I have created an RPM package, and SRPM package, which I will share here, for smartmontools version 6.5 on RHEL 6. Note that the official version is 5.43 which is clueless with many modern SSD disks. I have yet to test it correctly, and in general – use at your own risk.
I’ve had the pleasure of playing with Ontap Simulator. This is a marvelous tool, designed to simulate a real NetApp appliance, in an easy and affordable manner.

An example – for offline systems, a repo of already installed packages (on exactly similar system) is created for later use. This used to work well on RHEL version…
