Printing and preparing the configuration for expansion unit conversion

Understand all the necessary steps to ensure that you are ready for the expansion unit conversion.

Ensure that the currently installed server and logical partitions are fully documented before the authorized service provider arrives to perform the expansion unit conversion. Make sure that these documents represent the most recent configuration of the server and that no hardware changes were made since printing the documentation. If you make changes before the service representative arrives, print the server and logical partition documentation again.

To print and prepare the configuration for expansion unit conversion, complete the following steps:

  1. Print the disk configuration status from each logical partition of the server. See Printing disk configuration status for more information.
  2. Print the parity set configuration and status from each logical partition of the server. Be sure to mark each printout with the name of the logical partition that it represents. See Printing parity set configuration and status for more information.
  3. Print the hardware resource information for each logical partition of the server. See Displaying, verifying, and printing hardware resource information for more information.
  4. Assign all unassigned I/O resources. See Assigning all unassigned I/O resources. These should be assigned to an active partition.
  5. Remove failed or nonreporting resources. See Removing failed or nonreporting resources. Use the Hardware Service Manager (HSM) on the logical partition.
  6. Print the system configuration for logical partitions. See Print the system configuration for logical partitions.
  7. Use the printouts from step 8 to determine any load-source resources in a bus that will be changing bus numbers, for instance, when a bus is converted or recabled.

    Perform the following tasks for each logical partition with a load source disk unit in a converted or recabled bus:

    1. Count one drive if the logical partition has RAID or unprotected drives.
    2. Count two drives if the logical partition has mirrored drives.
    3. Record the total number of load source disk units.
    4. Record the serial number of the load source disk (unit 1) for each converted or recabled bus.

    You will need this information when you reconfigure bus or IOP ownership.

    Example: Partition 3 has a load source redundant array of independent disks (RAID) of 1. Partition 4 has a load source mirrored value of 2. The value of Partition 3 added to the value of Partition 4 equals 3. Record 3 as the total number of load source disk units.

  8. Use the printouts from step 8 to determine the frame IDs and bus numbers associated with all hardware that is changing. This information must be given to the authorized service provider and is required for the expansion unit conversion.
  9. Follow the instructions in Changing the system value settings.
  10. Save your logical partition configuration data. To save your logical partition information, see Copying LPAR configuration.
  11. Turn off your system. See Power Off.
  12. Gather the following documents for the authorized service provider:
    System Planning Tool (SPT) output
    This document should not change as a result of the conversion.
    Disk configuration printouts for each logical partition.
    These documents should not change as a result of the conversion.
    Parity set configuration printout for each logical partition.
    These documents should not change as a result of the conversion.
    Description label locations printout for each logical partition.
    These documents should not change as a result of the conversion.
    Server configuration list printouts for each logical partition.
    This can be obtained from the Hardware Service Manager (HSM)
    Partition information printouts for each logical partition.
