Connectivity and Call-Home Servers

Call-home servers transmit configuration and error diagnosis data to your service provider. Configuring one or more call-home servers enables you to report problems electronically to your service provider. This minimizes the response time and customer intervention required for problem determination.

If you have a single HMC, you must enable connectivity on this HMC.

If you have multiple HMCs, there are advantages in speed and reliability by configuring more than one call-home server. When more than one call-home server is configured and available, a brokering process automatically selects the first available console to transmit the problem request to your service provider. Any transmission failures will cause the problem request transmission to be automatically retried at remaining call-home server consoles.

Using the Call-Home Setup Wizard, you can configure the local HMC as a call-home server using the HMC Connectivity panel. You can also configure which other consoles can be used as call-home servers. By default, any call-home server that is on the same subnet as this HMC or manages the same system will be discovered. Using the Call-Home Server Consoles panel you can modify the list of call-home servers that can be used.
