3.6 Replacing the Home SB No.

Partition #P: SB #a -> Partition #P: SB#c
Partition #Q: SB #b -> Partition #Q: SB#b
Partition #R: SB #c -> Partition #R:
The status transition of each partition is shown from (1) to (4) of the 'Partition status transition' in the table
below.
Partition
Partition #P
Partition #Q
Partition #R
Even if Partition #P, Partition #Q or Partition #R is running, the status of the partition will be as indicated in
(1) in the table.
No.
( 1) Partition #P, Partition #Q and Partition #R are in operation.
( 2) SB #a of Partition #P becomes faulty.
( 3) SB #a of Partition #P is disconnected and stopped. Following this, Partition #R is powered off. After
that, SB #c is removed from Partition #R configuration, and the specification of Reserved SB of
Partition #Q is canceled.
( 4) After being removed from the Partition #Q configuration, SB #c is configured as the SB of Partition
#P. Partition #P is automatically powered on and the partition begins to operate.
In the status transition of (1) to (4), SB #c is incorporated in Partition #P in place of the faulty SB #a, restarted
and it starts operating. Partition #Q is not affected. Partition #R stops and SB #c is removed from the
configuration. SB #c, which was set as a Reserved SB in (1), is cleared of this status.
The resulting status shown in 'Partition setting (after switching)'and 'Reserved SB setting (after switching)'.
After the SB switches to the Reserved SB, MMB changes its settings as shown in the table below.
Partition
Partition #P
Partition #Q
Partition #R
O: Shows the partition setting status
Partition
Partition #P
Partition #Q
Partition #R
O: Indicates the setting status of the Reserved SB (However, all are blank)
When there was a switch to the Reserved SB as mentioned above, MMB displays the following SELs.
SEL-1. SB #a was replaced with Reserved SB #c in Partition #P
SEL-2. Reserved SB #c was removed from Partition #Q
SEL-3. Reserved SB #c was removed from Partition #R
SEL-1 indicates that SB #a of Partition #P has been switched to Reserved SB #c.
The messages of SEL-2 and SEL-3 indicate that the Reserved SB setting for SB #c has been canceled, or
SB #c has been removed from the operating partition, when there was a switch to the Reserved SB #c.
The status is determined from the partition operation before add after the switching. In the above example,
since Partition #R was powered off just before SB #c was removed, you can see that SB #c has been
removed from Partition #R that is in operation.
3.6 Replacing the Home SB No.
The Socket No. of the Home SB is made as 0 and operated. This section describes the replacement of the
Home SB No., which logically replaces the physical SB0, when an SB, not being a physical SB0 becomes the
