Copy Threshold option

activity on the storage system becomes heavy. The use of this option is not recommended for hosts
that frequently update volumes which are likely to be migrated because of the increased possibility
of failure during migration.
For information about setting the Copy Threshold option, call the HP Technical Support.
The Copy Threshold option also stops migration operations associated with the following products:
•
Business Copy
•
Business Copy Z
