2.4 System board pool management

GP7000F model 1000/2000, and PRIMEPOWER 800/1000/900/1500/2000/2500 support multiple partitions. Using the DR feature, the administrator can reconfigure the partitions dynamically and move system boards between partitions.

The administrator can also use the system board pool to reserve system boards scheduled for a move.

Note:

To create a new partition, refer to the System Console Software User's Guide (an online manual).

The system administrator can schedule the usage of the system board pool according to the system load. The system administrator picks up some boards from the system board pool, adds them to partitions for load sharing, and puts them back to the system board pool when no longer needed.

It is helpful that the administrator manage the system to ensure that boards intended for a move can be detached. Each component, CPU, I/O and memory, on such boards must meet the conditions for a successful DR operation, as described in section 2.1 "DR System Components".

The administrator can restrict the usage of memory and I/O on boards intended for a move by using the OBP environment variables described in section 2.3.2 "DR configuration and OBP (Open Boot PROM)". If it is possible, restricting I/O usage is an easier solution than redundant configuration like I/O multhipathing.
