Unable to Configure RAID with Different SSD Drive Models on PA-5000 Series Firewalls

Issue

A PA-5000 Series firewall needs to be configured for RAID 1, but the device has mismatched SSD drive models. When the second drive is inserted into the drive bay and the device is powered on, it does not boot into the maintenance mode.

The RAID details on the device do not show the second drive mirroring or sync status, as shown below:

Resolution

The Palo Alto Networks PA-5000 Series platform must have identical SSD drive models for RAID 1 configuration. An example of the RAID details on a properly configured device is shown below:
