Preparing the 8408-44E or 8408-E8E system to install a disk drive or SSD with the power turned on in Linux

Learn about the steps you must complete before you install a disk drive or solid-state drive (SSD) in a system with the Linux operating system or Linux logical partition that controls the drive location powered on.

1. Ensure that the software that is required to support the feature is installed on your system. For information about software prerequisites, see the IBM® Prerequisite website. If the required system firmware, software, or fix packs are not installed on your system, go to the Fix Central website to download and install them before you continue.
2. Determine the slot in which you want to install a disk drive or an SSD. The disk drive and SSD slots are in the front of a system.
   Figure 1 shows the disk drive and solid-state drive locations and service indicators. Service indicators are located above the latch handle on the disk drives.

   Figure 1. Disk drive and solid-state drive locations and service indicators for the system

   
   Note: When you have drive slots available in a system, enclosure, or expansion unit, fill the slot positions in the system first. However, you can choose a different disk drive or solid-state drive placement that depends on your data protection strategy.
3. To identify the available slot by using the iprconfig command, complete the following steps:
   1. Log in as root user.
   2. Type iprconfig on the command line of the Linux session, and then press Enter. The IBM Power RAID Configuration Utility display is shown.
   3. Select Work with disk unit recovery from the IBM Power RAID Configuration Utility display, and then press Enter.
   4. Select Concurrent add device from the Work with Disk Unit Recovery display, and then press Enter.
      A Concurrent Device Add display, similar to Figure 2, is shown.

      e=Exit   q=Cancel   t=Toggle

   5. Type t if you want to toggle through different location code representations.
   6. Type 1 next to the location into which you want to install the disk drive or solid-state drive and press Enter. The Verify Device Concurrent Add display is shown and the service indicator flashes for the selected slot.
   7. Do not press Enter again. Follow the rest of the procedure to complete installing the drive.
4. Record the position (an available empty slot) where the new disk drive must be installed. For example, the next available disk drive or SSD slot might be P2-D3.
5. Find the package that contains the new drive.
   Attention: Drives are fragile. Handle with care.
6. Attach the electrostatic discharge (ESD) wrist strap.
   Attention:

   • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
   • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds.
7. Remove the drive from the static-protective package and place it on an ESD mat.
