Our sister company has an 8203-E4A installed with V6R1. &nbsp;Since we're a software company having to support customers running V5R2, we have a separate machine running V5R2, but it's out of warranty and it'll be so expensive to upgrade it to V5R4. &nbsp;Is it possible to create two LPARs on our sister company's machine with one running V6R1 and another running V5R4?<br />
<br />
Also regarding LPAR's -- does it make the machine behave like two separate systems? &nbsp;Is it possible to have one with system date in Pacific and another in Eastern Time, for example?<br />
<br />
Thanks so much for your input.

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
