Use this option to change the default host type at the storage subsystem level.
The host type defines how the controllers in the storage subsystem work with the host's operating system when logical drives are accessed. The only time you will use this option is if you need to change how the storage subsystem operates relative to the hosts that are connected to it. Generally, you will use this option only if all hosts connected to the storage subsystem have the same operating system (homogeneous host environment).
If you are in an environment where there are attached hosts with different operating systems (hetergeneous host environment), you will define the individual host types as part of creating storage partitions. Changing the default host type with Storage Partitioning enabled will only affect any hosts you do not define in the Mappings View and any logical drives mapped in the default group.
The host type would need to be changed if:
Important: If an incorrect host type is selected, existing logical drives should still be visible, but redundancy through the multi-path driver (if installed) could fail.
