Hot-Pluggable Pci Adapter - IBM pSeries 690 User Manual

Hot-Pluggable PCI Adapter

Before performing the following procedure, read "Safety Notices" on page ix.
Attention: The Linux operating system does not support these hot-plug procedures. Also, Linux does not
support hot-plugging any hot-pluggable PCI adapters. Systems with Linux installed on one or more
partitions must be shut down and powered off before replacing any PCI adapter assigned to a Linux
partition. Follow the non-hot-pluggable adapter procedures when replacing a PCI adapter in any partition
with Linux installed.
The following hot-plug procedures take you through removing and replacing hot-plug PCI adapters using
software that presents procedures on your display. The LEDs on a PCI adapter cassette are described in
either your installation guide or service guide.
Removing and Replacing a Hot-Pluggable PCI Adapter
Notes:
1. Use this procedure only when you are replacing an adapter with an identical adapter. If you are
replacing an adapter with an adapter that is not identical to the adapter removed, go to "Removing and
Replacing a Hot-Pluggable PCI Adapter," and then to "Installing a New Hot-Pluggable PCI Adapter" on
page 196.
2. When a system containing a defective adapter is booted, the system considers that the PCI slot is
empty, and adapter LEDs do not light. Under this condition, it is safe to remove the adapter from the
system at this time.
To replace an adapter, perform the following steps:
1. Determine the slot from which you are removing the adapter.
2. Ensure that any processes or applications that might use the adapter are stopped.
Note: Removing a hot-pluggable PCI adapter requires the system administrator to take the PCI
adapter offline before performing any PCI adapter hot-plug procedures. Before taking an
adapter offline, the devices attached to the adapter must be taken offline as well. This action
prevents a service representative or user from causing an unexpected outage for system
users.
For additional information about taking an adapter offline or removing it from the system
configuration, see the AIX System Management Guide: Operating System and Devices.
Documentation for the AIX operating system is available from the IBM Eserver pSeries
Information Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. Select
AIX documentation. The AIX Documentation CD contains the base set of publications for the
operating system, including system-management and end-user documentation.
3. Log in as root user. If the system is a partitioned system, log in as root user on the partition that has
the adapter assigned to it.
4. At the command line, type smitty.
5. Select Devices.
6. Select PCI Hot Plug Manager.
7. Select Unconfigure a Device and press Enter.
8. Press F4 to display the Device Names menu.
9. From the menu, select the adapter you are removing.
10. If you are replacing the adapter, go to step 11 on page 195. If you are not replacing the adapter, do
the following:
a. Use the Tab key to answer NO to Keep Definition. Press Enter.
b. Go to step 12 on page 195.
