• Once the BIB (Boot-Is-Blocked) state is set in the nPartition, virtual partitions will not be able to boot up
until all the virtual partitions have been shutdown and the Monitor rebooted. In other words, once there
is a pending reboot for reconfiguration (RFR) within the given nPartition, no virtual partitions can be
rebooted until all the virtual partitions within the given nPartition are shut down and the involved vPars
Monitor is rebooted. This implies that the target virtual partition of the vparload, vparboot, and
vparreset commands will not boot until all virtual partitions within the nPartition have been shut down
and the vPars Monitor is rebooted.
• If any of the following conditions occur, the OS must be booted in nPars mode:
— An nPartition is reconfigured, by adding, deleting, or moving CPUs or cells,
— The nPartition’s NVRAM is cleared, or
— Hyperthreading is turned on for the first time.
• For more information on using the -R and -r options of the shutdown and reboot commands used in a
RFR, see “shutdown and reboot commands” on page 26.
• For more information, see “Shutting Down or Rebooting the nPartition (OR Rebooting the vPars Monitor)”
on page 162 and the vPars Monitor command “reboot [mode]” on page 133.
