Replacing a drive on module in the 8001-22C or 8005-22N system

Learn how to replace a drive on module (DOM) in the IBM® Power® System S822LC for Big Data (8001-22C) or the IBM CS822 (8005-22N) system.

1. 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.
2. Install the DOM into the system backplane, in positions (A), as shown in Figure 1. Depending on the DOM model, you may also have to plug in a small power cord for the DOM. Ensure you plug the connectors in properly.

3. Prepare the system for operation. For instructions, see Preparing the 8001-22C system for operation after you remove and replace internal parts.
4. 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:
