HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)

Multiple Boot (One Single-Core Server, Multiple Operating Systems)

HP Integrity Servers are capable of running multiple types of operating systems (for example,

HP-UX 11i, Linux, and Microsoft Windows). Depending on your server model, multiple versions

of these operating systems might also be supported.

If you only have a single available core, you cannot have multiple operating systems running

simultaneously. However, you can have multiple boot disks (or logical boot volumes), each

containing a different operating system, and you can choose which to boot from on any given

boot.

On HP 9000 servers, you can also have multiple versions of HP-UX (or other supported operating

systems) installed on different disks (or logical boot volumes) and select your desired boot volume

at boot time.

NOTE: This multiple boot capability works equally well for servers with more than one active

core. It is presented here because this is an available function for servers containing only one

active core.
