Replacing a PCI RAID and SSD SAS adapter in the 8233-E8B and 8236-E8C server with the power on in the Linux environment

You can replace a PCI RAID and SSD SAS adapter with the system power on in the Linux environment.

Use this procedure if you intend to remove a failing PCI RAID and SSD SAS adapter and replace it with the same type of adapter. The PCIe RAID and SSD SAS adapter is a double-wide adapter. Although it plugs into a single PCIe slot, two adjacent PCIe slots are required for installation.

You must have already completed the procedure Removing a PCIe RAID and SSD SAS adapter from the 8233-E8B and 8236-E8C server, with the power on in the Linux environment.

If your system is managed by an HMC, use the HMC to complete the steps for replacing the part in the system. For instructions, see Replacing a part by using the HMC.

If you do not have an HMC, complete the following steps to replace a PCIe RAID and SSD SAS adapter with the system power on in the Linux environment:

Complete the prerequisite tasks that are described in Before you begin.
Take appropriate precautions for avoiding electric shock and handling static-sensitive devices. For information, see Avoiding electric shock and Handling static-sensitive devices.
If necessary, remove the PCIe adapter from the antistatic package.
Attention: Avoid touching the components and gold connectors on the adapter.
Place the adapter, component-side up, on a flat, static-protective surface.
Label the location of each SSD as you transfer the SSDs from the replaced adapter to the same location on the new adapter you are installing. For information about replacing SSDs, see Replacing an SSD module on the PCIe RAID and SSD SAS adapter. Repeat this step for each SSD.
Run the drmgr 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 locationcode
```
Follow the instructions on the display to complete the task.
Press the adapter firmly into its connector.
Attention: When you install an adapter into the system, be sure that it is completely and correctly seated in its connector.
Carefully grasp the adapter by its top edge, and align the adapter with the expansion slot and its connector on the system backplane.
Press the adapter (A) firmly into its connector.
Attention: When you install an adapter into the system, be sure that it is completely and correctly seated in its connector.
Slide the adapter latch (B) back into place as shown in the following figure.

Run the lsslot command 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:
```
# Slot          Description             Device(s)
U7879.001.DQD014E-P1-C3 PCI-X capable, 64 bit, 133MHz slot 0001:40:01.0 
```
If you are servicing a rack-mounted system, route the cables through the cable-management arm.
Replace or close the service access cover and, if applicable, return the system to the operating position.
Verify the installed part.
- If you replaced the part because of a service action, verify the installed part. For instructions, see Verifying a repair.
- If you installed the part for any other reason, verify the installed part. For instructions, see Verifying the installed part.
