VMware – Error when using ‘Erase Partition’ on (vSAN) Storage Device – Failed to update disk partitions

I’ve been going through upgrades in the homelab and one of the changes has been to prepare for destructing an existing vSAN cluster and creating a new vSAN cluster. While going through vSAN ESA configuration, disks were not showing as available, I needed to go in and delete the existing partitions for the old vSAN cluster.

When in vSphere from a host and attempting to ‘Erase Partition’ from a storage device, we encounter the following error, below that is the error in Tasks.

SSH into the host and run the following command to verify disks are still part of a vSAN Disk Group

esxcli vsan storage list

In my case, I had all 3 disks appear, the following command removes the disks from the group. First you will need to obtain the VSAN Disk Group UUID

esxcli vsan storage remove -u <VSAN Disk Group UUID>

After running the command it will take you back to CLI prompt and you can confirm the disk group is empty by re-running the first command ‘esxcli vsan storage list’

Go back into the Storage Devices and retry the Erase Partition, I live dangerous so I did all 3 at once 🙂

It completed, validated in Tasks that partitions were updated succesfully.

Let the vSAN configurations continue.

NSX-T 3.2.1 – Error: Failed to fetch System details.

Running VMware NSX-T 3.2.1 on a clean install, no previous upgrade. Home lab is not sitting around doing much other than whatever idle tasks might be going on with the appliance. I decided to log in and BAM! The system section was not loading

Error code: 513002

Under System>>Configuration the following error would appear

I was able to navigate to check the basic health of my managers, and checked ‘View Details’ for each one; everything was up, all green, and space utilization looked good.

From the VM console logged in as admin, I tried ‘restart services controller ‘and no success.

While troubleshooting and looking for KBs and forums on the web, when running ‘get managers’ from admin console, one of my managers was in Standby, but then there was some intermittent activity where all went into Standby for a brief moment.

Not just this happening but my Appliances GUI was also now switching between ‘Healthy’ & Degraded.

Next step was to reboot one appliance at a time, which did not seem to fix the issue.

After taking a break and happen to be doing something else in the home lab, I had to shut down and restart the vCenter, well I happen to check later on in the day and NSX was able to load with no problems.

I’m going to keep this up in the event the issue comes around, I plan on updating.
