2014 in review

The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 11,000 times in 2014. If it were a concert at Sydney Opera House, it would take about 4 sold-out performances for that many people to see it.

Extreme fan noise with an HP ProLiant ML110 G7

A little while back I posted some initial impressions of the Hewlett Packard ML110 G7, and noted:

“One review made mention of the ML110’s quiet operation and how it would not be noticed in an office environment. Well, unless your office happens to be on the factory floor of an air conditioning manufacturing plant, you’re going to notice this thing…”

Out of curiosity I decided to look into this a bit more. It turns out a whole bunch of other folks have encountered the same thing, and if you perform an online search for “HP ML110 G7 fan noise” you’ll find many forum posts with all manner of straw clutching – from running every firmware and BIOS update under the sun, to nuking warranties with third-party cooling hacks.

One thing I noted with my unit was the actual reported fan speeds via the LOM were in the order of 31%/13%/10% for the three fans respectively – which hardly accounts for what sounds like a system with its fans running absolutely full tilt (completely unsuitable for office operation).

Buried in one forum post was information apparently passed on from HP’s support personnel to an affected customer, advising them to reseat the front fan (referred to as the PCI fan in the service manual), as apparently it may become dislodged during shipping. Sounded rather odd to me as clearly the fan itself is functioning (a bit too well…), but as it turns out this totally nailed the problem. After disconnecting the fan’s motherboard connectors and physically removing the component, then letting the system boot, POST and shutdown with a fan error, then reconnecting everything and powering it back up, the server is now quiet.

Updating iLO3 firmware on an HP ML110 G7

Hewlett Packard’s website is an embarrassing mess. Don’t go looking for an easy-to-find page for the iLO3 with a one-click firmware download, because you won’t find one. The state of HP’s site is a rant for a future post, but for now here’s a quick guide to getting your hands on the latest iLO3 revision. The sole catch is that you’ll need a Microsoft Windows-based PC at some stage, irrespective of which OS you have installed on the server itself (OpenIndiana in my case).

First, go to HP’s product page for the ML110 G7. Next, we’ll choose “Microsoft Windows Server 2008 R2” (blech…) as our OS:

HP ML110 G7 product page

Look for the Lights Out Management Firmware section, and click the relevant link to start the download (we’ll go for a 64-bit Windows target OS):

Download the iLO3 installation file

Now, run the downloaded executable file (named “cp022549.exe” in this example) on a Windows-based system (Windows 7 or Windows 8 will do just fine) and extract (not install) the file contents to disk:

Extract the downloaded file contents

Look for the .bin file in the extracted files – this is the one we need:

Look for the firmware BIN file

Now, go to the iLO3 admin BUI, upload the .bin file, and wait for the update to complete. Once the LOM reboots, verify the firmware version:

Prepare to upload the BIN file

Firmware file is uploading

Updating to the latest firmware

Before:

Compare the old firmware version to the newest

After:

iLO3 firmware is now at the latest version

Fixing TeamViewer on Ubuntu 64 bit (tvwine.dll.so)

Folks running older versions of TeamViewer (version 6 for Business in my case) on the 64 bit (i.e. the default download) release of Ubuntu may have run into the following error after installing and trying to launch it:

In short, the solution which worked for me is in this post:

I’m still reasonably happy with TeamViewer – it works well, and they’ve as yet resisted the urge to railroad their customers into a rental-only model. It’s for this latter reason I’ll be sticking with the product come time to upgrade.
