set_func_on_present

Description

Immediately set the fan FRU's contained rotors to functional when the fan's presence has been detected and only allow the fan FRU to be set to functional when presence is detected. Using this configuration option essentially latches a nonfunctional fan FRU to nonfunctional until it has been replaced (i.e. removed and replugged). It does still allow the functional state of the rotors to continue to be updated to reflect their current functional state(s). After a fan's presence has been detected, any faults will be re-detected for that fan FRU and its contained rotors.

This attribute is optional and defaults to false, meaning a newly inserted fan will need to spin up before being set back to functional, and if it never spins up, there won't be additional errors.

Attribute Value(s)

bool (default = false)
