3.2.2 Functions That are Used for Partition Configuration - Reserved SB (1/6)
Reserved SB Function

 This function automatically disconnects a failed SB, incorporates a spare SB that has been
implemented in advance, and restarts the PPAR block.
•The SB resources are not degraded, and the partition can be recovered quickly.
•In a partition that has only one SB, even if the SB fails (or it is degraded), the partition can be recovered.
During operation of a partition, an SB in the partition can be specified as a Reserved SB.

An SB that is used in a partition of a test environment during normal operation can be incorporated in a
partition of the production environment as a Reserved SB if a failure occurs.
2800B2/2800B3 is not supported.
