There are two things here-> One Drive performance and another one drive error
If you want to check drive performance then I would suggest to refer output of "show disk-statistics". If you are facing performance issue then capture the same output 5 to 10 times during that time and give 2 to 3 minutes interval between each output capture. From each output look for IOPs value. You need to check what is the drive model and accordingly what is the safe IOPs value could be (Google will help you). This also depends upon what is the IO size ? If any drive crossing safe IOPs value then you should check for hardware errors for that drive. If many drive crossing safe IOPs value then it should load issue which you need to control from host end.
Now coming to drive errors, I would suggest to do MSA health check with below tool and that will guide you what need to be done,
>> Download MSA Log File from the MSA Storage Management Utility (SMU)
>> Upload MSA Log File in the MSA Health Check website
>> Review Results by clicking through the tabs and saving the PDF report
>> Take Action and start improving your MSA availability
There is no cost to use the MSA Health Check. Upload your log file today and check the health status of your MSA.
YouTube video giving a quick overview of MSA Health Check
It is also worth mentioning that embedded in the MSA Health Check Tool (www.hpe.com/storage/MSAHealthCheck) are two excellent videos showing how to save your MSA log file.
One video is for Storage Management Utility (SMU) version 3 (MSA 205x/1050) and the other video is for SMU version 2 (MSA 204x/1040 and P2000 G3).
