Automated Microcode Management System
One of the most difficult administration tasks in an AIX environment is attempting to keep the firmware and microcode up-to-date. Mt Xia has devised an automated method of gathering the Microcode information, determining which microcode needs to be updated, generating reports, and uploading the required microcode updates to each individual system.: One of the most difficult administration tasks in an AIX environment is attempting to keep the firmware and microcode up-to-date.

Calculating the size of a Virtual Processor
This document describes the algorithms used to calculate the size of a virtual processor when using shared processors in an LPAR. The IBM documentation describes how to calculate CPU utilization, NOT how to size for configuration, this document clarifies this process. A description of the HMC input fields for the processor tab is included.: This document describes the algorithms used to calculate the size of a virtual processor when using shared processors in an LPAR.

The following procedure is specific to an LPAR named "dalapvio01" but is representative of how to configure etherchannels on all VIO servers in the Mt Xia environment. This procedure removes all existing ethernet devices and reconfigures them from scratch. This has been found to be the best method for configuring network devices on the VIO server.
