Learn how to remove and replace parts on the HMC.
You can do most of the procedures for the personal computer on which your
HMC is based. This section contains instructions to help you access the procedures
that are needed for removing and replacing parts on your HMC.
Note: 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
Power off the HMC.
HMC maintenance procedures
The procedures in this section help you to perform maintenance
tasks and to install updates to the HMC.
Attention: The system
board, adapters, memory modules, and processor modules can be damaged by electrostatic
discharge. If you are directed to exchange a part in an HMC, refer to the "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 access the personal
computer hardware maintenance documentation, refer to the Equivalent maintenance information for the HMC's personal computer hardware.
System board specifications
Your
HMC system is based on one of the following personal computer machine types
and models.
- 8676 Model 22X is used for the 7310-CR2
- 8837 Model 22U is used for the 7310-CR3
- 8187 Model F4U(without POV) is used for the 7310-C03
- 8141 Model 31U is used for the 7310-C04
- 8485 Model 3AU is used for the 7310-C05
To find documentation about the base HMC personal computer and its components,
refer to
Equivalent maintenance information for the HMC's personal computer hardware.
Recovering the HMC
If the HMC has had a problem and you need to recover
the HMC, the procedure can be found in Recovering the HMC.
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.
Backup Profiles
Ensure that critical data which is stored on the HMC
is also regularly maintained on backup media. The procedure can be found in Backing
up critical HMC data.
HMC fixes
For information about getting fixes or updates for the
HMC code, refer to Fixes and upgrades.
Recovering an HMC after replacing a disk drive
If

restore your stored profile data. Go to Recovering the HMC for more information.
Performing the firmware (BIOS/VPD) update procedure (after
replacing the system board)
When your replace the system board,
you should always 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:
- To find documentation about the base HMC personal computer and its components,
refer to Equivalent maintenance information for the HMC's personal computer hardware.
- Review the section in your HMC personal computer information for "Updating
the firmware".
- Perform the procedures to update the new system board with the latest
BIOS firmware.
- Perform the procedures to update the Vital Product Data (VPD) information
with the machine type, model, and serial number for the HMC.
- Return the HMC to normal operations.
