Building multiple LPARs with dedicated I/O from the CLI

Hi,

Nowadays, I’m preparing for huge hardware delivery. I’m about to get dozen of MMD’s. The challenge is to configure them (LPAR profiles, VIOS, etc) as soon as possible. I found the way how to automate creation of multiple VIO/LPAR profiles including I/O configuration for multiple servers without knowing SN of the expansions drawers.

SR-IOV technology on POWER – my few words

Finally the announcement day arrived. POWER8 and SR-IOV have been introduced to the world, and I can share my experience from my last residency.

Single Root I/O Virtualization are not new adapters, but this is a new technology, standard, specification. In fact, it uses adapters which are on the market for some time already. Specification allows to get a slice of a physical adapter and assign it an LPAR. This feature requires a proper hardware, firmware, and all elements around it.

Managing the Virtual Media Repository

Virtual media repository is very useful PowerVM feature. Some older IBM i administrators probably remember similar function available in iSeries ages ago. In short way, it allows to share CD/DVD images on a frame/server layer.

I use it very often, because it allows load a SLIC without physical access to a server. Practically you can install an IBM i OS, on completely new POWER server, which doesn’t even have a physical CD/DVD drive.

In this post I’d like to show different methods how to manage the Virtual Media Repository. Read more of this post

Backing up a VIOS to an IBM i

If an administrator run a VIOS within IBM i environment only, he needs to do backups anyway.
The most efficient way how to do it, is perform backups to a NFS file system exported by an IBM i .
