Removing and replacing a PCI adapter contained in a cassette in a
Linux partition that is powered on
Procedures performed on a PCI adapter in a Linux partition that is powered on, 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.
Before performing this procedure, do the following steps:
v Ensure that the system meets the “Prerequisites for hot-plugging PCI adapters in a Linux partition” on
page 122
v “Verifying that the hot-plug PCI tools are installed on the Linux partition” on page 123.
To remove and replace an adapter, do the following steps:
1. Determine the location of the PCI adapter in the system.
2. Record the slot number and location of each adapter being removed. Adapter slots are numbered on
the rear of the system unit.
3. Ensure that any processes or applications that might use the adapter are stopped.
4. Run the drmgr -c pci command to enable an adapter to be replaced:
For example, to replace the PCI adapter in slot U7879.001.DQD014E-P1-C3 run this command:
drmgr -c pci -r -s U7879.001.DQD014E-P1-C3
Follow the instructions on the display to complete the task.
5. Label, and then disconnect all cables attached to the adapter you plan to remove.
6. Lift up on the PCI adapter EMC shield (A) as shown in Figure 48 on page 111 and then rotate it up
and away from the cassette as shown in Figure 49 on page 112.
If the PCI adapter does not have an EMC shield, go to step 7.
