HP Integrity rx7620 Server - User Service Guide, Sixth Edition

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 enables future OLAR operations to succeed on this PCI slot.
IMPORTANT: The installation process varies depending on what method for installing the PCI
card is selected. PCI I/O card installation procedures should be downloaded from the HP website
at http://docs.hp.com. Background information and procedures for adding a new PCI I/O card
using online addition are found in the Interface Card OL* Support Guide.
PCI I/O OL* Card Methods
There are three methods for performing OL* operations on PCI I/O cards.
pdweb
The Peripheral Device Tool (pdweb) web-based method of performing
OL*.
olrad
The command line method of performing OL*.
Attention Button The hardware system slot based method of performing OL*.
Prerequisites for Adding a PCI I/O Card Using the Attention Button
The prerequisites for this procedure are as follows:
• 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.
• For details on card installation, see the host bus adapter (HBA) documentation.
• To determine the status of all the PCI I/O slots, run the olrad -q command.
• Before attempting to insert a PCI I/O card into the PCI-X card cage assembly backplane slot,
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.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can 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 online add or replacement (OLAR). The attention button
is also referred to as the doorbell.
To add a PCI card, follow these steps:
1. Remove the top cover.
2. Remove the PCI bulkhead filler panel.
3. Flip the PCI manual retention latch (MRL) for the card slot to the open position. See Figure 3-8.
4. Install the new PCI card in the slot.
NOTE: To properly seat the card into the backplane, apply slow, firm pressure.
5. Flip the PCI MRL for the card slot to the closed position.
CAUTION: Working out of sequence or not completing the actions within each step can
cause the system to crash.
Do not press the attention button until the latch is locked.
6. Press the attention button.
The green power LED starts to blink.
