Removal and replacement procedures

Select and then perform the part removal and replacement procedures for the personal computer on which your Hardware Management Console (HMC) is based.

Depending on the system configuration, when you are directed to exchange parts, run tests, or change configuration data, the interface to the managed systems will be unavailable. If possible, before starting any of these tasks, ensure that all system management tasks are completed and all critical data is backed up.

Attention:
  • Removing power from an HMC might cause loss of data on the disk drives. If power must be removed, select Power Off from the HMC user interface. This action shuts down the operating system and turns off the power to the HMC. See HMC and system power-on and power-off procedures before proceeding with any of the removal procedures.
  • The system board, adapters, memory modules, and processor modules can be damaged by electrostatic discharge. If you are directed to exchange FRUs in an HMC, see "Handling Electro-Static Discharge (ESD) Sensitive Devices " in the appropriate PC maintenance information manuals.

When you are referred to the hardware maintenance manual for the personal computer, use the hardware maintenance manual for the appropriate personal computer machine type. To find documentation about the base HMC personal computer and its components, see Equivalent maintenance information for the HMC personal computer hardware.

  7. In the Available topics box select Service/Support guide. Then click the Go icon.
  8. Click on the link that appears below Service/Support guide.
  9. Click on the file link number listed below File link. The file for the hardware maintenance manual will open.

Recovering the HMC

If the HMC has had a problem and you need to recover the HMC, see Reinstalling the HMC machine code.

Attention: This procedure will restore the HMC image onto the disk drive in the HMC personal computer. Before performing this procedure, contact HMC support and also ensure that there are backups for all critical console data.

Backing up partition profiles

Ensure that critical data that is stored on the HMC is also regularly maintained on backup media.

To back up partition profiles, see Backing up partition profiles.

HMC machine code updates

For information about updates or upgrades for the HMC machine code, see Upgrading the machine code on an HMC from Version 6 to Version 7.

Recovering an HMC after replacing a disk drive

If you have to replace a disk drive, you must recover the HMC image and restore your stored profile data. For more information, see Reinstalling the HMC machine code.

Rebuilding a Redundant Array of Independent Disks (RAID) 1 array

For information about how to rebuild a RAID 1 array on your HMC that has a failed disk drive or solid-state drive, see Rebuilding a RAID 1 array.

Performing the firmware (BIOS/VPD) update procedure (after replacing the system board)

When your replace the system board, perform the firmware update procedure for your HMC personal computer.

Attention: Refer to the information label located inside the system unit cover for any model-specific information.

To perform the firmware (BIOS/VPD) update procedure, perform the following steps:

  1. To find documentation about the base HMC personal computer and its components, see Equivalent maintenance information for the HMC personal computer hardware.
  2. Review the section in your HMC personal computer information for "Updating the firmware."
  3. Perform the procedures to update the new system board with the latest BIOS firmware.
  4. Perform the procedures to update the vital product data (VPD) information with the machine type, model, and serial number for the HMC.
  5. Return the HMC to normal operations.
