VIO: Virtual Media Library
0The first LPAR that I normally build post VIOS installation is a NIM LPAR. Once you have your NIM server setup, building the rest of your LPAR’s becomes a much simpler task. However, what do you do when there isn’t an existing NIM environment, or you don’t have access to the physical servers to insert a disc to perform the AIX install? This is where the Virtual Media Library comes to the rescue. The Virtual Media Library is a feature of the Virtual I/O Server which allows you to present an ISO image to underlying LPAR’s. The best thing about the Virtual Media Library is that it’s very quick and simple to set up.

Upgrading your AIX environment using multibos
4If you haven’t clued on by now, AIX is my operating system of choice. I’m sure there are many arguments for and against, but looking at it from a systems administrator view point, it’s second to none. Anyway, that’s a story for another time. What I’m writing about today is patching your AIX installations using multibos. Now before I get started, I’ll stress two points:
1) Chris Gibson has already written two great (and far more in depth) articles on multibos, which I recommend reading before going any further (Links: here and here).
2) This blog of mine serves two purposes; To share some of the things I come about during my sysadmin activities and secondly also a dumping ground for documents I write for myself. This post is the latter, as multibos isn’t something that I use daily (maybe a few times a year), and really, who’s going to remember all those syntax switches 
Now, assuming you’ve read both articles, I don’t need to go into the benefits of multibos and I’ll dive straight into the how. I’ll be working on upgrading an AIX instance running 6100-05-01-1016 to the latest ML which at the time of writing is 6100-06-04-1112

CSM Commands (dsh, dping, dcp and dshbak) for AIX
4Cluster Systems Management (CSM) software provides a bunch of tools to manage from a single point of control your AIX environment. There are a number of commands available[1] but the main four which I find quite useful are dsh, dping, dcp and dshbak. In this post, I’ll go over each command and some of its uses.

Very quick and basic shell script to show total/free/used memory on a host running AIX.

Mounting external USB NTFS drive to FreeNAS
3This is a quick post on how to mount an external USB NTFS formatted hard drive (or memory stick) to FreeNAS. All that’s needed is to load the fuse driver, but it had me stumped for a bit until I found it in a forum post.
First things first, let’s plug in our drive and find out the device ID FreeNAS assigns it.
