StorageTek Host Software Component 6 User Manual

1st ed., 6/30/04 - 312579601

The HSC contains utility functions that provide you with ways to manage library 
resources. Primary utility functions include:

• library CDS maintenance 
• control of library cartridges 
• control of scratch volumes 
• preparation of reports covering library activity. 

In addition, utilities contain the following attributes: 

• Most are submitted to the SCP for execution, but some require or allow special 

environments. 

• Utilities submitted as batch jobs to the SCP require the use of special SCP JCL 

(SLKJCL) statements. 

• Specific utility functions are requested by special utility control statements which 

define the function and supply all required parameters; these are distinct from JCL 
statements.
