I like using the IBM Microcode Discovery Service (MDS) to perform spot checks on POWER system and adapter firmware levels. This tool gives me snapshot of a POWER systems current firmware levels. I can tell almost immediately if I need to update the firmware on the system or any device installed in the server. This report is especially useful when performing a health check on a customer’s system.
The tool is easy to use. First you need to download the latest inventory scout catalog file from the IBM website. The most current microcode catalog can be downloaded here:
Once downloaded, copy the catalog file to an AIX (or VIOS) partition on the physical server. In most cases, a Virtual I/O Server (VIOS) is the most logical place to copy this file. The VIOS typically owns all the physical adapter devices on the system.
# scp catalog.mic padmin@vio1:
Next, login to the VIOS and move the new catalog file into the correct location for use with the inventory scout (invscout) tool.
# ssh padmin@vio1
$ ls -ltr

Now all we need to do is run the invscout command to create a new MDS upload file (MUP file).

To transfer the invscout 'Upload file' for microcode
comparison, see your service provider's web page.
The new MUP file (vio1.mup) can be uploaded to the MDS tool at the following URL:
In the following screenshot I’ve selected the file to be uploaded. Then I clicked on ‘Upload File’.
I’m presented with the MDS report screen.
Immediately my eyes are drawn to the items highlighted in red. Both the PCIe2 4-Port (10GbE SFP+ & 1GbE RJ45) and PCIe3 RAID SAS Adapter have new firmware available for them. I should update the firmware on these devices! But what fixes are included in the new firmware? Well, directly below the devices report is the ‘Microcode by Type’ table.
I can simply click on the ‘Readme’ hyperlink in the report and a new browser window opens with the readme file for the adapters firmware.
So, should I install these fixes right away? How critical are they? Again, the MDS report provides you with a quick way to answer these questions. Under the ‘Severity’ column, you will see several terms that describe the severity of the related fix. If you click on the word ‘Severity’ you’ll be presented with an ‘Understanding the MDS Report’ window.
On this page you’ll find the definition and description of each severity type. This will make it easier for you to ascertain if a fix should be installed ASAP or if it can wait until the next maintenance window.
I often save the MDS report as a PDF and include it in my health check reports. Alternatively you can save the entire page as a HTML document and send this to the customer. This will ensure the hyperlinks still work and can be referenced by the customer as needed e.g.
By the way, if the microcode catalog file you used to generate the MDS report is not the latest, the MDS tool will warn you. If you see this message, simply download the latest file and send it over to the server where it’s needed and re-run invscout and upload the new MUP file e.g.
“WARNING: the microcode catalog used in surveying host vio1 is now out of date. Version 2014.09.10 was used for the survey and version 2014.09.17 is the most current. We recommend that you either download and install the latest microcode catalog, and run this program again, or run the MDS Applet and allow it to automatically update the catalog.”
