The hotplugd daemon handles PCI I/O events that are generated by pressing
the Attention Button corresponding to a PCI I/O slot.
If Attention
Buttons are pressed on multiple cards, the events are queued and
then executed in the order the system receives them.
If the same
Attention Button is pressed more than once after the 5 second cancel
window, the additional pushes are ignored.
This daemon invokes /usr/bin/olrad to perform the various OL* operations on the slot on
which the Attention Button has been pressed. The daemon does not
use the -f (override CRA results) option of olrad.
Normally, this daemon is started by the /sbin/init.d/pci_olar startup script at boot time.
If
an Attention Button is pressed before the startup of the daemon,
the event is dropped and no messages are logged. See the DIAGNOSTICS
section of the hotplugd manpage for messages that are logged in the system log
file or the hotplugd log file.
Currently, only the online addition and replacement functions
are supported. Online deletion is not supported.
The blinking of the power LED is not supported on all hardware
platforms.
The default location of the hotplug daemon log file is at: /var/adm/hotplugd.log
See hotplugd(1M) manpage for more details.
