zIIP usage:  zIIPs can be defined to General mode or z/VM mode image, as listed in Table 3-6 on page 135. However, zIIPs are used only by z/OS. Other operating systems cannot use zIIPs, even if they are defined to the LPAR. z/VM V6R4 and later support real and virtual zIIPs to guest z/OS systems. 

GLYPH<SM590000> General mode is also used to run the z/TPF operating system on dedicated or shared CPs 

GLYPH<SM590000> CF mode, by loading the CFCC code into the LPAR that is defined as one of the following types: 

– Dedicated or shared CPs 

– Dedicated or shared ICFs 

GLYPH<SM590000> Linux only mode to run the following systems: 

– A Linux on Z operating system, on either of the following types: 

GLYPH<129> Dedicated or shared IFLs 

GLYPH<129> Dedicated or shared CPs 

– A z/VM operating system, on either of the following types: 

GLYPH<129> Dedicated or shared IFLs 

GLYPH<129> Dedicated or shared CPs 

GLYPH<SM590000> z/VM mode to run z/VM on dedicated or shared CPs or IFLs, plus zIIPs and ICFs 

GLYPH<SM590000> Secure Service Container (SSC) mode LPAR can run on dedicated or shared: 

–C P s 

–I F L s 

All LPAR modes, required characterized PUs, operating systems, and the PU characterizations that can be configured to an LPAR image are listed in Table 3-7. The available combinations of dedicated (DED) and shared (SHR) processors are also included. For all combinations, an LPAR also can include reserved processors that are defined, which allows for nondisruptive LPAR upgrades.
