I have a number of Solaris 9 and 10 sparc servers (no RAID) that are custom DVD jumpstarts provided by SONUS Networks for their softswitch VOIP products. The normal install process would be to use the DVD supplied by SONUS to do a reinstall from scratch in the event of failure. Since we deploy our softswitches to unmanned locations, having someone manually do a rebuild and reconfiguration of the servers is not the best. We have out-of-bound access to the machines' ALOMS, so running commands from OpenBoot is not a problem.
I have looked at using puppet in combination with theforeman to provide network jumpstart installs and software configuration, but due to the way the custom SONUS DVDs were created a network jumpstart has been problematic and would require us to recreate the entire install process which would involve modifying the SONUS custom scripts which we don't feel comfortable doing.
The best solution to us would to image/clone a server and then in the event of a failure have the option to do a install of that image/clone from a local linux server. Hopefully being able to leverge DHCP and NFS. Is this possible? Should we do it a different way?
