Reconfiguration Utility

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.

Reasons for Running the Reconfiguration Utility

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.
