•
Maximum Initial Copy Activities: Number of concurrent initial copy and resync operations:
1 to 128 volumes. The default setting is 64 volumes. XP Continuous Access initial copy
activities can impact performance of the main subsystem, depending on amount of I/O
activity and number of pairs being registered at one time. The maximum initial copy
activities setting of 64 volumes limits the impact of initial copy activities on subsystem
performance. For example, if you set the maximum initial copy activities to 64 volumes
and add 65 XP Continuous Access pairs at one time, the MCU starts the first 64 pairs,
but does not start the 65th pair until one of the first four 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.): Time to monitor the blockade in paths on the MCU side. The
path blockade watch (sec.) setting specifies the time for monitoring blockade in the paths.
The path blockade watch value must be from 0 to 45 seconds. The default is 40 seconds.
•
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 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.
