    Centera Viewer CLI command "show protection" will show the current protection scheme

    Config# show prot

                       Write         Fallback
    ------------------------------------------
    Mirror             0 B           -
    Parity             disabled      -
    ------------------------------------------

    The above shows the protection scheme is mirroring else Parity (CPP) would be enabled and showing a threshold where anything larger than the threshold would be written in parity.  Small objects (250KB or less) should always be written in Mirroring (CPM)

    If its a CPM then the parity will be disabled ?

    so what about the below cluster ;

                       Write         Fallback

    ------------------------------------------

    Mirror             0 B           -

    Parity             250 KB        Mirror

    ------------------------------------------

    Thnx

    If you are on the email list to receive the daily health reports, you can also find this information in the health report.

    Protection Scheme(s):   CPP,CPM  

    Protection Threshold(s):      256000,0 

    In this case, you have CPP with mirrored fallback and a 256K threshold.
