Description
A recovery policy
determines whether the
system automatically
synchronizes data after a
HyperMetro fault is
rectified.
l Automatic: The system
automatically
synchronizes data.
l Manual: The
synchronization
operation must be
performed manually.
Speed of data
synchronization between the
primary resource and
secondary resource. Possible
values are Low, Medium,
High, and Highest.
Time when data
synchronization for a
HyperMetro starts.
Time when data
synchronization for a
HyperMetro ends.
After the Isolation Switch
is turned on, the system will
suspend the HyperMetro
pair when the difference
between the write I/O
latency of the two storage
arrays is greater than the
isolation switch. The storage
array with the longer write
I/O latency will stop
providing services.
