Fortigate option to bypass hardware comparison for HA

on August 15th, 2018 by Hades | No Comments »

Today I had an issue while configuring two 200B’s in an HA configuration. This usually takes about 2 minutes and is extremely easy. Unless your hardware doesn’t match. HA requires that hardware matches on the two different units. When these were purchased the hardware did match, but at some time in the past, one was RMAed and we received one with a hard drive. This broke the HA capability.

The error I kept seeing was about the hardware not being the same. The error was: “slave and master have different hdisk status. Cannot work with HA master. Shutdown the box! The system is halted.”

This command can get you past that:
exec ha ignore-hardware-revision enable

This will allow the HA cluster to ignore the hardware-revision for the frigates and come up.

There are a lot more things that will cause problems, for example, if your drives have been formatted with a previous version of fortios. You might need to run :

exe formatlogdisk
