The Reconfiguration utility is used as part of a four-stage process to create a new copy of 
the control data set when library hardware configurations change, such as the addition of 
drives or LSMs, but when information regarding the location of cartridges in the library 
must be retained from the original control data set. 

Note: This utility requires a 2.1-level CDS.

The four stages include: 

• performing a LIBGEN to create the new hardware configuration 

• executing the SLICREAT procedure to format the new CDS that will hold the 

information transferred from the old CDS during the execution of the 
Reconfiguration utility 

• executing the Reconfiguration utility to transfer current cartridge information from 

the old CDS to the new CDS taking into account the hardware configuration changes 
made 

• possibly executing a partial audit that may be necessary to make final corrections to 

the CDS contents for panels that may have changed as a result of hardware 
configurations, such as the addition of drive panels. 

The Reconfiguration utility executes as an SCP job with the HSC at the base service level 
and runs as a special invocation of the HSC. The Reconfiguration utility uses as input the 
CDSDEF control statement (points to the old CDS) as its information source and the 
RECDEF control statement (points to the newly formatted CDS) as the target where the 
updated information is stored. 

The Reconfiguration utility minimizes the amount of time that the library is unavailable 
for your use due to library modifications. Some typical examples of library modifications 
are:

• an LSM panel is reconfigured (possibly by adding a drive panel to the LSM) 

• an LSM is added to the existing configuration. Usually, this causes a change to the 

configuration of some of the existing LSMs since PTP panels replace panels that are 
currently full wall panels. 

• an ACS is added to the library 

• an LSM, or an entire ACS, is removed from the library.
