You can specify whether or not the library control data set is updated as a result of audit, or
if only the discrepancy listing is produced by the parameters chosen.
• If the APPly(YES) is specified, the library control data set is updated to reflect all
observed contents in cell storage. A discrepancy listing is also produced. Duplicate
VOLSERs and cartridges with unreadable or illegal external labels are ejected from
the LSM. Cartridges that are not recorded in the CDS that have external media labels
that are unreadable are also ejected.
Note: The discrepancy list identifies differences between the CDS and the physical
inventory. APPly(YES) is the default setting.
• If APPly(NO) is specified, duplicate VOLSERs and cartridges with
unreadable/illegal external labels are not ejected, the library control data set is not
updated, and a discrepancy listing is produced.
Media Type Mismatch Conditions
The Audit utility can address a mismatch condition if the LMU reports a different media
type than the CDS contains. In this case, an unreadable external media label exists, and the
vision system cannot determine the media type.
Note: CDS media information is updated when the volume external label is read by the
robotic vision system and is transmitted back to the HSC through the LMU.
It is recommended that users provide an external media label for all cartridges. An
SL8500 library will not enter a non-labeled cartridge.
Depending on the parameters input by the user, the following actions occur:
1. If APPLY(YES) is specified (or defaulted to):
• If the LMU and a VOLATTR are mismatched, the VOLATTR is incorrect, and
the HSC issues a warning message.
• If the media values for the LMU and the VAR do not agree, the HSC issues a
warning message, and the CDS is updated to reflect the value reported by the
LMU.
• If the media value is unreadable by the LMU (for a cartridge recorded in the
CDS), the HSC issues a warning message, and the CDS is updated to indicate
that the media value of this volume is unreadable.
• If the media value is unreadable by the LMU (for a cartridge not recorded in the
CDS), the HSC issues a warning message, and the volume is ejected.
2. If APPLY(NO) is specified:
• If the LMU and a VOLATTR are mismatched, the VOLATTR is incorrect, and
the HSC issues a warning message.
• If the media values for the LMU and the VAR do not agree, the HSC issues a
warning message.
