I am not sure what you mean by the question. Are you looking for a way to find out how much of a lun a host is using? If so, then there is no way from the CLARiiON side to know how much of a lun's total space is consumed by the host. The CLARiiON has no view into the data, so tracking space used is not possible.  -Ryan
Is there a way to see Lun "Percentage Used" from Navicli?  Thanks.
