activities setting of 64 volumes allows you to limit the impact of initial copy activities on subsystem

performance. For example, if you set the maximum initial copy activities to 64 volumes and then

add 65 TrueCopy z/OS pairs at the same time, the MCU starts the first 64 pairs and will not start

the 65th pair until one of the first 64 pairs is synchronized (Duplex status). When you change the

maximum initial copy activities setting, the new setting applies to pairs created after the setting was

changed, not to existing pairs.

Path Blockade Watch

(sec.) specifies the time for monitoring blockade in the paths. The path

blockade watch value must be from 0 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 Patch Blockade

Watch must be shorter than the setting time of MIH timer in the host.

Path Blockade SIM Watch

(sec.) specifies the time for monitoring SIMS that are reported when paths

are blocked. The path blockade SIM watch value must be from 1 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.
