can config file be interactively modified

Some hardware changes have been made on an L-class, new disk, differential scsi removed. Do I need to do a re-install or can I modify the config file only?

Why are you needing to modify the 'config' file? Are you referring of ioconfig?

When new hardware is added to the system, if the necessary drivers are already in the kernel, there is nothing to manually modify. You might find it necessary to run insf:
# insf -e

Check your ioscan output. For instance:
# ioscan -fnC disk

Is everything claimed and have a valid description? You do not want to see -1, unknown, unclaimed there.

Install special files to the new device added at hardware path 2/4.0.0:

insf -H 2/4.0.0

Re: can config file be interactively modified

I understood that any hardware changes require a new push from the ignite server. But I notice the hw.info file does not get recreated, this is done once I do a boot client, correct? I was concerned if I had a system failure on a host which had a new disk installed and scsi adapter removed, there might be some pointers to old hw from the current archive that no longer reflect the true system.
