show performance lun_priority

show performance lun_priority


The show performance lun_priority command is used to query the performance statistics of LUNs with a specific I/O priority. If you want to analyze the real-time performance statistics of LUNs with a specific I/O priority, run this command.


show performance lun_priority io_priority=? [ controller_id=? ] [ controller_id_list=? ]





controller_id=? Owning controller ID of LUNs.

To obtain the value, run the "show controller general" command.

io_priority=? I/O priority of LUNs.

The value can be:

  • "Low": The I/O priority is low.
  • "Middle": The I/O priority is medium.
  • "High": The I/O priority is high.
controller_id_list=? List of owning controller IDs of LUNs.

To obtain the value, run the "show controller general" command. If multiple owning controllers of LUNs need to be added, separate controller IDs with commas (,).



Usage Guidelines

  • After this command is executed, performance data categories are displayed. You can enter the serial number before a category and press "Enter" to view the category of data. You can enter multiple serial numbers and use commas (,) to separate them.
  • Performance statistics will be updated in real time.
  • Typing "q" on the command line interface (CLI) exits the performance statistics display.


Query the performance statistics of LUNs whose owning controller is "0A" and I/O priority is "Low".
