    Figure 1. Window: PowerControl switch details
    Window: PowerControl switch details
  2. Description: Verifies that Storage Facility powerControlMode is set to REMOTE or LOCAL. Displays as FAILED in the main panel when:
    • powerControlMode attribute is equal to 0 (local)
    • powerControlMode attribute is less than -1 and greater than 5 (indicates 'unknown' state)
  3. Action:
    1. For Model 941: At the upper left rear of Rack-1, observe the Local remote switch card white Local/Remote switch. It should be in the Remote position (up). It should be in the local position (down) only if directed by next level of support or an isolation MAP for the special case where the management console could not control the storage facility power.
      • If the state is displayed as LOCAL, observe the white local remote switch position.
        • If the white switch is in LOCAL (down), complete the service action that had you set it to local. If there is no service action in progress, reset the switch back to REMOTE.
        • If the white switch is in REMOTE (up), there is a problem with the physical setting of the switch not agreeing with the setting reported by the code. Call next level of support.
      • If the state is displayed as REMOTE, this is correct if the white switch is in the REMOTE (up) position. If the white switch is in the LOCAL (down) position, call the next level of support.

    2. For Model 951: At the upper left rear of Rack-1, observe the Local remote switch card white Local/Remote switch. It should be in the Remote position (right). It should be in the local position (left) only if directed by next level of support or an isolation MAP for the special case where the management console could not control the storage facility power.
      • If the state is displayed as LOCAL, observe the white local remote switch position.
        • If the white switch is in LOCAL (left), complete the service action that had you set it to local. If there is no service action in progress, reset the switch back to REMOTE.
        • If the white switch is in REMOTE (right), there is a problem with the physical setting of the switch not agreeing with the setting reported by the code. Call next level of support.
      • If the state is displayed as REMOTE, this is correct if the white switch is in the REMOTE (right) position. If the white switch is in the LOCAL (left) position, call the next level of support.
