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

cdsd

cdsd(1m)																  cdsd(1m)

NAME

       cdsd - Starts the CDS server

SYNOPSIS

       cdsd [-a] [-D] [-l principal] [-w route]

ARGUMENTS

       Creates a new namespace if there is not an existing namespace. This flag is meaningful only when the cell is first configured (that is, the
       initial creation of the namespace).  For debugging use only. Causes the cdsd process not to fork.  Locksmith  mode.  Allows  the  principal
       specified to have full access to all information stored with this server.  Routes serviceability messages.

DESCRIPTION

       The cdsd command starts the CDS server.

   Privilege Required
       You must log in as superuser (root).

NOTES

       This  command  is  ordinarily executed by a DCE configuration or startup script. You should use this command interactively only when a cdsd
       fails to start automatically after a reboot, or if you want to restart a cdsd  after disabling it to perform a backup or to  do	diagnostic
       work on the host system.

EXAMPLE

       To  restart  a cdsd server, follow these steps: Log in to the server system as superuser (root).  Verify that the dced and cdsadv processes
       are running.  Enter the following command to restart the CDS server: # cdsd

       When the server process starts, it starts all clearinghouses on the system.
