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

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

You must have already completed the procedure Removing a PCI adapter contained in a cassette from the expansion unit with the power on in Linux to have the slot powered off.

Note: 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, follow the steps in Installing a PCI adapter contained in a cassette with the power on in the Linux environment.

To replace an adapter with the power on in Linux, do the following steps:

  1. If the adapter needs to be placed in the PCI adapter cassette, see PCI adapter single-width and double-width cassettes.
  2. At the back of the system, lift the cassette cover flap and identify the cassette slot you want to use.
  3. 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.
  4. Enter drmgr to enable an adapter to be replaced:
    For example, to replace the PCI adapter in slot U7879.001.DQD014E-P1-C3 enter: 
    drmgr -c pci -r -s locationcode
  5. Follow the instructions on the display to complete the task. When you are instructed to insert the adapter in the adapter slot, see Installing a PCI adapter cassette.
  6. Enter lsslot to verify that the slot is occupied.

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

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