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).
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:
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 an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.

I was trying to change a group cap and was on an LPAR that was not in the group. Instead of getting a bad data return code or something meaningful I got:
REXXHostRc = 0 rc = 101
DiagArea.Diag_Index = 0
DiagArea.Diag_Key = 146
DiagArea.Diag_Actual = 0
DiagArea.Diag_Expected = 0
DiagArea.Diag_CommErr = 21
DiagArea.Diag_Text =
which is a Communication Error and typically means that the SE may be busy.
This misleading error caused us to waste a lot of time. We eventually realized that there was no group on that LPAR, so the cap could not be changed. But the error did not reflect that.
Support told me that they were looking at the codes and it does not look like the hardware has a
specific code for an Image not being defined to a group so it is defaulting to the SE Busy code. They said the error does not even relate to the issue at hand and suggested opening a RFE against the API for more specific Return
Codes for Service Element Errors.
Thanks

Originally SNMP/BCPiiV1 exposed group capping via the Image (Logical Partition) object. This is the path the customer was using when trying to change a group capping attribute. In addition, starting with z14, the SNMP/BCPiiV1 interface also exposes these attributes via the LPAR group object. The latter implementation is more correct since these attributes are really part of the group and not part of the Image. This is also consistent with the new BCPiiV2 interface. The customer should use this path for the automation to avoid getting this cryptic failure since it is more correct and how things will be done in the long run with BCPiiV2.
Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - Z and LinuxONE Systems Hardware
Product - Z and LinuxONE Systems Hardware
Component - HMC/Support Element (SE)
Operating system - IBM z/OS
Source - None
For recording keeping, the previous attributes were:
Brand - Servers and Systems Software
Product family - z Systems Software
Product - z/OS
Component - BCP_BCPii
Operating system - IBM z/OS
Source - None
