Note – (Note 3) If a system board has been forcibly added to a domain by the addboard(8) command with the -foption specified, normal operation of all added hardware resources may be disabled. For this reason, you should avoid using the -foption for normal DR operations. After adding a system board by using the addboard(8) command with the -foption specified, be sure to check the status of the added system board and the devices on the system board.

3.1.7Deleting a System Board

Use the deleteboard(8) command to delete a system board from a domain and assign it to the system board pool. If you specify the -c reserve option, the action takes place the next time the domain is powered off or rebooted.

Before executing the deleteboard(8) command, check the status of the target domain and system board, and the device usage status on the system board. You must determine whether you can perform the DR operation according to the status of the domains and system board, and the device usage status on the system board. You must also stop the processes that are bound to the CPU and the accessing of I/O devices to prepare for system board deletion.

If the system board to be deleted is a kernel memory board, check the status and memory size of the system board to which kernel memory is to be moved.

The following examples show the format and options of the deleteboard(8) command.

deleteboard [[-q] -{yn}] [-f] [-v] [-c disconnect] xsb [xsb...] deleteboard [[-q] -{yn}] [-f] [-v] -c unassign xsb [xsb...] deleteboard [[-q] -{yn}] [-f] [-v] -c reserve xsb [xsb...] deleteboard -h
