Correcting a connection problem between the HMC and a managed system

Use this procedure in the following situations:

• You have a new HMC
• You have a new system
• You moved your system to a different HMC

If your system was previously connected to the same HMC and is now in No connection state, refer to Correcting a No connection state for a managed system.

1. Choose from the following options:
   • If the system uses DHCP addressing, go to step 2.
   • If the system uses Static addressing, go to step 6.
   Note:
   To find out if your system uses DHCP or Static addressing, perform one of the following:

   • Use the ASMI by selecting Network Services -> Network Configuration and viewing whether the IP address field shows Static or Dynamic.
   • If you have a control panel, use function 30.
2. If your system uses DHCP addressing, add a system automatically by issuing the following command: mksysconn -o auto.

   Does the system appear?

   • Yes: This ends the procedure.
   • No: Continue with step 3.
3. Check for network problems, cables, switches, link lights on the service processor, and so on.

   Was there a problem?

   • Yes: Correct the problem and return to step 2.
   • No: Continue with step 4.
4. Reset the service processor to force it to request a new IP address. Refer to Resetting the service processor.
5. Did resetting the service processor resolve the problem?
   • Yes: This ends the procedure.
   • No: Contact your next level of support.
6. If your system uses static IP addressing, add a system manually by performing the following steps:
   1. From the HMC, select Server Management.
   2. Select Add Managed System.
   3. Select the Add a managed system radio button.
   4. Enter the IP address/Hostname and password.

   Does the system appear under system management?

   • Yes: This ends the procedure.
   • No: Contact your next level of support.
