Solaris

It's a DHCP server. We want to make a clone for fail over purpose since there are some identical systems available here. We do have a secondary DHCP server.

Hardware: Sun v120. OS: Solaris 9. Two disks without array, /var and /opt on the secondary disk.

How can I clone the system via network or serial port? Any idea?

Thank you in advance!

So as an AIX lover, you want to create a mksysb image on a NIM server ready to deploy a new client?

I think that Jumpstart is the Solaris term for it. I used to do it, but it's been 10 years and I've forgotten. I think we used to use ufsbackup to tape and then restore, because it was in the days before 100M ethernet even. A quick search of these sorts of terms turned up BigAdmin Feature Article: Using Solaris JumpStart With the Solaris 10 OS for x86/x64 Platforms if that's useful.

An alternate might be (if you have an identical server up and running) with a spare bootable disk (assuming it is c0t0d0 source to c0t1d0 on the target)

Code:

dd if=/dev/rdsk/c0t0d0s2 | rsh $target dd of=/dev/rdsk/c0t1d0s2

You would need to set up remote shell on the receving target server before you run this. If all goes well, you should be able to then:-
Take care with this. You could easily upset the current live server or perhaps overwrite the wrong target disk. High caution is advised!

Because of the risk, no guarantees are included with this post and no acceptance of liability will be accepted for losses to services or consequentially losses to any parties dependant on them.

Apart from that, I hope that this is helpful pointer.
