Many companies utilizing the HP-UX operating system use Mirrordisk/UX to software mirror the operating system to an alternate boot drive. Below is a script using HP-UX agile device special files that can be modified for your specific implementation to use Mirrordisk to mirror the root volume group which by default is vg00. The first script is for the Itanium IA64 CPU architecture. You just have to modify the DISK1 variable, and the last line that specifies the hardware path to the alternate boot drive to which you are mirroring the OS.

Here is an example of an older version of the script for the PA-RISC CPU architecture. In this example we were mirroring the OS to SAN storage, and there were multiple paths to the disk. This version uses the HP-UX legacy device special files and adds in each path separately in the multi-path environment.

In Linux, the above steps are really heulpfl to create new partition. One must need to know about these codes and commands. But, in Mac there are so many third party applications to modify Mac partitions.I have used Stellar Partition manager software to add new partition and resize the the existing one.
