SYSTEM
DEST
MESSAGE
Represents the NODEID value of the system that currently owns the volume.
This field will be blank for volumes in scratch status.
Indicates the system which will receive the synchronization information for the
volume. SYS1 indicates the system represented by the data sets CAT1IN and
CAT1OUT, which is displayed on the left side of the report. SYS2 indicates the
other system. BOTH indicates that both systems are to receive information
about this volume. NONE indicates that a critical data error was detected for
the volume. The MESSAGE field contains more information.
Contains additional information for determining why a discrepancy occurred. If
this field is blank, a discrepancy was found in the information stored for the
volume (that is, data set name, creation date, and so on). The synchronization
utility assumes that the volume with the most current creation date and time
is accurate and sends this information to the other system.
Depending on the type of discrepancy that occurs, you can receive any of the
following messages:
CREATION DATE/TIME DOES NOT MATCH
Indicates that the creation date and time are not the same on both systems.
The conflict is resolved automatically by selecting the volume with the most
recent date and time.
DATA SET NAMES DO NOT MATCH
Indicates that the data set names are not the same on both systems. The
conflict is resolved automatically by selecting the volume with the most recent
creation date and time. If both volumes have the same date and time, the
owning system is assumed to have the correct data set name and will be used
to update the other system.
EACH SYSTEM CLAIMS OWNERSHIP
Indicates conflicting ownership of the volume. Each system thinks the tape is
under its control. The conflict is resolved automatically based upon the most
recent creation date and time.
NEITHER SYSTEM CLAIMS OWNERSHIP
Indicates that each system thinks the other system is controlling the tape. The
conflict is resolved automatically by scratching the volume on both systems.
The information from the record with the most recent creation date and time is
used to update the volumes on each system.
