You can specify the maximum transfer rate for scheduled SnapMirror transfers using the kbs option in the snapmirror.conf file. However, you can change the maximum transfer rate for the current transfer by using the snapmirror throttle command. The change applies to the current transfer only, and the next scheduled transfer uses the maximum transfer rate that is specified in the snapmirror.conf file.
About this task
If you change the maximum transfer rate while the current transfer is active, the new maximum transfer rate takes effect within two minutes.
Note: If the SnapMirror relationships exist within the same system, you must set the snapmirror.volume.local_nwk_bypass.enable option to off to enable throttling of the SnapMirror transfers.
- To change the maximum transfer rate and apply it to the current transfer, enter the following command on either the source or destination system. snapmirror throttle n [system:]path
is the new maximum transfer rate in kilobytes per second. A value of zero (0
) disables throttling.
system is the destination system. Use this variable if you are executing the command on the source system.
path is the destination path. The path can be the /volume_name or /vol/volume_name/qtree_name.
