3.3 Hot-Plug Feature
Enterprise systems have extensive error detection mechanisms, and an Automatic
System Reconfiguration (ASR) feature that enables the system to be rebooted with
failed components (such as CPUs, memory, or I/O) disabled. When an error is
detected, the system can be reconfigured so that the board containing the failed
components is placed in low power mode and is no longer accessible.
Caution –
The peripheral power supply provides the precharge voltages required
for hot-plug. Do not attempt hot-plug of a system component if the power supply is
missing or inoperative. Use
prtdiag(1M)
to determine the status of the peripheral
power supply.
Caution –
If the message:
NOTICE: Hot Plug not supported in this
system
is displayed during boot, do NOT attempt hot-plug in this system or
damage to the hardware will occur.
