IBM Z Hardware and Operating Systems Ideas Portal


This is the public portal for all IBM Z Hardware and Operating System related offerings. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas
  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Add CALL-HOME function when "Report Loss of Communication" detected as HMC options of z Systems.

In unattended service sites, if the HMC-SE network is disconnected for some failures, no one can find it because there is only H/W messages of "Report Loss of Communication" on HMCs, and there is no option for call-home of it. Therefore, SE failures might be overlooked. If CEC itself crashed and both SEs are unavailable, the customer could not find the failure for a long time since call-home function will not be invoked. This is big impact to the customer.

    Hi Kiyoshi,

    Brian, Keri and HMC/SE team reviewed this zRFE and came up with three existing approaches for BTMU to detect when there is true loss of communication between the HMC and SE:
    The customer can use the HMC Event Monitor task to create a monitor for the specific Hardware Message describing this true loss of communication.
    If this event is detected, then an email will be sent to one or more email addresses at an SMTP server.
    The customer can configure the email/SMTP server to further send out a text message or other notification to a person.
    The customer can use automation to get an asynchronous event for the specific HW message for this true loss of communication.
    Both SNMP and WebServices APIs provide this support.
    Finally, an HMC user can manually examine hardware messages as they come in.
    While the system may run unattended, I assume the customer is monitoring the system/HMC remotely via a web browser connection.
    Otherwise, they should be using one of the above techniques, not just for this HMC/SE loss of communication, but other HW messages.

    I think these are very good options so I'm asking you to assess them. As these options are available today you could go ahead and implement at BTMU right away.

    Let me know if you have any further questions to either of the options or have a need to directly discuss with the SE/HMC development team.
