System option modes
To provide greater flexibility and enable the HUS VM to be tailored to unique
customer operating requirements, additional operational parameters, or
system option modes, are available. At installation, the modes are set to
their default values, as shown in the following table. Be sure to discuss
these settings with your Hitachi Data Systems team if you think changes
should be made. The system option modes can only be changed by a Hitachi
Data Systems representative.
The following tables provide information about system option modes and
and SVP operations:
• Table B-1: System option modes on page B-2 lists the public system
option mode information for HUS VM. These can be used as needed.
