    Hi All,

    We have high impact on perform still not able to find the root cause why we have performance impact.  I am from SAN storage end, need some suggest how to overcome this performance issue.

    As of now OS reporting us because of disk error which is causing the performance but I did deep analyze and found.

    Disk error from both the cluster node found on remote frame not on local frame

    That is from production having disk error from DR frame remote frame.

    Same from DR node having disk error from production frame remote frame.

    Then I checked the powemt output from both the node we are getting I/O error only from remote frame not from the local disk. What I mean to say they have performance lag when it write the data to remote disk not on local disk.
