Hot-Pluggable PCI AdapterBefore 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 notsupport hot-plugging any hot-pluggable PCI adapters. Systems with Linux installed on one or morepartitions must be shut down and powered off before replacing any PCI adapter assigned to a Linuxpartition. Follow the non-hot-pluggable adapter procedures when replacing a PCI adapter in any partitionwith Linux installed.The following hot-plug procedures take you through removing and replacing hot-plug PCI adapters usingsoftware that presents procedures on your display. The LEDs on a PCI adapter cassette are described ineither your installation guide or service guide.Removing and Replacing a Hot-Pluggable PCI AdapterNotes:1. Use this procedure only when you are replacing an adapter with an identical adapter. If you arereplacing an adapter with an adapter that is not identical to the adapter removed, go to “Removing andReplacing a Hot-Pluggable PCI Adapter,” and then to “Installing a New Hot-Pluggable PCI Adapter” onpage 136.2. When a system containing a defective adapter is booted, the system considers that the PCI slot isempty, and adapter LEDs do not light. Under this condition, it is safe to remove the adapter from thesystem 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 PCIadapter offline before performing any PCI adapter hot-plug procedures. Before taking anadapter offline, the devices attached to the adapter must be taken offline as well. This actionprevents a service representative or user from causing an unexpected outage for systemusers.For additional information about taking an adapter offline or removing it from the systemconfiguration, see the AIX System Management Guide: Operating System and Devices.Documentation for the AIX operating system is available from the IBM Eserver pSeriesInformation Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. SelectAIX documentation. The AIX Documentation CD contains the base set of publications for theoperating 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 hasthe 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 135. If you are not replacing the adapter, dothe following:a. Use the Tab key to answer NO to Keep Definition. Press Enter.b. Go to step 12 on page 135.134 Eserver pSeries 655 User’s Guide
