Restore the service processor settings for a system managed by an HMC version 7, or later

After you replace the service processor assembly or time-of-day battery, complete the following procedure to restore service processor settings when your system is managed by an HMC version 7, or later.

1. Verify the following cables:
   • That the HMC cable is connected to the HMC port on the service processor assembly.
   • All system power cables are plugged into power outlets.
     Important: Do not start the system at this time.
2. Choose from the following options:
   • If you use Dynamic Host Configuration Protocol (DHCP) IP addressing, continue with step 3.
   • If you use Static IP addressing, continue with step 6.
3. Check to see if the managed system is accessible by performing the following steps:
   1. In the HMC's Navigation area, expand Systems Management.
   2. Select the managed system.
   3. In the contents area, view the status of your managed system. .

      The status of the managed system will be Pending Authentication. This indicates that the HMC's access password (to the service processor assembly) has not yet been set.

   Does the object representing the managed system with an IP address listed appear?

   • No: Go to step 4.
   • Yes: Continue with step 8.
4. Important: The next step is only applicable in a model 520, 570, or 9116-561 with customer-installed service processor cards, and is not used during a battery replacement.
5. If you are not able to access the managed system, reset the service processor network interfaces (and passwords) by doing the following:
   1. Remove the service processor assembly. Do not remove the time-of-day battery. Refer to Remove the model 285 or 520 service processor assembly, or Remove the model 570 or 9116-561 service processor assembly.
   2. Move both service processor reset toggle switches A from their current position to the opposite position.
      Figure 1. Model 520 service processor reset toggle switches

      
      Figure 2. Model 550 service processor switch

      

      To locate the reset switch for other models, see Finding part locations in the Service provider information.

   3. Replace the model 285 or 520 service processor assembly, or Replace the model 570 or 9116-561 service processor assembly.
   4. Continue with step 8.
6. If the network connection uses static IP address assignments, perform the following steps:
   1. Verify that all system power cables are plugged into power outlets.
      Important: Do not start the system at this time.
   2. Connect a client with a Web browser directly to the service processor network port using one of the following URLs:
      • https://192.168.2.147
      • https://192.168.3.147
   3. Log on to the ASMI with the user ID admin and the default password admin.
   4. If prompted, change the admin user ID's password. For details, refer to Changing the password.
   5. Configure network access using the static IP address.
      1. From the ASMI navigation area, expand Network Services.
      2. Click Network Configuration.
         • If your service processor connects to the network using a static IP address on Ethernet port HMC1, fill in the section labeled Network Interface eth0.
         • If your service processor connects to the network using a static IP address on Ethernet port HMC2, fill in the section labeled interface eth1
      3. Ensure that the following fields are filled in correctly.

         Table 1. Static IP address configuration

         Field	Value
         Configure this interface?	Selected
         Type of IP address	Static
         IP address	The service processor’s static IP address
         Subnet mask	255.255.255.0

      4. Click Continue and verify your settings on the Network Configuration panel.
      5. Click Save Settings to complete the static IP Address configuration.
         Attention: If you change the IP of the port you are currently connected to, you will loose connectivity when you save the settings. You might have to reconfigure the system you are currently using to connect. Also, you will need to log back into ASMI once connected.
   6. Continue with step 7.
7. Check if the managed system is accessible by performing the following steps:
   1. In the HMC's Navigation area, expand Systems Management.
   2. Select the managed system.
   3. In the contents area, view the status of your managed system. .

      The status of the managed system will be Pending Authentication. This indicates that the HMC's access password (to the service processor assembly) has not yet been set.

8. To set the initial password for admin, general, and the HMC access passwords, perform the following steps:
   1. In the HMC's Navigation area, expand Systems Management.
   2. Select the managed system.
   3. Select Operations > Change Password.
   4. Follow the on-screen prompts to enter any necessary passwords.
   5. Click OK.
9. Access ASMI from the HMC and reenter the following settings:
   1. Power/Restart Control
   2. System Service Aids, including Call-Home/Call-In setup
   3. System Information
   4. System Configuration, including System Name
   5. Performance Setup
   6. Login Profile
   7. Important step: Reenter the processing unit power control network identifier. For example, you would use these identifiers for the following models:
      • B4 (Model 285, 520 or 52A)
      • B2 (Model 570 or 9116-561)
      • B3 (Model 570 or 9116-561 with one or more secondary units
        Important notes:

        • The value should be overwritten and saved even if it appears to be correct for your system configuration.
        • Once you set this option, the service processor assembly will restart. After the system restarts, you will need to log into the ASMI again.

      For information on other models, refer to Changing the processing unit identifier.

10. Reenter any service processor settings that you may have set using operating system commands. You should have recorded these settings before removing the service processor.
11. Choose from the following options:
    • If you are working on a model 570 or 9116-561, continue with step 12.
    • If you are not working on a model 570 or 9116-561, you might need to update to the latest server firmware level. Refer to Server firmware fixes. Then continue with step 13.
12. Note the following:
    Important: If you replaced a service processor in a 570 or 9116-561, and the service processor that was replaced contains a later level of server firmware than you were previously using, you will need to consider some options. Refer to Table 2.

    Table 2. Options to consider after replacing a service processor that contains a higher level of server firmware than the one replaced in a model 570 or 9116-561.

    Your situation	Action
    You want to keep the server firmware level at a later level. You will need to review the HMC machine code and ensure that is equal to or greater than the server firmware level.	To determine if your HMC machine code needs to be updated, see Determining if your server firmware level and HMC machine code level are compatible.
    You want to apply an earlier level of server firmware. Note: Only apply an earlier level if there is a certification requirement to stay at an earlier level of server firmware.	Refer to Using an HMC to apply an earlier level of server firmware for a model 570 after replacing the service processor.

13. When your system goes to the recovery state, restore the logical partition profiles. Refer to Restoring profile data using the HMC.
14. Start the system or logical partition.
15. Once the system starts and the logical partitions are activated, verify the time of day for each logical partition. If necessary, set the time of day using the appropriate operating system command for each logical partition.
16. Verify the installed part.
