Scanning for new LUNs on Linux servers
Storage management, the joys! Storage administration is one of those tasks that every admin does, and depending on your growth it may be something that consumes a lot of your time. If your servers are connected to a Fibre channel or iSCSI SAN, you probably need to periodically poke your systems to see new storage that is made available to them. There are several tools that can be used to do this…

I've been a fan of KVM for quite some time, and gave a talk on it a while back. The KVM design always made sense to me, and I tossed Xen out the window the minute I started using it.

Due to some time constraints I cancelled my microserver order and re-used a server I had at home…

With the introduction of RHEL6 our beloved kudzu was removed from Redhat Enteprise Linux (it's been gone from Fedora for quite some time). If you're not familiar with kudzu, RHEL5 and below use it to detect new hardware when a system is bootstraped. All of the functionality that was part of kudzu is now handled by the kernel and udev, though a lot of sites will need to support RHEL 5 systems for years and years to come. I was curious how kudzu detected new hardware, so I started reading through the kudzu man page and source code…
