When SM service is active on either B0/CB0 or B1/CB0 and then the other CC is reloaded, then the issue could be hit. ‘show platform’ displays UNKNOWN for the CC that has active SM service. What happened was that on reload of the CC, shelf_mgr sent DOWN state to rack-scoped inventory on both B0/CB0 and B1/CB0 and then both databases were deleted. When the reloaded CC comes back up, the database on that CC repopulates. The database on the other CC remains empty and so ‘show platform’ displays UNKNOWN for it. The same scenario described above can apply for LCC racks. Known trigger is ECP reload
There is no workaround. To recover from this issue after the problem is hit restart shelf_mgr process where SM service is active.
If a UFC (Universal Fabric Card) crashes or is reloaded while SM reports it as unknown card type it will remain in a failed state and not boot back up until the recovery actions for CSCvr38788 is performed. This result in the loss of the fabric plane associated with the UFC. If a line cards crashes or is manually reloaded while SM reports it as unknown card type it will initially fail to reload and then go HW and SW operational after about 5 minutes. If an RP card crashes or is manually reloaded while SM reports it as unknown card type it will initially fail to reload and then go HW and SW operational after about 5 minutes.
