Dumping NIM objects to a script

With all the latest improvements to NIM like "alternate master" and the like, I recently ran across something it doesn't do automatically: Copying a subset of a NIM servers objects to another server.

At work, we have several different NIM masters in different locations. All of them serve the same resources but with different clients. We use rsync to keep the actual data on disk in sync and create NIM objects accordingly(which means that we create SPOTs only once, at the "master master" and copy the SPOT data to the other machines and simply add the SPOT object to NIM without recreating the whole thing).

When the rootvg of one of our servers failed, I simply sent a set of harddisks there, containing nothing more than the base operating system and an old copy of the NIM instance. I didn't need to care about the actual installation images, because they were on a RAID5, but the NIM database was out of sync with what was on the disk.

If you asked me what my current job was, I would probably answer something along the lines of "I create and destroy partitions on Power5
systems for a living" and it's true. On an average week, I install between 10 and 40 partitions spread across several systems.

If you've got that kind of work to do, you wouldn't want to spend your time clicking your way through some gruesame application like
WebSM.. And I can do without it as well.

But I haven't found much help on the net, so I have decided to make a blog entry with my HMC commandline cheat sheet which should get
you on the way to partitioning IBM pSeries systems without WebSM
