It is advised to determine the condition of all slots run
the following command prior to using the Attention Button. This
can be accomplished using the olrad command or through the pdweb tool. For additional details of the olrad command, see Chapter 4 “olrad - Command Line Interface”, to view slot information using the pdweb tool, “Viewing
Slot Information”.

Refer to the olrad(1M) manual page and Chapter 4 “olrad - Command Line Interface”, for information on this command.
In the example above, slots 1 & 2 are occupied and
the slot power is ON, while the remaining slots are not occupied
and the power is OFF to the slot.
In the output, slots with the same bus number are treated
as shared slots.
Adding
a Card On-Line |
 |
Adding a new card to a slot is a four step process. This action
is active only when the selected slot is capable of a card addition.
Before beginning, be sure to familiarize yourself with the OL* concepts
in Chapter 1 “PCI Card OL* Overview and Concepts”.
Prerequisites for this procedure:
Drivers for the card have already been installed.
There are no drivers associated
with the slot.
The power LED is steady
OFF (some platforms may have the empty slot in ON state,
use the olrad command or the pdweb tool to power the slot OFF).
The Attention LED is steady
OFF or is BLINKing (if
a user has requested a locate of the slot).
Refer to the Host Bus Adapter
(HBA) documentation for details on card installation.
You are grounded to the chassis
of the unit.
The CRA performed while doing an Attention Button initiated
Add action is very restrictive, and the action will not complete
(it will fail) to protect critical resources from being impacted.
For finer control over CRA actions, use pdweb or the olrad command.
Replacing
a Card On-Line |
|
Prerequisites for this procedure:
The card to be replaced uses the same drivers
and is of the same type as the card being replaced
The Power LED is steady
ON.
The Attention LED is steady
OFF or is BLINKing (if
a user has requested a locate of the slot).
You are grounded to the chassis
of the unit.

| |
|
 | CAUTION: Working out of sequence, or not completing the actions
within each step, could cause the system to crash. Do not unlock
the latch until the after the Attention Button is pressed. |
|
| |
|
Press the Attention Button.
The
power LED will start to BLINK, and then turn steady OFF.
If
the power LED does not go OFF, then check the hotplugd daemon log file (default: /var/adm/hotplugd.log ) for errors, and do NOT PROCEED further.
Manually unlock the latch (if
present).1
Remove the installed card.
The
slot can be left in the power OFF condition
and the card replaced at a later time.
Install the new card into the
slot.
|
| |
|
 | NOTE: Online addition using the attention button does
not perform the pre-add sequence of olrad (olrad -a). |
|
| |
|
Press latch to the locked position
(if present).1
Press the Attention Button.
The
power LED will start to BLINK.
Wait for the power LED to stop
BLINKing2.
Check for errors in the hotplugd daemon log file (default: /var/adm/hotplugd.log )
The CRA performed while doing an Attention Button initiated
Replace action is very restrictive, and the action will not complete
(it will fail) to protect critical resources from being impacted.
For finer control over CRA actions, use pdweb or the olrad command.
1. Refer to system hardware documentation for latch instructions.
2. This is the final state of the led. The actual LED behavior
is detailed in flowcharts in “Comparing OL* Methods”.
