7. Delete the temporary PrimeSync management group.

8. Use the initial snapshot that you used for the temporary PrimeSync management group copy,

to create the second Remote Copy or the schedule to create remote snapshots of the volume.

You are now setting up the Remote Copy that goes from primary site A directly to remote site

B which maintains that relationship going forward.

PrimeSync ensures that the proper relationship is established between the original primary volume

and the remote site. Subsequent remote snapshots from the primary site to the remote site are

incremental.

Viewing a list of remote snapshots

View a list of remote snapshots associated with management groups, clusters, volumes, or snapshots.

1. In the navigation window, select a cluster to view its list of remote snapshots.

2. Click the Remote Snapshot.

The report in the Remote Snapshot tab lists management groups and all the snapshots. The

other columns show status information about the remote snapshots. For more information, see

“Monitoring remote snapshots” (page 18).

Setting the remote bandwidth

The remote bandwidth sets the maximum rate for data transfer between management groups. The

copy rate is equal to, or less than, the rate set. The factory setting is a Custom setting of 4.

To control the maximum rate of data transfer to a remote snapshot, set the remote bandwidth on

the management group that contains the remote snapshot which is the remote management group.

When setting the remote bandwidth, you can choose from a list of common network types, or

calculate a custom rate, based on your particular requirements.

Selecting remote bandwidth rate

You may either select a preset speed from a list of standard network types or calculate a custom

speed based on your specific requirements. Remember that the speed is the maximum rate at which

data copies.

• Defaults setting—When setting remote bandwidth, selecting Defaults allows you to choose

from a list of common network types, listed in Table 5 (page 16).
