Changing the Default Host Type of a Storage Subsystem

Use the Change Default Host Type option to change the default at the level.

The host type defines how the in the storage subsystem work with the operating system when they are accessed. The only time that 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 of the hosts that are connected to the storage subsystem have the same operating system (homogeneous host environment).

If you are in an environment in which there are attached hosts with different operating systems ( environment), you will define the individual host types as part of creating . Changing the default host type with Storage Partitioning enabled affects only hosts that you do not define in the Mappings tab and any logical drives that are mapped in the . Before setting up multiple hosts for a heterogeneous environment, read the information in the Restricted Mappings online help topic.

You must change the host type if one of these conditions exists:


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.

  1. From the Subsystem Management Window, select the storage subsystem, and select Storage Subsystem >> Change >> Default Host Type .
  2. In the New Host Type list, select the host type. The list shows all of the defined host types.
  3. Click OK.
