Thank you for your effort. I believe mksysb doesn't include the memory of the OS in the snapshot, isn't it?

wpm,

Right. It includes the whole rootvg plus a bootloader (if tape/DVD), but not memory/paging.<br />
<br />
Recovering a machine by means of mksysb implies booting from this image and a complete restore of rootvg.

So if I'm having some other VGs it won't include them?

mksysb is for rootvg exclusively.<br />
<br />
There is a similar command &quot;savevg&quot; for non-rootvgs (and rootvg. but see below!)<br />
<br />
It works nearly the same way, but will not create bootable media.

Hi,<br />
<br />
I'm having a VIOS (LPAR) that I'd like to fully backup before installing some packages in it. I'd like to be 100% sure that I can restore it to the actual state (including memory processes - just like in vmware esx - the memory snapshot option).<br />
<br />
Is that possible?<br />
<br />
A BIG THANK YOU!

PowerVM - AIX LPAR Snapshot with memory snapshot?

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Unix OS

A mainframe operating system is networking software infrastructure that allows a mainframe computer to run programs, connect linked machines, and process complex numerical and data-driven tasks. Modern mainframe design is generally defined by redundant internal engineering, extensive input-output facilities, strict backward compatibility with older software, high hardware and computational utilization rates and high stability and reliability. Well-known operating systems include IBM z/OS, z/VM, zTPF, z/VSE, OS/390, and their predecessors, along with MCP for Unisys ClearPath, and NonStop OS/Guardian on HP/Tandem, and questions regarding the IBM midrange operating system called IBM i, OS/400, and i5/OS.
