About this task

Note: This process can be done concurrently with customer activity on the storage facility.

Procedure

  1. You must do these mandatory pre-checks before going to the next step:
    • The Rack-1 model must be 9A2/9B2 (dual SFI storage facility image).
    • The Rack-1 model must be 941 with RPQ for dual SFI storage facility image.
    • The RPQ only supports 50%/50% split ratio. Do not set 25%/75% or 75%/25% split ratios.
    • Any open serviceable events must be repaired before continuing.
      Note: The only exception is for serviceable events with only a DDM in the FRU list.
    • Run View storage facility state. Refer to MAP1100 View storage facility state (end of call).
    • Run CDA Pre-Verify. Refer to MAP1214 Run CdaPreVerify.
    • Each CEC enclosure (managed system) must have a minimum of 32 GB memory. Refer to MAP4120 Section-2.
  2. Display the memory and processor usage.
    1. From the navigation area, click Storage Facility Management > storage facility > Server View > server.
    2. From the bottom Task area, click Service Utilities > View/Change processor and memory allocation (Variable Image). The View/Change processor and memory allocation (Variable Image) window opens.
  3. Check the following fields for each managed system:
    • Num of Partitions = 2
    • Configurable Memory = 32xxx (minimum)
    • Configurable Processors = 4
    • SF System Memory = 32xxx (minimum)
    • SF System Processors = 4
    • Deconfig Memory = 0
  4. Check the following fields for each LPAR managed system:
    • Partition State = Running
    • IML State = IML
    • Server State = Online
  5. Click Continue.

    Window: New allocation ratio
  8. Observe the current and new ratios. Click Change ratio.
  9. Follow the status screens as the LPARs on this managed system are quiesced, shut down, activated, and resumed.
  10. When the allocation change is complete, the status screen opens and displays again.
  11. Notice that the LPAR IMAGE values for the managed system Ratio, Processor, and NVS Memory have changed.

  12. Have you already used this procedure for both CEC enclosures (managed systems) in this storage facility?
    • Yes, run View storage facility state. Refer to MAP1100 View storage facility state (end of call) and then exit this MAP.
    • No, you must return to step 1 and repeat the procedure for the other CEC enclosure.
      Note: You must repeat the pre-checks in step 1 to ensure the storage facility is in a clean state.
