Target rate limiting settings
Target rate limiting throttles the Fibre Channel Protocol (FCP) read traffic rate to slow-draining
targets to reduce or eliminate network congestion and alleviate I/O slowdowns to faster targets.
Use the following BCU commands to determine current status and configuration for target rate
limiting settings:
Determining target rate limiting settings through BCU
Use the following BCU commands to determine current status and configuration for target rate
limiting settings:
•
Use the following BCU command to determine target rate limiting speed and enabled status.
ratelim --query <port-id>
where:
port_id
ID of the port for which you want to display target rate limiting settings. This
could be the PWWN, port hardware path, or user-specified port name. This
could also be the adapter-index/port-index. For example, to specify adapter 1,
port 1 you would use 1/1 as the port identification.
•
Use the following BCU command to display target rate limiting enabled status and default
speed.
port --query <port-id>
where:
port_id
ID of the port for which you want to display port information.
•
Use the following command to determine operating speed of the remote port and target rate
limiting enforcement.
rport --query <port_id> <rpwwn>
where:
port_id
Specifies the ID of the port for which you want to query attributes of a remote
port.
rpwwn
Remote PWWN. You can obtain the RPWWN from the BCU rport --list
<port_id> command.
