Panorama

Symptom

Affects adding a 2TB log disk while Panorama is in Legacy mode
After adding disk and rebooting VM, Status: Unavailable and Reason: Admin disabled message is displayed.

admin@Panorama> show system disk details

Name : sdb
State : Present
Size : 2048000 MB
Status : Unavailable
Reason : Admin disabled

Environment

Panorama-VM in Legacy Mode running PAN-OS 8.1.7.

Cause

admin@Panorama> show system state | match cfg.cms
cfg.cms.reserve: True

When cfg.cms.reserve is set to True, all new disks added will be reserved for switching to Panorama mode and made unavailable in legacy mode.

Resolution

If cfg.cms.reserve is set to 'True' then perform the following commands in the Panorama CLI:

debug panorama-vld-mgr reset-logging-disk

The above action will change the cfg.cms.reserve flag from True to False, which will allow the Panorama to use the sdb disk while in Legacy mode.

The second action is to reboot to apply the above change by using the command below.

request restart system

Note: When rebooting, the sdb disk is detected. There is a Linux make filesystem command that is run to create sdb1 partition. This may take time based on the size of the filesystem. Possibly this could take an hour or more if the filesystem is very large. The authd process doesn't start up until after these operations complete, so logging into the Panorama is unavailable.
