Installing a PCI adapter contained in a cassette with the power on in the Linux environment

You can install a PCI adapter cassette in a 5802 or 5877 expansion unit that is running the Linux environment with the system power on.

1. Log in to the system console as the root user.
2. Use the lsslot tool to list the hot-plug PCI slots that are available in the server or logical partition:

   lsslot -c pci -a

   The following is an example of the information displayed by this command:

   Slot                    Description                        Devices
   U7879.001.DQD014E-P1-C1 PCI-X capable, 64 bit, 133MHz slot Empty
   U7879.001.DQD014E-P1-C4 PCI-X capable, 64 bit, 133MHz slot Empty
   U7879.001.DQD014E-P1-C5 PCI-X capable, 64 bit, 133MHz slot Empty

   Select the appropriate empty PCI slot from the ones listed by the command.
3. Remove the PCI adapter cassette from the system. Refer to Removing a PCI adapter cassette from the expansion unit.
4. Install the adapter into the PCI adapter cassette. Refer to PCI adapter single-width and double-width cassettes.
5. Ensure the lower cassette handle is pressed up toward the retainer clip. This places the adapter in the correct position to be locked in the system.
6. Enter drmgr to enable an adapter to be installed.
   For example, to install an adapter in slot U7879.001.DQD014E-P1-C3, enter:

   drmgr -c pci -r -s locationcode

   The following displays:

   The visual indicator for the specified PCI slot has been set to the 
   identify state. Press Enter to continue or enter x to exit.

7. Press Enter.

   The following displays:

   The visual indicator for the specified PCI slot has been set to the 
   action state. Insert the PCI card into the identified slot, connect any 
   devices to be configured and press Enter to continue. Enter x to exit. 

8. Install the PCI adapter cassette in the system. Refer to Installing a PCI adapter contained in a cassette.
9. Use the lsslot command to verify that U7879.001.DQD014E-P1-C3 is occupied.

   Enter lsslot -c pci -s U7879.001.DQD014E-P1-C3

   The following is an example of the information displayed by this command:

   Slot                    Description                        Devices
   U7879.001.DQD014E-P1-C3 PCI-X capable, 64 bit, 133MHz slot 0001:40:01.0
