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 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.
3.1.9 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.
Note –
In a midrange server, you cannot use DR commands to replace a system
board. Instead, turn off the power of all domains, and then replace the target system
board.
To replace a system board in a domain, first delete the target system board from the
domain by using the
deleteboard
(8) command to make the PSB replaceable. Next,
replace the PSB with a new one, and then add the target system board to the
domain.
For details of the conditions and actions for executing the
deleteboard
(8)
command, see Section 3.1.7, “Deleting a System Board” on page 3-17 . For details of
the conditions and actions for executing the
addboard
(8) command, see
Section 3.1.6, “Adding a System Board” on page 3-15 .
