This is just a status report on my original post:
* I had a couple of suggestions for commercial products.
(I'm just not really sold on either of the suggested offerings to
give me what I need.)
* I had several requests for information on any solutions I might
find. (I'm not the only one worring with this.)
I don't have a SUMMARY ready yet, but responses from the list and my
research has yielded interesting things:
* As of Solaris 9 4/04 you can incorporate the creation of SVM volumes
via jumpstart. (Thanks, Alex Theodore) Using the 4/04 or later
jumpstart with a flash archive could be the beginning of "quick
clone" recovery. Maybe. Anyway, this doesn't help with my current
situation, I have Solaris 9 4/03.
For those of you who want to play along at home, the trick is to have
a fast, simple, load-and-go bare metal recovery for a system which is
setup with SVM meta-devices. If you are not at Solaris 9 4/04 or
later, the meta-devices are the stumbling block. Since I am not at
the 4/04 level, I can't say if it is the complete cure.
Also, Veritas is not part of my picture; I'm working with what is
provided by SunOS 5.9 Solaris.
At such time as I come up with my plan, I will post a real SUMMARY.
