When the domains are first powered on, four COD permits are assigned to COD

CPUs in domain 0 and two to domain 1. The remaining four COD permits are

available on a first-come, first-served basis to all four domains (0, 1, 2, and 3).

Notes on Domain Configuration

Note the following points when you configure domains using resources on COD

boards.

To set the COD board to Uni-XSB

■

When 3 COD permits or less are allocated to a COD board, there are CPUs which

can't be used in Uni-XSB.

To use these CPUs, you need to purchase the COD permits, and then perform

either of the following operations:

Power off the domain which contains the relevant Uni-XSB and power it on

■

again.

You can't add the CPU by rebooting the domain.

Use DR to once detach the relevant Uni-XSB from the domain and then

■

remount it to the domain.

For details on DR, see the SPARC Enterprise M4000/M5000/M8000/M9000

Servers Dynamic Reconfiguration (DR) User's Guide.

Note – Although the domain reboot occurred due to the reasons such as CPU

failure, the server doesn't automatically start to use the unused CPU instead of the

failed CPU.

To set the COD board to Quad-XSB

■

Since the CMU is divided into four, you can use the resource on 1 Quad-XSB per

COD permit. You can't use the remaining resources on 3 Quad-XSBs.

Headroom Management

Headroom is the capability to use up to four COD CPUs per server without a

sufficient number of COD permits to cover their use. Headroom allows you to

activate a COD board under these conditions:

As a hot spare to replace a failed system board

When you intend to purchase the appropriate number of COD permits, but need
