Displays information about the status of the HMC connection to the service processors on the managed system.
You can see the state of the connection from the HMC to the primary and secondary service processors. The HMC will operate normally with a connection to only the primary service processor. However, for code update operations and some concurrent maintenance operations on the managed system, the HMC needs connections to both the primary and secondary service processors. If no secondary service processor is installed, only one connection to the primary service processor is required.
If service processor failover occurs and the HMC does not have connections to both the primary and secondary service processors, then the HMC will not be able to establish a connection to the managed system after failover has completed.
The following columns are shown:
- IP Address
- The IP address of the service processor is displayed. The IP address is a unique, 32-bit integer. The address is expressed in the form xxx.xxx.xxx.xxx where each field is the decimal representation of one byte (8 bits) of the address. For example, the IP address whose hexadecimal representation is X'82638001' is expressed as 130.99.128.1. The IP address is always specified in conjunction with its subnet mask. The subnet mask specifies which bits of the IP address belong to the network portion of the IP address and which bits of the IP address belong to the host portion of the IP address.
- Service Processor Role
- This column indicates whether the connection is to the primary service processor or the secondary service processor.
- Connection State
- The state of the HMC connection is displayed. If the state is not Connected, the error code that indicates the reason for the connection failure is shown in the Connection Error Code column.
- Connection Error Code
- The error code that indicates the reason for the connection failure is displayed. This column is blank when the value in the Connection State column is Connected.
