Replacing a PCI adapter contained in a cassette from the expansion unit with the power on in AIX

You can remove or replace a PCI adapter cassette from the 5802 or 5877 expansion unit that is running the AIX® operating system with the system power on.

Before you begin: Prepare to replace a PCI adapter cassette. See Preparing to install, remove, or replace a PCI adapter cassette.

Important:

Use this procedure if you intend to remove a failing PCI adapter and replace it with the same type of adapter. If you plan to remove a failing adapter and leave the slot empty, see Removing a PCI adapter contained in a cassette from the expansion unit with the power on in AIX.
Do not use this procedure to remove an existing adapter and install a different type of adapter. To install a different adapter, remove the existing adapter as described in Removing a PCI adapter contained in a cassette from the expansion unit with the power on in AIX, and then install the new adapter as described in Installing a PCI adapter contained in a cassette with the power on in the AIX environment.
Procedures performed on a PCI adapter with the system power on in AIX, also known as hot-plug procedures, require the system administrator to take the PCI adapter offline prior to performing the operation. 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.

To replace an adapter, do the following steps:

Determine the location of the PCI adapter in the system.
Record the slot number and location of each adapter being removed.
Note: Adapter slots are numbered on the rear of the system unit.
Ensure that any processes or applications that might use the adapter are stopped.
Follow these steps to replace a PCI adapter using the PCI Hot-Plug Manager menu in the AIX Diagnostic tools:
1. Enter the system diagnostics by logging in as root user or as the celogin user, type diag at the AIX command line.
2. When the DIAGNOSTIC OPERATING INSTRUCTIONS menu displays, press Enter.
3. At the FUNCTION SELECTION menu, select Task Selection, then press Enter.
4. At the Task Selection list, select PCI Hot Plug Manager.
5. Select Unconfigure a Device, then press Enter.
6. Press F4 (or Esc +4) to display the Device Names menu.
7. Select the adapter you are removing in the Device Names menu.
8. Use the Tab key to answer YES to Keep Definition. Use the Tab key again to answer YES to Unconfigure Child Devices, then press Enter. The ARE YOU SURE window displays.
9. Press Enter to verify the information. Successful unconfiguration is indicated by the OK message displayed next to the Command field at the top of the screen.
10. Press F3 (or Esc +3) twice to return to the Hot Plug Manager menu.
11. Select Replace/remove PCI Hot Plug adapter.
12. Select the slot that has the device to be removed from the system.
13. Select Replace. A fast-blinking amber LED located at the back of the machine near the adapter indicates that the slot has been identified.
14. Press Enter. This places the adapter in the action state, meaning it is ready to be removed from the system.
Label, and then disconnect all cables attached to the adapter you plan to remove.
Remove the PCI adapter cassette from the system. Refer to Removing a PCI adapter cassette from the expansion unit.
Place the cassette with the cover facing up on an approved ESD surface.
Install the adapter into the PCI adapter cassette. Refer to PCI adapter single-width and double-width cassettes.
At the back of the system, lift the cassette cover flap and identify the cassette slot you want to use.
Ensure the lower cassette handle is pressed up toward the retainer clip. This places the adapter in the correct position to be docked in the system.
Install the PCI adapter cassette in the system. Refer to Installing a PCI adapter contained in a cassette.
Follow these steps to complete the PCI Hot Plug menus in the AIX Diagnostic tools and configure the device:
1. Press enter and continue to follow the instructions in the system diagnostics until you receive a message that the replacement is successful. Successful replacement is indicated by the OK message displayed next to the Command field at the top of the menu.
2. Press the F3 (or Esc+3) key to return to the PCI Hot-Plug Manager menu.

Verify the PCI adapter by using the following instructions:
1. Did you replace the adapter with the system power on?
  - Yes: Go to the next step.
  - No: Load the diagnostic program by doing the following steps:
