I've a XIV G3 array (11.1.1 microcode) connected to Solaris 10 host running Oracle DB. DBA is complaining of slow performance from some time and sees high IO waits and response times. We have a QoS limit on this host set-up sometime back (way before DBA started seeing issues), but not sure if that may be a contributing factor. Has anyone worked on similar issue, could you tell what to check on the XIV Statistics to understand if array is the problem. Thanks!
