Note – (Note 1) The time required for system board deletion processing depends on the amount of hardware resources mounted on the target system board. For this reason, much time may be required for the command to end its operation. If the system board contains kernel memory, the OS is suspended for a while.

Note – (Note 2) If the DR processing executed by the deleteboard(8) command fails, the target system board cannot be restored to the previous status. If DR processing fails, identify the cause of failure based on the error message output by the deleteboard(8) command and Solaris OS messages, and then take appropriate corrective action. Note that some errors require the domain to be rebooted.

Note – (Note 3) When a system board is forcibly deleted from a domain by the deleteboard(8) command with the -foption specified, a serious problem may occur in a process that is bound to the CPU or in accessing an I/O device. For this reason, you should avoid using the -foption for normal DR operations. When using the deleteboard(8) command with the -foption specified, be sure to check the status of the domain and application processes.

3.1.8Moving a System Board

Use the moveboard(8) command to delete a system board from the move-source domain and add it to the move-destination domain, assign it to the move- destination domain, or reserve it to be moved later.

To execute the moveboard(8) command, the system board must have been configured in or assigned to the move-source domain, and be registered in the DCL for the move-destination domain.

Use the showdcl(8) command to check whether a system board is registered in the DCL. To register a system board in the DCL, use the setdcl(8) command.

Before executing the moveboard(8) command, check the status of the move-source and move-destination domains and move-target 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 any processes that are bound to the CPU and any that are accessing 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.
