SSD failure
FortiGate-6501F or 6301F HA clusters support SSD (log disk) failover. SSD failover is disabled by default. You can use the following command to enable SSD failover:
config system ha
set ssd-failover enable
end
If SSD failover is enabled, if an SSD on the primary FortiGate-6501F or 6301F fails, an HA failover occurs and the FortiGate-6501F or 6301F with operating SSDs becomes the primary.
If an SSD fails on the secondary FortiGate-6501F or 6301F, its status in the cluster does not change. However, in future negotiations the FortiGate-6501F or 6301F with an SSD failure is less likely to become the primary.
