This reports the blade's lifecycle state as tracked by chassis management — where the hardware currently sits in its discover/associate/decommission lifecycle. For this blade's physical port into the chassis backplane fabric, lc tells an admin whether the blade behind this link has finished being discovered and associated with a service profile, or is still mid-lifecycle, which matters because most other properties on this row are unreliable until lc reaches a stable state. A freshly reseated blade would show lc moving through 'discovery' before settling at 'operable' once UCS Manager finishes inventorying it.
