Copy Threshold option

The Copy Threshold option can be configured to temporarily stop Auto LUN operations when
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 HP Technical Support.
The Copy Threshold option also stops migration operations associated with the following products:
Business Copy
Business Copy Z
Compatible FlashCopy
