Installing a front drive in the 8001-12C system
Follow these steps to install a front drive in the IBM® Power® System S821LC (8001-12C) system.
Before you begin
You can install SATA and SAS front drives with the system powered on and running.
When installing NVMe drives, the system needs to be powered down; for instructions, see Stopping the 8001-12C, 8001-22C, 8005-12N, or 8005-22N system.
Procedure
- 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.
- Unlock the drive bay handle (B) by pushing in the handle release
(A) as shown in Figure 1. The handle
(B) snaps out towards you. If the handle does not snap out all the way, the
drive does not slide out of the system. Figure 1. Removing a drive

- If you are installing more than one drive, remove those drive trays.
- For 3.5-inch drives, remove the plastic filler from the carrier. For 2.5-inch drives in a 3.5-inch opening, there is a 2.5-inch tool-less drive carrier.
- Install a drive into the tray. Orient the drive such that the connectors are pointing to the rear of the drive.
- A 3.5-inch drive fills the tray, as shown in Figure 2. Fasten the drive to the sides of the tray with four screws (two screws on each side).Figure 2. Mounting the 3.5-inch drive in the tray

- A 2.5-inch drive slides into the rear of the tool-less drive carrier.
- Turn the tray upside down as shown in Figure 3.
- Open the retention spring (B) as shown in Figure 4.
- Place the 2.5-inch drive (A) into the tray, aligning the pins with the screw holes in the drive.
- When the pins are aligned, close the retention spring, allowing the pins to secure the drive in the tray.
- Turn the tray right side up.

- A 3.5-inch drive fills the tray, as shown in Figure 2. Fasten the drive to the sides of the tray with four screws (two screws on each side).
- Support the drive by the bottom as you position the drive, and insert it
into the drive slot. Important: Ensure that the drive is fully seated and is all the way into the system.
- Lock the drive bay handle (A) by pushing in the handle release as shown
in Figure 5. Figure 5. Disk drive lock detail

- If you installed an NVMe drive, power the system back on. For instructions, see Starting the 8001-12C, 8001-22C, 8005-12N, or 8005-22N system.
- Configure the installed drive for your environment. After you insert the new drive, you need to rescan for the device.
- Ubuntu Linux operating system
- To run the rescan-scsi-bus command in the Ubuntu Linux operating system, log
in to the system as the root user, and run the following command:
rescan-scsi-busThe rescan-scsi-bus tool is available in the scsitools package; install the package by using the following command:sudo apt-get install scsitools - Red Hat Enterprise Linux (RHEL) version 7.2
- To run the rescan command in the REHL version 7.2 operating system, log in to the system as the
root user, and run the command:
rescan-scsi-bus.sh -aThe rescan-scsi-bus tool is available in the sg3_utils package; install the package by using the following command:yum install sg3_utilsYou can also want to refer to: Adding a Storage Device or Path.
- Load or restore data from your backup media.
