Description Starting with ICSF Cryptography FMID HCR77A1, only z890 or later servers are supported. Also, starting with z/OS V2R1, only z9 or later servers are supported. The migration check is available for HCR7770, HCR7780, HCR7790, and HCR77A0 through APAR OA42011.
| Element or feature: | Cryptographic Services |
| When change was introduced: | Cryptographic Support for z/OS V1R13 – z/OS V2R1 web deliverable (FMID HCR77A1), which installs on z/OS V1R12, z/OS V1R13 or z/OS V2R1. |
| Applies to migration from: | z/OS V1R13 and z/OS V1R12. |
| Timing: | Before installing z/OS V2R1. |
| Is the migration action required? | Yes, if you have installed the Cryptographic Support for z/OS V1R13 – z/OS V2R1 web deliverable (FMID HCR77A1) to determine which servers can support HCR77A1. As of HCR77A1, only z890 or later servers are supported. |
| Target system hardware requirements: | z890 or later. |
| Target system software requirements: | None. |
| Other system (coexistence or fallback) requirements: | None. |
| Restrictions: | None. |
| System impacts: | If running on z/OS R13 or z/OS 2.1, and attempt to start HCR77A1 on a z800 or z900, you will receive the following message ICSFM010E ICSF TERMINATING. PROCESSOR IS UNSUPPORTED, and ICSF will not start. |
| Related IBM Health Checker for z/OS check: | You can use the IBM Health Checker check ICSFMIG77A1_UNSUPPORTED_HW to determine if your current server can support HCR77A1. The migration check is available for HCR7770, HCR7780. HCR7790, and HCR77A0 through APAR OA42011. |
Steps to take: Ensure that if you are planning to run HCR77A1, that it will be on a supported server. Run the migration check ICSFMIG77A1_UNSUPPORTED_HW to determine if HCR77A1 can start on your current server.
