StorageTek 6 manual User Control of HSC Functions, Macros, Utilities, PARMLIB Control Statements

User Control of HSC Functions

Various controls are in place in the HSC software to permit you to select how the HSC functions. Macros, Utilities, and PARMLIB control statements are normally used by the systems programmer to tune and customize the system. Commands are normally invoked by a systems operator in the performance of daily operations tasks. A description of the function of each of these available controls follows.

Macros

Macros are provided primarily to help you set up the library software configuration or library generation (LIBGEN).Refer to Chapter 6, ‘‘Creating the Library Configuration File (LIBGEN)’’ in the HSC Installation Guide for detailed information about the LIBGEN macros and how they are used to configure a library.

Utilities

Utilities are provided to allow you to manage library resources. The utilities enable you to dynamically:

•perform maintenance on control data sets

•control cartridge and scratch volume functions

•produce performance, activity, and inventory reports relating to a library.

Refer to Chapter 4, “Utility Functions” on page 169 for detailed information about the HSC utilities and how they are used to manage library resources.

PARMLIB Control Statements

PARMLIB control statements are provided to enable you to set initial values for system functions at HSC initialization. The PARMLIB control statements define HSC functions such as:

•host-to-host communications parameters

•definition of scratch subpools

Note: Refer to “Options Offered by PARMLIB Control Statements” on page 84 for an important warning about defining scratch subpools.

•data set definitions including: the primary, secondary, standby control data sets, and journals

•extended parameter list for startup.

Refer to “PARMLIB Control Statements” on page 83 for detailed information about the control statements and usage.
