Using flar
Hi

I have systems running UFS and ZFS file system type, and I need to create images of them ( in HP-UX ) we call it ignite, but in my case I dont have tape drives attached to the servers. I have read about flar archives, but the do I have to create those images in single user mode or using the current run level?

Assuming you are on Solaris 10...
Check here:
Oracle Solaris 10 1/13 Installation Guide: Flash Archives (Creation and Installation) - Oracle Solaris 10 1/13 Installation Guide: Flash Archives (Creation and Installation)
and here:
Oracle Solaris ZFS Administration Guide - Oracle Solaris ZFS Administration Guide
first. If you have questions, come back.

To answer your question flash archives do not need to be created in single user mode. They can be created in multi-user mode BUT you should do that when the system is as quiet as possible, not under load.

ok, so after creating a flar archive would it be possible to provision other servers with this flar file

Depends what you mean by "provision"?

Flash is usually used (1) for disaster recovery and/or (2) to clone a system.

Whether recovery or cloning the new system has the same node name, ip configuration, and other configs as the original. Be aware of that.

Why don't you want to do a fresh install?

what I really want is to have an image of 4 servers and keep it in another server on the network, or use one server as a template to create other installations

So if this other server has enough disk space to store the capacity of the four production servers, why don't you configure a NFS share (or 4 NFS shares) on it and backup each of them over the network? Does that do what you want?
