i am having a strange problem. I have mapped a LUN from Hitach Storage system of about 1TB as a Clustered Disk to our DB Servers. The problem is : if I see the % of disc usage from the 'Hitachi Storage Navigator' , it shows a usage of 98%, where as in actual the usage is less than 30%. I tried the 'Reclaim zero pages' option but it didn't workout.
Kindly help, if there is something else needs to be done.
Thanks & Regards,
