Preparing the 9040-MR9 system to permanently remove a disk drive or solid-state drive

To prepare the system to permanently remove a disk drive or solid-state drive, complete the steps in this procedure.

1. Back up the data on the drive you plan to remove depending on the operating system you are using.
   • AIX®: Ensure that all data on that drive or the array that contains the drive is backed up and removed from the drive.
     • If the drive that is being replaced is protected by Raid-5, Raid-6, or Raid-10 and the array remains functional after removing the drive, it is not necessary to back up or remove data.
     • If the drive you are removing is a mirrored drive, you must suspend mirror protection on the drive before you remove the drive. Contact your system administrator for assistance.
     • If the drives are just a bunch of disks (JBOD) or a Raid array that will not remain functional when the drive is removed (that is, Raid-0), ensure that the disks are in the defined state by completing the following steps:
       1. Remove data access methods from the JBOD or failing array (that is, file systems, databases, and so on).
       2. Delete the array.
       3. Unconfigure the JBOD.
   • Linux®: Ensure that all data on that drive or the array that contains the drive is backed up and removed from the drive.
     • If the drive that is being replaced is protected by RAID, it is not necessary to back up or remove data.
     • If the drive you are removing is mirrored, you need to break the mirror before you remove the drive. Contact your system administrator for assistance.
     • If the drives are just a bunch of disks (JBOD), ensure that the disks are in the defined state.
2. Review the drive slot and service indicator locations. The disk drive and SSD slots are located in the front of the system.

   Figure 1 and Figure 2 show the disk drive or solid-state drive slot locations and the service indicator locations for a 9040-MR9 system.

   

   

3. To prepare the system to permanently remove a drive when the system is powered off, complete the following steps:
   1. Turn on the identify LED for the drive to be removed and for the system.
      For instructions, see Identifying a part.
      Use the blue identify LED on the enclosure to locate the system. Ensure that the serial number of the system matches the serial number to be serviced.
   2. Record the position where the disk drive or solid-state drive will be permanently removed. For example, the drive slot might be P1-D3 or P2-D3.
   3. Stop the system. For instructions, see Stopping a system.
   4. If applicable, open the rack door at the rear of the system.
   5. Label and disconnect the power cords from the system unit as shown in the following figure.
      Notes:

      • This system might be equipped with two or more power supplies. If the removing and replacing procedures require the system power to be turned off, ensure that all power sources to the system are disconnected.
      • The power cord (B) is fastened to the system with a hook-and-loop fastener (A). If you are placing the system in a service position after you disconnect the power cords, ensure that you unstrap the fastener.

      Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and power cables. (L003)
4. Attach the electrostatic discharge (ESD) wrist strap.
   The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.

   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. If at any point in this service process you move away from the system, it is important to again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
