Coexistence with Previous Releases

This section describes ELS 7.3 software coexistence and compatibility.

Note:

ELS 7.3 is not compatible with any releases prior to 7.1 with the exception of HSC/VM 6.2.

SMC 7.3 Coexistence

SMC 7.3 is compatible with the following software releases:

  • HSC/VTCS 7.3 on same host
  • HSC/VTCS 7.1, 7.2 and 7.3 on different host
  • MVS/CSC 7.3 only

HSC/VTCS 7.3 Coexistence

HSC/VTCS 7.3 is compatible with the following software releases:

  • SMC 7.3 on same host
  • SMC 7.1, 7.2 and 7.3 on different host
  • LibraryStation 7.3 only
  • ExPR 6.1 only

Compatibility PTFs

With proper compatibility PTFs, ELS 7.3 can share a CDS with ELS 7.1 and above and with HSC/VM 6.2. ELS 7.1 and 7.2 support a VTCS CDS level of H or below. For 32GB VTV support an I level CDS is required.

Before attempting to start ELS 7.3, ensure that the following compatibility PTFs are installed on the down level releases that share the CDS:

Table 1-2 Compatibility PTFs

Product FMID Compatibility PTF
HSC (VM) 6.2 (SMS6200) L1H188F
ELS 7.1 (SSEA710) L1H185B
ELS 7.2 (SSEA720) L1H185C

Note:

  • All ELS software running on the same host must be at the same release level.
  • SMC 7.3 is completely compatible with HSC 7.1 or 7.2 (with compatibility PTFs listed below) running on a different host.
  • SMC 7.1 and 7.2 are completely compatible with HSC 7.3 running on a different host.

In addition, it is strongly recommended that you obtain the latest service (including HOLDATA) for the down-level hosts systems.
