This setting may impact the performance of the primary system. This depends on this
setting and the amount of I/O activity. Using the default limits the impact on performance.

When you specify more than 64, the system starts copying in the first 64 pairs but does
not start the 65th pair until one of the pairs is synchronized, and so on.

host. The time of the Path Blockade Watch must be shortened than the setting time of MIH
timer in the host.
8. In the Path Blockade SIM Watch (sec.), enter the number of seconds the system will monitor
the SIMs that are reported when paths are blocked. The SIM watch value can be set from 2

the Path Blockade Watch.
