The Path Blockade Watch (sec.) setting specifies the time for monitoring
blockade in the paths. The path blockade watch value must be from 2 to 45
seconds. The default setting is 40 seconds.
Note: If you create a pair with the synchronous mode, and if the status of all
paths becomes "Monitoring" because of a path error, MIH may occur in the
host. The time of the Path Blockade Watch must be shortened than the
setting time of MIH timer in the host.
The Path Blockade SIM Watch (sec.) setting specifies the time for
monitoring SIMs that are reported when paths are blocked. The path blockade
SIM watch value must be from 2 to 100 seconds. The default setting is 70
seconds. The value of the Path Blockade SIM Watch cannot be smaller than
the value of the Path Blockade Watch.
The Services SIM of Remote Copy setting displays the status of whether the
service SIM in storage system is reported to the host or not.
