VSM ALLOWUSERKEYCSA(NO) only prevents obtaining user key CSA. It does not prevent creating a user key CADS, or using CHANGKEY to change the key of subpool 247 or 248 (DREF SQA) storage to user key. The health check and the new SMF 30 field report all three of those types of security issues, and all three will be disallowed in the next release after z/OS 2.3.
So I would think that you would want to keep the health check enabled. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp.
