    I am having a hard time figuring out how to mirror one hardrive to another.
    We have a two hardrive machine and what we want is to install oracle onto
    one of the hardrives and mirror it to the other incase of a failure. I want
    through the original installation of Solaris 9 for a new Sunfire 240 server.
    Below is the configuration that was automatically installed. One thing I
    cannot figure out is the backup partition which is on each of the disks. It
    doesn't seem to show up in the df -k. Any help with this would be
    appreciated.

     

    (df -k)

    Filesystem kbytes used avail capacity Mounted on
