Problem summary
**************************************************************** * USERS AFFECTED: All users of z/VM with the IBM 4768 CEX6S * * Crypto Card installed on an IBM z14 or z15 * * processor * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** When runnning z/VM 6.4 on an IBM z14 processor with one or more 4768 Crypto Express6 cards, the crypto resources may not be assigned for shared use during z/VM system IPL and cannot be used for sharing once the system is up and running. This problem may also occur when running on an IBM z15 processor and Crypto Express6 cards are installed with no Crypto Express7 cards. The QUERY CRYPTO command response shows each of the configured Crypto Express6 coprocessors and accelerators as available, free, and unspecified. This happens after applying APAR VM66248, new function support for the IBM 4769 Crypto Card CEX7S, when the CRYPTO APVIRTUAL statement in the SYSTEM CONFIGURATION file is not used to specify the AP and domain numbers of the Crypto Express6 resources which are intended to be used for sharing.
Problem conclusion
HCPKAP is changed to ensure that Crypto Express6 resources are found during z/VM system IPL when they haven't been specified on the CRYPTO APVIRTUAL statement in the SYSTEM CONFIGURATION file. The z/VM system will then operate as it did prior to this problem. If no CRYPTO APVIRTUAL statement is specified in the SYSTEM CONFIGURATION file, CP will choose the best crypto resources to be included in the shared pool. If the CRYPTO APVIRTUAL statement is specified in the SYSTEM CONFIGURATION file, CP will attempt to add the specified crypto resources to the shared pool.
