the maximum number. In an open system environment, when the memory heap size is Small or Medium,
the maximum number is the total number of LDEVs acquired from both the local and remote instances

acquired from the local and remote instances of Device Manager.

Note:
1. Use this formula to determine the number of LDEVs and confirm that the number is less than or
equal to the maximum:
(number-of-open-LDEVs * 2) + number-of-mainframe-LDEVs
Log data and number of copy pairs
The amount of log data depends on the number of copy pairs to be managed. You can change the
maximum number of log files and the maximum data size for each log file. For details, see
“logger.properties” on page 95.
