Contingency planning for System Failure

I have inhereted a Solaris 8 server which is running an important application in our production environment.
The dilema is that the server has just one internal hard drive I believe it was installed using jump start, it does not even have a CD ROM drive and root is not mirrored (since there is only one hard drive)
I cannot take the server down for any reason.
The best I could do is take the backup of the entire server from root on a tape using netbackup.
The only comforting aspect is that I have a server similar to this server which I can use in case of emergency which does have a CD ROM drive.
My question is, if the server dies, what can I do now to restore with minimum down time on to the spare server

I was inclined and please correct me if I am wrong is to create a flash archive from root of this server on to another server's spare drive.

Quote:

flarcreate -n flash_root_archive -c -R / -e root_archive -x /anotherdrive/flash -a admin_operator -S anotherserver:/anotherdrive/flash/flash_archive1

If the server dies I can use the spare server, boot it from solaris 8 CD and do an installation using flash archive i have created.

Please excuse my ignorance, but I surely appreciate some guidence.

Thanks
