Hello Vijay Ayar, Here are the commands that you are going to want to run to clear and reset your physical disk stats. You may need to run the commands on both controllers to ensure that the stats are reset on both controllers.  If you are still unable to clear & reset, then we will need to look at a support bundle to see what is going on. smcli -n -p password -c "clear allPhysicalDiskChannels stats;" smcli -n -p password -c "set physicalDiskChannel [0] status=optimal;" smcli -n -p password -c "set physicalDiskChannel [1] status=optimal;" smcli -n -p password -c "set physicalDiskChannel [2] status=optimal;" smcli -n -p password -c "set physicalDiskChannel [3] status=optimal;" Please let us know if you have any other questions.
