    Solaris Disk suite and Mirroring boot disk

    Greg_Kroon NameToUpdate

      Hi Guys

       

      Recently I was doing some research for a POC that has been put on hold .

      One of the requirements was to be able to automatically mirror the boot disk with Bladelogic .

      Below are the commands and references I used to do it in a manual fashion , I have also attached a script I found on Big Admin that automatically does this for x86 and Sparc , with a little tweaking it can run completely unattended .
