3par one cage's disks have very high I/O error count

All disks of cage2 have 200k -300k I/O error count, but all other disks in the other cages only have less than 10 error.

How can I locate the root cause? Does the cage or the cables have issue?

Hi Louis,

This requires log analysis and active troubleshooting. I recommend you to open a support case with HPE.

Sorry, this array is out of service. 

Could you help me?

Is there any command to test the link quality?

Hi

Take a look at the following page, it list some of the command needed to verify the health of the array

https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=emr_na-c03943974

I'd start with a checkhealth and then maybe check the sfps on each of the cages to ensure the light level is ok (showcage -sfp -ddm cage#).
