The Scheduled Operation task with the new backup options for the SEs is changed, as shown in Figure 11-7. 

## 11.2.7 SE driver support with the HMC driver 

<img src='content_image/977762.jpg'>

HMC legacy systems support (Statement of Direction $^{a}$): IBM z14 is planned to be the last release that will allow HMC support across the prior four generations of server (N through N-4). 

Future HMC releases are intended to be tested for support of the previous two generations (N through N-2). For example, the next HMC release would support the zNext generation, plus z14 generation and z13/z13s generation. 

This change will improve the number and extent of new features and functions that can be pre-tested and maintained in a given release with IBM’ s continued high-reliability qualification procedures.

The driver of the HMC and SE is equivalent to a specific HMC and SE version, as shown in the following examples: 

GLYPH<SM590000> Driver 79 is equivalent to Version 2.10.2 

GLYPH<SM590000> Driver 86 is equivalent to Version 2.11.0 

GLYPH<SM590000> Driver 93 is equivalent to Version 2.11.1 

GLYPH<SM590000> Driver 15 is equivalent to Version 2.12.1 

GLYPH<SM590000> Driver 22 is equivalent to Version 2.13.0 

GLYPH<SM590000> Driver 27 is equivalent to Version 2.13.1 

GLYPH<SM590000> Driver 32 is equivalent to Version 2.14.0 

GLYPH<SM590000> Driver 36 is equivalent to Version 2.14.1 

An HMC with Version 2.14.1 or Version 2.14.0 can support different IBM Z types. Some functions that are available on Version 2.14.1 and later are supported only when the HMC is connected to an IBM Z server with Version 2.14.1.
