You can’t resize a virtual disk after adding it to a Panorama virtual appliance running on VMware vCloud Air. Because the Panorama virtual appliance allows only one log storage location, you must replace the virtual disk to modify the log storage capacity.
You will lose the logs on the existing disk when you replace it. One way to preserve the logs is to set up a new Panorama virtual appliance for the new disk (see Set Up the Panorama Virtual Appliance) and maintain access to the Panorama containing the old disk for as long as you need its logs. A second way to preserve the logs is to copy them from the old disk to the new disk. Copying can take several hours, depending on how many logs the disk currently stores, and Panorama cannot collect logs during the process. Contact Palo Alto Networks Customer Support for instructions on how to copy logs between disks. A third way to preserve existing logs is to Configure Log Forwarding from Panorama to External Destinations before you replace the virtual disk.
Replace the Virtual Disk on vCloud Air
Remove the old virtual disk. Access the vCloud Air web console and select your Virtual Private Cloud OnDemand region. Select the Panorama virtual appliance in the Virtual Machines tab. Select Actions > Edit Resources. Click x for the virtual disk you are removing.
Add the new virtual disk. Add another disk. Set the Storage to up to 8TB and set the storage tier to Standard or SSD-Accelerated. Save your changes.
Reboot Panorama. Log in to the Panorama virtual appliance. Select Panorama > Setup > Operations and Reboot Panorama.
Verify that the modified log storage capacity is correct. Log in to the Panorama virtual appliance after it reboots. Select Panorama > Setup > Management and verify that the Logging and Reporting Settings section, Log Storage field, displays the modified log storage capacity accurately.
