You can use the command-line interface (CLI)
to change the relationship bandwidth for a system.
About this task
The relationship bandwidth limit controls the maximum rate at which any one remote-copy
relationship can synchronize. The overall limit is controlled by the bandwidth
parameter of each system partnership. The default value for the relationship bandwidth limit is 25
megabytes per second (MBps), but you can change this value by following these steps:
Procedure
-
Issue the lssystem command to list the current relationship bandwidth limit
of the system.
For example:
lssystem system_id_or_system_name
Where
system_id_or_system_name is the ID or name of the system.
- For future reference, record the current relationship bandwidth
limit that is displayed.
For example: relationship_bandwidth_limit
25
- To change the relationship bandwidth limit of the system,
issue the following command:
chsystem -relationshipbandwidthlimit
system_relationship_bandwidth_limit
Where system_relationship_bandwidth_limit is the new limit for the system. If
the system is in a remote partnership with another system, then the bandwidth setting must be the
same between both systems in the partnership. Issue the command on both systems in the partnership.
Issue the command on both systems in a relationship.
