Terms:
Inconsistent Data in the volume is inconsistent because it is being
copied.
Suspect The primary volume data and secondary volume data
are not consistent (the same).
Must be analyzed It cannot be determined from the status of the
secondary volume whether data is consistent. It is “OK”
if the status of the primary volume is PAIR. It is
“suspect” if the status is PSUS or PSUE.
Needs to be confirmed
It is necessary to manually check the volume.
When the S-VOL Data Consistency function is used, paircurchk sets
either of the following returned values in
exit(), which allows users to
check the execution results with a user program.
normal termination
0 (OK. Data is consistent.)
abnormal termination
Other than 0. (For the error cause and details, see the
execution logs.)
