Symptom

Can't upgrade from PAN-OS 9.1 to PAN-OS 10.x due to hard disk issue.
Flagging on minimum hard disk size being 60GB and virtual disk size was already increased to 60 GB.

PAN-OS partition does not get expanded when virtual disk size is increased from hypervisor

Run "show system disk-space" command to verify the current disk
Shut down the PA-VM and add the new disk under Edit Setting on vSphere Client Console
Execute CLI command from VM to clone the OS image to new disk (i.e., sdb) -
```
> request system clone-system-disk target <name of new disk> 
```
clone-system-disk command will trigger a restart and upon successful conversion you will receive the disk cloning procedure completed message in console
Shut down the PA-VM to change the LUN ID. Remove the SCSI (0:0) allocation from Hard disk 1 (old) And move Hard disk 2 (new) to first.
Start the PA-VM to verify the normal operation and CLI.
To verify partition increase, run this command.
```
> show system disk-space
```

As for the public cloud environment involving AWS and Azure, the disk upgrade may not be supported, in which upgraded disk will not be reflected under PAN-OS disk-partition (show system disk-space). Deployment of new PA-VM defaulting to 60 GB disk may be required.
The disk size added in above Step 2. must be strictly 60GB.
Once the system disk usage was expanded to 60GB by executing "request system clone-system-disk" CLI command, or the PA-VM instance is initially deployed with 60GB system disk, it is no longer required to run the above steps.
