How the SET Utility Functions
One of the facilities provided by the SET utility is to change the RESERVE QNAME that
was defined during LIBGEN and stored in the CDS. The RESERVE QNAME is used by
the HSC and utilities running on each host to ensure that access to the CDS is serialized.
The SET utility and HSC use an additional StorageTek-defined RESERVE QNAME to
maintain serialization while the customer-defined RESERVE QNAME is being changed.

the HSC and utilities running on each host to ensure that access to the CDS is serialized.
The SET utility and HSC use an additional StorageTek-defined RESERVE QNAME to
maintain serialization while the customer-defined RESERVE QNAME is being changed.
The SET utility issues two RESERVEs against the CDS prior to an update, consisting of:
• A RESERVE with the StorageTek-defined QNAME ‘‘STKENQNM’’
• A RESERVE using the existing customer-defined QNAME (or the default value of
‘‘STKALSQN’’).
