    Ive not used concurrent I/O before, so i just want to check what im doing is correct.

    I have a system being built with Oracle 10g & SAP ECC6.0.

    I have laid out the filesystems as below, and have mounted the oracle data, archive, redo, mirror filesystems as namefs with cio.

    The parent /oracle filesystem is moounted normally, so that binaries and other non cio files do not use CIO, only the specific filesysystems mounted with namefs.

    /dev/oracle_lv /oracle jfs2 Oct 31 11:44 rw,log=/dev/loglv01
    /oracle/P00/sapdata1 /oracle/P00/sapdata1 namefs Oct 31 14:07 rw,cio
    /oracle/P00/sapdata2 /oracle/P00/sapdata2 namefs Oct 31 14:07 rw,cio
    /oracle/P00/sapdata3 /oracle/P00/sapdata3 namefs Oct 31 14:07 rw,cio
    /oracle/P00/sapdata4 /oracle/P00/sapdata4 namefs Oct 31 14:08 rw,cio
    /oracle/P00/origlogA /oracle/P00/origlogA namefs Oct 31 14:09 rw,cio
    /oracle/P00/origlogB /oracle/P00/origlogB namefs Oct 31 14:09 rw,cio
    /oracle/P00/mirrlogA /oracle/P00/mirrlogA namefs Oct 31 14:10 rw,cio
    /oracle/P00/mirrlogB /oracle/P00/mirrlogB namefs Oct 31 14:10 rw,cio
    /oracle/P00/oraarch /oracle/P00/oraarch namefs Oct 31 14:10 rw,cio

    Also, is there any way to configure so that the namefs mounts are mounted with the mount group ?

    Cheers

    Alex
