Use this Creating a Metro or Global Mirror Cluster Partnership
panel in the SAN Volume Controller Console to
create a Metro
Mirror or Global Mirror cluster
partnership.
Introduction
A Metro
Mirror or Global Mirror partnership
defines the relationship between a local cluster and a remote cluster.
To create a fully functional partnership, you must also establish
a one-way partnership on the remote cluster to the local cluster.
Fields
You
can update the following fields:
- Remote Cluster
- Select the remote cluster to use to establish a one-way partnership
with the local cluster.
- Bandwidth
- Enter the rate at which the background copy from the local to
the remote cluster is performed. You can set this attribute differently
for the path from cluster A to cluster B and for the path from cluster
B to cluster A.
- Link Tolerance
- Enter the length of time that the primary response time must remain
impacted before relationships are suspended. You can specify a value
from 0 to 86400 seconds in steps of 10. A value of zero disables this
feature. The default value is 300 seconds.
- Inter-Cluster Delay Simulation (ms)
- Enter the amount of time to delay I/O writes to the intercluster
secondary VDisk. You can type a value from 0 to 100 milliseconds
(ms). A value of zero disables this feature. The default value is
zero.
- Intra-Cluster Delay Simulation (ms)
- Enter the amount of time to delay I/O writes to the intracluster
secondary VDisk. You can type a value from 0 to 100 milliseconds
(ms). A value of zero disables this feature. The default value is
zero.
Actions
The
following actions are available:
- OK
- Click this button to create a cluster partnership.
- Cancel
- Click this button to exit the panel without creating a cluster
partnership.
