Hello, everyone!

Disks are managed using the EVS during the entire process from disk creation to release, do you know how many states does an EVS disk has?

All I know is creating, deleting, in use...

I am studying Huawei HCS products. I want a complete EVS disk status table. Who can provide an EVS disk status table?

Thanks in advance!
