AIX multibos mksysb migration

cggibbo 270000TMUJ | | Comments (4) | Visits (22296)

Tweet
I’ve written about multibos before, here and here . But recently I started experimenting with multibos mksysb migration. A customer asked me how this worked and apart from a high-level view I wasn’t able to provide any real world experience, so I thought I’d give it a try. What follows is just a ‘brain dump’ from my quick test.   First of all this isn’t really a migration. It just simply populates a second instance of AIX with a higher-version. It doesn’t really migrate (or merge) your existing configuration into the second instance. So... [More]

DLPAR not doing it for you anymore?

I received an email from one of my customers recently that simply said:   “mate …on lpar30, for some reason the IBM.DRM and others are failing to start .. um .. any chance you could have a quick look at that ?”   So I asked, “OK, so this use to work right?”. To which I received a relatively confused reply, ” .....yep it did....actually no....it’s never worked....or has it???...I’m not sure... ”.   Based on my experience, the most common issue that prevents DLPAR operations...

Virtual I/O Server and DS5020 disk.

cggibbo 270000TMUJ | | Comments (4) | Visits (23685)

Recently I had the pleasure of configuring a couple of POWER7 720s for a customer. Each 720 was to host roughly 12 LPARs each. There were two VIO servers and a NIM server per 720.   Everything went along nicely and according to plan. In a few days we had both systems built. My steps for building the systems were almost identical to those described by Rob McNelly in a recent post . All four VIO servers were running the latest VIOS code i.e. 2.2.0.10-FP-24 SP-01 . All the client LPARs were running AIX 6.1 TL6 SP3 . Each VIOS... [More]
