SET Utility
The SET utility allows you to change certain library configuration information without
performing reconfiguration on the library. The utility performs operations directly on the
control data set, without requiring the HSC to be active.
performing reconfiguration on the library. The utility performs operations directly on the
control data set, without requiring the HSC to be active.
In many cases, the SET function may run with an active HSC. In most such cases,
changes made are not effective until the HSC has been brought down and then reactivated.
Exceptions include:
changes made are not effective until the HSC has been brought down and then reactivated.
Exceptions include:
• SET FREEZE(ON|OFf), where frozen or unfrozen panels are recognized
immediately by all active HSCs.
• SET NEWHOST(newhost), where the new host will be ready to be brought online to
the HSC.
In other cases, the SET function requires that the HSC on a specific system be shut down,
or that all HSCs be shut down. This means that the heartbeat record indicates that the host
is not active, which can be achieved via the SCP STOP command. Table 14 on page 300
shows whether affected HSCs and all other HSCs can be active for each SET option.
Further information can be found in each individual option description.
