1-6 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 In the example shown in FIGURE 1-3 , system board #2 is deleted fr om domain A and added to domain B.
Chapter 1 Overview of Dynamic Reconfiguration 1-7 1.2.4 Replacing a System Boar d Y ou can use DR to remove a system board from a domain and either add it back later , or replace it with another system board, provided both boar ds satisfy DR requir ements as described in this document.
1-8 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 For details of XSCF shell commands provided for DR, see Section 3.1, “How T o Use the DR User Interface” on page 3-1 . XSCF W eb is beyond the scope of this document.

Chapter 2 What Y ou Must Know Bef ore Using DR 2-5 A CPU to be deleted must meet the following conditions: ■ No running process is bound to the CPU to be deleted. If a running process is bound to the target CPU, you must unbind or stop the pr ocess.
2-6 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 ■ T o control whether a system board contains kernel memory , use one or more of the following features, which ar e described below: kernel cage, floating boar ds, and kernel memory assginment.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-7 When the kernel cage is enabled, kernel memory is assigned to system boards in the order of their addr ess spaces. The kernel cage begins in the first addr ess space (which initially corresponds to the non-floating boar d with the lowest LSB number).
2-8 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Once the copy-destination board has been selected, the Solaris OS performs a memory deletion on the selected user memory board. Then, the kernel memory on the system board to be deleted is copied into memory on the selected copy-destination system board.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-9 Deleting or moving a user memory board fails if either of the following statements is true: ■ The swap area does not have suf ficient fr ee space to save data from the user memory to be deleted. ■ There ar e too many locked or ISM pages to be covered by the memory on other system boards.
2-10 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Note – Do not move a device that is part of a redundant configuration fr om one domain to another domain. The consequences of two domains simultaneously accessing the same device through differ ent paths could be disastrous, such as data corruption.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-11 Moreover , a system board that is pooled can be assigned to a domain only when it is register ed on DCL.
2-12 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 When kernel memory is copied, the Solaris OS is temporarily suspended.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-13 operation. As a matter of course, system boards to be deleted, moved, or replaced have alr eady been register ed in the DCL.
2-14 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Note – Enable the configuration policy option when the power supply of the domain is turned off. 2.2.2.2 Floating Board Option The floating boar d option controls kernel memory allocation.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-15 2.2.2.3 Omit-memory Option When the omit-memory option is enabled, the memory on a system board cannot be used in the domain.
2-16 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Note – Enable the omit-I/O option when the system board is in the system board pool or when the system board is not connected to the domain conf iguration.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-17 If the kernel cage is disabled, the system may run more ef ficiently , but kernel memory will be spread among all boar ds and DR operations will not work on memory .
2-18 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 XSCF manages the following aspects of domain status: T o perform a DR operation for a system board, you must determine the method of DR operation according to the status of the relevant domain.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-19 The table below lists the status types available for individual management items. XSCF changes and configur es system board status accor ding to the conditions under which a system board is installed, removed, or r egistered in the DCL, or when a domain is started or stopped.
2-20 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 T o perform a DR operation for a system board, you must determine the method of DR operation according to the status of the target system boar d. Y ou can display and reference the status of each system board via a user interface provided by XSCF .

2-28 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 memory contents. Be aware that some of the total swap space may be supplied by disks that are attached to the board to be deleted. When making your assessment, be certain to also account for the swap space that will be lost.
Chapter 2 What Y ou Must Know Bef ore Using DR 2-29 For example, when a kernel memory board with memory mirr or mode enabled is deleted or moved, kernel memory is moved from the kernel memory boar d to another system board. Kernel memory is moved normally even if memory mirror mode is disabled for the move-destination system board.
2-30 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 2.5.8 Deletion of Boar d with DVD Drive T o delete the system board to which the server ’s DVD drive is connected, execute the following steps: 1. Stop the vold (1M) daemon by disabling the volfs service.

3-16 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Note – (Note 1) In the system board addition pr ocessing executed by this command, a diagnosis of the system board to be added is performed first, and then the system board is added to the tar get domain.
Chapter 3 DR User Interface 3-17 Note – (Note 3) If a system board has been forcibly added to a domain by the addboard (8) command with the -f option specified, normal operation of all added hardwar e resour ces may be disabled. For this reason, you should avoid using the -f option for normal DR operations.
3-18 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 T ABLE 3-14 Options of the deleteboard Command Option Description -q Specifies the suppr ession of output message display .
Chapter 3 DR User Interface 3-19 Note – (Note 1) The time requir ed for system board deletion pr ocessing depends on the amount of hardwar e resour ces mounted on the target system board. For this reason, much time may be r equired for the command to end its operation.
3-20 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 The following examples show the format and options of the moveboard (8) command. moveboard [[-q] -{y|n}][-f][-v][-c configure] -d domain_id xsb [ xsb ...] moveboard [[-q] -{y|n}][-f][-v] -c assign -d domain_id xsb [ xsb .
Chapter 3 DR User Interface 3-21 Note – (Note 1) The time requir ed for system board deletion pr ocessing in the move-source domain depends on the amount of hardwar e resources mounted on the target system boar d.
3-22 SPARC Enterprise Mx000 Servers Dynamic Reconfiguration User’s Guide • September 2007 Note – (Note 2) If the DR processing executed by the moveboard (8) command fails, the target system boar d cannot be restored to the pr evious status.
Chapter 3 DR User Interface 3-23 Note – (Note 1) Before r eplacing a system board, you must know the division type of the replacement-tar get PSB and the configurations and operation status of all domains to which all XSBs on the PSB belong.
