I’ve been doing many AIX server migrations lately. Some which involve taking a mksysb and restoring, others which involve presenting LUN’s from a SVC and then doing a migratepv. The latter can result in a large number of disks presented on the host, so I wrote a quick basic script which gives me the details that I need – hdisk name, size, vg, pvid and serial number.
Maybe someone out there will find it useful.
If 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
This 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.
