Hello grendels_Arm, What I would do is to clear the physical disk channel stats. Here are the commands that need to be run: 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;"  If you are still getting the error after clearing all the channel stats then we will need to look at a support bundle from your MD3000i to see what is causing the error to keep happening. Please let us know if you have any other questions.
I'm getting this error on my MD3000i which we have a MD1000 connected to. All disks show optimal but disk channel 1 shows optimal but disk channel 2 shows degraded.  There a Dell tech here I can send support zip to?
