Op Manager 8 unable to display server disk partition info

Op Manager 8 unable to display server disk partition info

Hi,

Currently we are using Op Manager 8.I've tried to generate report by choosing:

Reports>>Disk Usage by Drives
           >>Volumes with Least Free Space
           >>Volumes with Most Free Space

It did display the info but not all server partition info (6-7 server partition info).Suppose it should display all 24 servers that in the server list.One more thing the report cannot capture total space and only displaying NA,able to capture free space but only for few servers.For use space and  use (%) column I also  experienced the same thing.
All the server credential details is verified ok.This problem only happen for the said reporting option only.For other reporting there's no issues.I've attached the screen shot for disk Usage by Drives

Please help

thank you very much
