Abstract
Systems and methods provide failover operations for witness sled hardware installed in a chassis. The chassis may include data storage devices and Information Handling Systems (IHSs), each storing data redundantly to the storage devices, such as in a vSAN. A primary witness sled provides witness functions, such as arbitrating discrepancies in the redundantly stored data. The chassis includes a chassis management controller (CMC) that connects with the primary witness sled via a management signaling pathway and maintains a copy of witness transactions stored by the primary witness sled based on transactions transmitted via the management signaling pathway. The CMC generates an inventory of co-located witness sleds. Upon detecting the primary witness sled is not operational, the CMC selects a failover witness sled from the inventory of co-located witness sleds and migrates witness operations of the primary witness sled to the selected failover witness sled.
