Here is a thought that I have kicked around for months.
Anyone, feel free to spend months working out the details and
let us know where you end up <grin>.
I believe most (if not all) UNIX platforms have the ability to
boot as diskless workstations.
In the process of doing so, a machine downloads a kernel image
(via RARPd and tftpd), boots, mounts filesystem disk and swap space,
and executes initialization scripts off the mounted filesystems.
A Solaris Jumpstart boots as a diskless client at first, then executes
a series of scripts to build an entire system from ground up. We used
this to do a complete ground up installation on over 1,500 Solaris
workstations. -Including backup and recovery client code.
Why can't this paramigm be extended to include executing an automated
recovery from ADSM. I see no reason it can't!
In effect, you will have build a one command ground up disaster
recovery.
--> "boot net - install" would do it.
