VNX SPA Read Cache Hit Ratio seems to high

Jump to solution

Hi Community,

I am seeing a high value of 682% for the Read Cache Hit Ratio on our VNX SPA. SPB is only 66%. I am new to VNX, and so I am not sure if this is an acceptable value, or something I should be be concerned about.  Any input would be appreciated.

Thanks,

Found the answer to my question. I was advised by EMC Support the high Read Cache Hit Ratio was cosmetic due to our System being a couple code revisions behind. A temporary fix to get the value to show properly is to restart Unisphere Management Services. The permanent fix is to upgrade to the latest code.

Thanks,
