This enumerated value names the specific workflow currently executing for this internal backplane link, such as a link discovery or port bring-up sequence. It matters on the finite-state-machine record UCS Manager runs while it discovers, acknowledges, or brings up that internal server-side backplane link because different named workflows have different expected durations and failure modes, so knowing which one is running tells an admin what 'normal' looks like before worrying about a delay. A currentFsm value naming a discovery workflow on this link that has been running far longer than a typical discovery cycle is a concrete reason to intervene rather than wait.
