Reference: Unit numbers are numbers assigned to each PT when multiple PTs are con- nected to one host, so that the host can identify the individual PTs. The units num- bers that can be set differ according to the host model, as follows.

SC200HE(-ZE):

Unit numbers 0 to 3 (maximum of 4 PTs per host port)

SC200HG(-ZE), C200HX(-ZE):

Unit numbers 0 to 7 (maximum of 8 PTs per host port)

When making the settings, make sure there is no duplication of unit numbers among PTs.
