defaultHostType
The default host type of any unconfigured HBA host
port to which the controllers are connected. To generate

Host types are identified by a name or a numerical
index. Enclose the host type name in double quotation
marks (“ ”). Do not enclose the host type numerical
identifier in double quotation marks.
