Checking management consoles (HMCs) and expansion racks

Procedure

  1. Only the following hardware configurations of storage facilities (SF) and management consoles (HMC) are supported. If the configuration you are installing does not match one of these configurations, stop and call the next level of support.
    • 1x1 = One HMC and one SF, (HMC is internal to SF rack-1)
    • 2x1 = Two HMCs and one SF (first HMC is internal to SF rack-1, the second HMC is "external" which means it is in a customer rack)
    • 2x2 = Two HMCs and two SFs (first HMC is internal to SF1, the second HMC is internal to SF2)
    Note: If your existing storage facility is a 2x1 and you will be installing a second SF, you will be instructed how to discontinue the existing second HMC so the new HMC in the second SF can take its place.
  2. Select the following condition that applies to your installation. This new storage facility (SF) will be:
    • The first SF in a new storage complex. Go to step 5.
    • The second SF connected to the first SF in an existing storage complex. Go to the next step
  3. Determine the total number of HMCs in the existing storage complex that are already available for use.

    Select the condition that applies:

  4. The existing external HMC2 must be discontinued. The HMC2 code objects on HMC1 and SF1 LPARs must be reset so the new HMC2 can be installed..
    1. Consult your next level of support for this storage model. After you complete that procedure, return here and go to the next step.
  5. Does the new storage facility to be installed have one or more storage expansion racks?
