This chapter addresses the following topics:

• OL* Driver Scripts
Attention Button Actions
When you press the Attention Button, the system generates a POWER_OFF event in the following
cases:
• The slot is occupied, no drivers are attached, and the Attention Button event is a
NORMAL_REMOVAL event.
• The slot is occupied, drivers are attached to the slot, the drivers are suspended, and the
Attention Button event is a NORMAL_REMOVAL event.
• The hotplugd daemon powers off the slot if you see the following message in the hotplugd
log file: “Dropping AB Event, received, while processing another event
on the slot, slot would be POWERED-OFF”.
The Attention Button event is an INSERTION_POWERED event.
Attention Button Events
The following are Attention Button events:
INSERTION_UNPOWERED A card is inserted, the slot is unpowered
INSERTION_POWERED A card is inserted, the slot is powered
NORMAL_REMOVAL A normal hotplug removal
SURPRISE_REMOVAL Surprise card removal; for example, the latch is opened when the
power is ON
FREQ_MISMATCH OL* failed because the frequency at which the card can operate is
not compatible with the current bus frequency
MODE_MISMATCH OL* failed because the mode at which the card can operate is not
compatible with the current bus mode; for example, a PCI card
running on a PCI-X bus
POWER_FAULT Device power fault
