change remote_device link

change remote_device link


The "change remote_device link" command is used to modify the attributes of a link to a remote device.


change remote_device link link_type=? link_id=? { bandwidth_limit_enabled=? [ bandwidth=? ] | bandwidth_utilization_rate=? | ip=? | recovery_policy=? } *





link_type=? Type of a link.

The value can be:

  • "FC": The remote device and the local device connect to each other through Fibre Channel links.
  • "iSCSI": The remote device and the local device connect to each other through iSCSI links.
link_id=? ID of a link.

To obtain the value, run "show remote_device link".

bandwidth_limit_enabled=? Whether or not to enable bandwidth limitation.

The value can be:

  • "yes": Bandwidth limitation will be enabled.
  • "no": Bandwidth limitation will be disabled.
bandwidth=? Bandwidth of a link. This parameter is valid only when "bandwidth_limit_enabled=?" is set to "yes".

The value is an integer followed by a unit. The unit can be G, M or K, which respectively correspond to Gbps, Mbps or Kbps. For example, the value can be "500M".

bandwidth_utilization_rate=? A bandwidth utilization rate.

The value ranges from 1 to 100, expressed in percentage.

The default value is "75".

ip=? IP address of a remote device. This parameter is valid only when "link_type=?" is set to "iSCSI".


recovery_policy=? A link recovery policy. This parameter is valid only when "link_type=?" is set to "iSCSI".

The value can be:

  • "automatic": indicates automatic recovery.
  • "manual": indicates manual recovery.
The default value is "automatic".



Usage Guidelines

  • A link bandwidth too large will invade the bandwidth resources for other services, whereas a link bandwidth too small will cause service instability or timeout.2:Before running this command, ensure that the set bandwidth is appropriate for onsite requirements.


To modify the attributes of Fibre Channel link "4", where bandwidth limitation will be enabled, the bandwidth threshold is "400M", and the bandwidth utilization rate is "80%", run the following command:

admin:/>change remote_device link link_type=FC link_id=4 bandwidth_limit_enabled=yes bandwidth=400M bandwidth_utilization_rate=80
WARNING: You are going to set the bandwidth of the link (source-target information). A link bandwidth above the threshold affects the performance of other services, and a link bandwidth below the threshold affects the performance of the current service.
Suggestion: Before you perform this operation, determine the link bandwidth that is actually required and the bandwidth that can be allocated from the physical link to the current connection.
Have you read warning message carefully?(y/n)y
Are you sure you really want to perform the operation?(y/n)y
Command executed successfully.
