Removing a hot-plug PCI adapter
See the information that comes with the xSeries 455 server and the following
instructions to remove an existing hot-plug PCI adapter.
Note: You must log in as a root user to issue hot-plug commands.
Attention: When you install an adapter, make sure that the adapter is
correctly seated in the connector. Improperly seated adapters might cause
damage to the PCI-X board or to the adapter.
d. Connect the cables for the adapter, if required.
e. Push down on the blue adapter guide to keep the adapter steady.
f. Close the tab; then, make sure that the adapter-retention latch clicks into
place, securing the adapter.
6. Make sure that the green power LED beside the slot in which you just installed
the adapter is now lit.
7. Save an updated listing of the installed PCI devices. For example, type the
following command:
# lspci > /tmp/lspci$$.out2
8. Compare the original and updated installation listings to confirm that the new
PCI adapter was detected and to determine the bus and slot numbers where it
is installed. For example, type the following command:
# diff /tmp/lspci$$.out1 /tmp/lspci.out2
9. Change to the directory (in /proc/bus/pci/slots) for the PCI slot that is identified
by the bus number and slot number in step 8. For example, type the following
command:
# cd /proc/bus/pci/slots/ACPI*-busnum:slotnum
which indicates that the PCI slot power is turned on:
# cat power
1. Type the following command and examine the output to verify that the
pci_hotplug and acpiphp drivers are loaded:
# lsmod
2. Type the following command and examine the output to verify that the PCI
hot-plug file system is mounted:
# mount
3. Type the following command and examine the output to determine the bus and
slot numbers for the existing PCI adapter:
# lspci
4. Type the following command to confirm that the output shows the PCI adapter
that you want to remove:
# lspci -s busnum:slotnum
5. Change to the directory (in /proc/bus/pci/slots) for the PCI slot that is identified
by busnum:slotnum in step 4. For example, type the following command:
# cd /proc/bus/pci/slots/ACPI*-busnum:slotnum
