PCI I/O Card Installation
HP 9000 rp8420 servers implement manual retention latch (MRL) hardware for use in online add or
replacement (OLAR) operations. If an MRL is left open while the server is booting, HP-UX can incorrectly
cache PCI slot power status causing OLAR operations to fail. To prevent this situation, ensure all the MRLs
are closed before booting the server.
If OLAR reports that a slot is present and powered off, but no OLAR operations to turn power on to that slot
have succeeded even after the MRL is closed, the MRL may have been left open during boot. To clear this
condition, close the MRL for the PCI slot then power off the PCI slot using the
rad -o
command. This will
allow future OLAR operations to succeed on this PCI slot.
IMPORTANT
PCI I/O card installation procedures should be downloaded from the http://docs.hp.com Web
site. Background information and procedures for adding a new PCI I/O card using online
addition are found in the Interface Card OL* Support Guide.
Prerequisites for Adding a PCI I/O Card Using the Attention Button
The prerequisites for this procedure are:
•
Drivers for the card have already been installed.
•
There are no drivers associated with the slot.
•
The green power LED is steady
OFF
. Should the empty slot be in the
ON
state use the olrad command or
the pdweb tool to power the slot
OFF
.
•
The yellow attention LED is steady
OFF
or is blinking if a user has requested the slot location.
•
Refer to the host bus adapter (HBA) documentation for details on card installation.
•
Run the
olrad -q
command to determine the status of all the PCI I/O slots.
•
Obtain a copy of the interface card guide for instructions on preparing the operating system for the online
addition of the PCI I/O card before attempting to insert a PCI I/O card into the PCI-X card cage assembly
backplane slot.
CAUTION
Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
This procedure describes how to perform an
online addition
of a PCI card using the attention button for
cards whose drivers support OLAR. The attention button is also referred to as the doorbell.
Step 1.
Remove the top cover.
Step 2.
Remove the PCI bulkhead filler panel.
Step 3.
Flip the PCI manual release latch for the card slot to the open position. See Figure 2-18.
Step 4.
Install the new PCI card in the slot.
NOTE
A slow, firm pressure is needed to properly seat the card into the backplane.
Step 5.
Flip the PCI manual release latch for the card slot to the closed position.
