Displaying/Setting Service Level
An HSC operator command, SRVlev, sets a different service level. Refer to information
presented on the Display command in Chapter 2, ‘‘Commands, Control Statements, and
Utilities’’ in the
HSC Operator’s Guide for information on how to display the current HSC
service level.
Starting the HSC Subsystem at Base Service Level
If the HSC and the library are new to your data center, you may want to install the HSC
software and start the subsystem at the base service level before your library hardware is
physically installed. Starting the HSC at the base service level allows you to perform
many of the preliminary tasks involved in configuring your library and performing
preliminary tests on basic operation.
Normally the HSC subsystem is initialized to the full service level when started. The HSC
can be started at the base service level only by specifying the BASE parameter in the
startup SLKJCL file. Then, the Service Level (SRVlev) command can be used to bring the
HSC to full service level whenever you are ready.
Refer to “Initializing the HSC to the Base Service Level” on page 129 for information
about setting the service level at HSC initialization.
