Hi Maneesh, HCM is a piece of software you run on a PC that interfaces with HCD under z/OS. It is optional and personally have not seen it at any of my accounts.
HCD is a function coming with z/OS that you are obliged to use when building IODF (I/O Definition File) which are used by z/OS as it IPLs, it contains info about devices. Starting with z/VM V4R4, HCD is now available under VM but it cannot replace HCD for z/OS since z/OS needs an IODF and the HCD of VM does not know/care for IODF. In short with HCD of z/OS you can define all you need on your processor, i.e. all kinds of LPAR , with the one from z/VM you can fix VM and Linux LPARs. Following the creation of the IODF file, you would use HCD to create and copy an equivalent IOCP configuration text (old timers call them IOCP deck for deck of cards) from any given IODF. If done from HCD, this IOCP will be compiled into an IOCDS (IO Configuration Data set) and stored in one of four IOCDS Slots on the hard disk of the "SE" (Support Element). One of these four IOCDS is selected when an POR Reset is done on the "SE" to load microcode and I/O device configuration for the benefit of the mainframe hardware. Hope this helps shed some light on these acronyms.

You'll still get some idea of what you're dealing with. However, since you only have a finite amount of lpars, doing this rapidly becomes a limiting factor when you want to have many Linux guests. If you already have VM at your shop, use it. It provides flexibility and ease that LPAR mode does not. IF you don't have VM, start in LPAR mode as VM is a non- trivial expense.

Should we opt for VM directly, instead?

However before going deep into Linux and mainframe, I would like to know more about the administrative part of the mainframe. Please help me with pointers to installation process of any operating system onto bare mainframe. I would appreciate if someone could guide me. Also provide pointers to the vendors for trial version of Linux on mainframe and the pricing of their gamma versions.
