You can change the current setting
for bandwidth, which is also known as background copy. The partnership
bandwidth controls the rate at which data is sent from the local cluster
to the remote cluster. The partnership bandwidth can be changed to
help manage the use of inter-cluster links. It is measured in megabytes
per second (MBps).
This task assumes that you have already launched the SAN Volume Controller Console.
To change the bandwidth setting for a selected Metro or
Global Mirror partnership, complete the following steps:
- In the portfolio, click . The
Viewing Metro & Global Mirror Cluster Partnership panel displays.
- From the partnership list, select the cluster partnership
that you want to modify. Select Modify a Partnership Bandwidth from
the task list. Click Go. The Modifying Metro &
Global Mirror Bandwidth panel is displayed.
- Type the new rate for the background copy.
Note: You
can set the bandwidth attribute for the path from cluster A to cluster
B to a different setting from the setting that is used for the path
from cluster B to cluster A.
- Click OK.
