Removing a PCIe RAID and SSD SAS adapter from the 8233-E8B and 8236-E8C server, with the power on in the Linux environment

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

When an SSD on the PCIe adapter fails, the entire adapter must be removed from the system before replacing the individual SSD. For information about replacing SSDs, see Replacing an SSD module on the PCIe RAID and SSD SAS adapter.

If your system is managed by a HMC, use the HMC to complete the steps for removing a part from the system. For instructions, see Removing a part by using the HMC.

Note: Procedures performed on a PCIe adapter with the system power on in AIX®, also known as hot-plug procedures, require the system administrator to take the PCIe adapter offline before 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.

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

Ensure that the system meets the Prerequisites for hot-plugging PCI adapters in Linux.
Verifying that the hot-plug PCI tools are installed for Linux.
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 you are removing a failing PCIe adapter, see Identifying a failing part. If you are removing the PCIe adapter for other reasons, continue to the next step.
If you are installing, removing, or replacing a PCI adapter in a rack-mounted system, follow these steps to remove the service access cover.
1. Open the front rack door.
2. Place the system unit in the service position.
3. Remove or open the service access cover.
Determine which adapter you plan to remove.
Note: Before performing a PCI hot-plug removal of storage devices, ensure that the file systems on those devices are unmounted.
Record the slot number and location of each adapter being removed.
Note: Adapter slots are numbered on the rear of the system.
Run the drmgr command to enable an adapter to be removed:
For example, to remove 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.
Slide the adapter latch (A) into the open position, as shown in the following figure.
Figure 1. PCI RAID and SSD SAS adapter removed from the rack-mounted system unit
Carefully grasp the PCIe adapter (B) by its top edge or upper corners, and remove it from the system. Store the adapter in a safe place.
If you are removing a PCIe adapter as part of another procedure, return to that procedure. If not, continue to the next step.
If you plan to replace an adapter into the vacated slot, go to Replacing a PCI RAID and SSD SAS adapter in the 8233-E8B and 8236-E8C server with the power on in the Linux environment; otherwise, continue with the next step.
Seal the expansion slot using an expansion-slot cover.
Replace or close the service access cover and, if applicable, return the system to the operating position.
