that we are looking for, and then click OK.

We have FCM and Hyper-V RSAT installed on our cluster's physical DC by default.

PowerShell TotD: Hyper-V Live Move a specific VHDX file

There are times when we need to move one of two VHDX files associated with a VM.

The following is the PowerShell to do so:

Poll Hyper-V Host/Node for VM HDD Paths

get-vm "*" | Select *path,@{N="HDD";E={$_.Harddrives.path}} | FL

Move a Select VHDX

Move-VMStorage -VMName VMName -VHDs @(@{"SourceFilePath" = "X:\Hyper-V\Virtual Hard Disks\VM-LALoB_D0-75GB.VHDX"; "DestinationFilePath" = "Y:\Hyper-V\Virtual Hard Disks\VM-LALoB_D0-75GB.VHDX"})

Move-VMStorage Docs

The Move-VMStorage Docs site. This site has the full syntax for the PowerShell command.

Conclusion

While the above process can be initiated in the GUI, PowerShell allows us to initiate a set of moves for multiple VMs. This saves on time bigtime versus mouse.

By the way, TotD means: Tip of the Day.

Thanks for reading! :)
