how to clean/reset IO class?

[zyb521]

Question

I have load a ioclass-config.csv，but i don't find the way to clean/reset it in the Admin Guide.
Is there any other reference document?

thanks all.

# cat ioclass-config.csv
IO class id,IO class name,Eviction priority,Allocation
0,unclassified,22,0
1,request_size:le:131072,1,1

# casadm -C -L -i 1
╔═════════════╤════════════════════════╤═══════════════════╤════════════╗
║ IO class id │     IO class name      │ Eviction priority │ Allocation ║
╠═════════════╪════════════════════════╪═══════════════════╪════════════╣
║           0 │ unclassified           │                22 │       0.00 ║
║           1 │ request_size:le:131072 │                 1 │       1.00 ║
╚═════════════╧════════════════════════╧═══════════════════╧════════════╝

now i delete the ”1“ class，then reload the ioclass-config.csv

casadm -C -L -i 1
╔═════════════╤═══════════════╤═══════════════════╤════════════╗
║ IO class id │ IO class name │ Eviction priority │ Allocation ║
╠═════════════╪═══════════════╪═══════════════════╪════════════╣
║           0 │ unclassified  │                22 │       0.00 ║
╚═════════════╧═══════════════╧═══════════════════╧════════════╝

So io class not take effect at this time?
