Replacing A System Board - Fujitsu SPARC Enterprise M4000 Features Manual

Note – (Note 1) The time required for system board deletion processing in the
move-source domain depends on the amount of hardware resources mounted on the
target system board. Moreover, in the system board addition processing in the
move-destination domain, the system board to be added is first diagnosed, and then
added to the domain. For this reason, much time may be required for the command
to end its operation. Oracle Solaris OS is suspended for a while when the system
board includes kernel memory.
Note – (Note 2) If the DR processing executed by the moveboard(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
moveboard(8) command and Oracle Solaris OS messages in the move-source and
move-destination domains, and then take appropriate corrective action. Note that
some errors require one of the domains to be rebooted.
Note – (Note 3) When a system board is forcibly deleted from the move-source
domain by the moveboard(8) command with the -f option 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 -f option for normal DR
operations. When using the moveboard(8) command with the -f option specified,
be sure to check the status of the move-source domain and application processes.
Note – (Note 4) You can execute the moveboard(8) command on a source domain
or a destination domain that is not running. When the source domain is running, the
moveboard(8) command with "-c configure" or "-c assign" will succeed only
if the following Oracle Solaris Service Management Facility (SMF) services are active
on that domain:
- Domain SP Communication Protocol (dscp)
- Domain Configuration Server (dcs)
- Oracle Sun Cryptographic Key Management Daemon (sckmd)

Replacing a System Board

Use the deleteboard(8) and addboard(8) commands to replace a system board.
Use them to replace, add, or delete such hardware resources as the CPU, memory,
and I/O devices, or replace the PSB of a CMU or IOU.
