StorageTek Host Software Component 6 User Manual

1st ed., 6/30/04 - 312579601

The Volume Report utility executes in the SCP batch job environment in CMS, or in 
stand-alone mode in the POST/SAE environment. Stand-alone mode allows the 
administrator to locate backup tapes when the ACS service machine cannot be started due 
to the loss of a critical DASD data set. 

The control statement for each utility program consists of a command (indicating the 
utility function) followed by parameters, as applicable, in 80-character card-image 
records. For more information about this syntax, see Appendix A, “Macros, Control 
Statements, Utilities, and Commands Syntax Reference” on page 429. 

Utility syntax is illustrated using syntax flow diagrams. For a complete description of this 
syntax convention, refer to Appendix A, “Macros, Control Statements, Utilities, and 
Commands Syntax Reference” on page 429.

Most of the utility functions require the HSC (Host Software Component) to be 
operational. However, a few are either independent of the HSC or have special 
environmental requirements: 

• The Backup utility and the Journal Offload utility require the ACS service machine 

SCP to be available, but not the HSC. 

• The Restore utility likewise requires the SCP to be available and also requires the 

HSC to be non-operational. 

• The Activities Report utility, the Performance Log Reblocker utility, and the Volume 

Report utility run in the CMS environment and are independent of the HSC and the 
SCP. The Performance Log Reblocker can also be run in the MVS environment. 

Note: For systems running VM ESA Version 2 or higher, utilities that are run in 
CMS can run in XA or XC mode with SET 370ACCOM ON. For VM ESA below 
Version 2, utilities run in CMS must run in 370 mode.
