Proliant MicroServer G8 – Red Alert

proliant

Through this article I will share with you the bad experience I had with my Proliant Microserver G8 few days ago, concerning the blinking red-light problem on the front panel. If you are here, it is probably because you are encountering the same problem and I will reassure you: your server is probably not dead 😉 .

The symptoms are the following:

  • Instability of the server (inopportune reboot)
  • Sometime rebooting before the POST procedure to finish
  • Blue light on the front panel switch to a blinking red-light

Check your ILO log

Very simple step but it was not my first thought though. When you check the manual, Fast-flashing red (4 Hz/cycles per sec) = Power fault. Your first reflex was probably to remove all your hard disk, hoping it’s just a power supply problem. I was looking on many forums on the Internet, and some people have solved this issue… by changing their motherboard.

You have better chance to check the ILO log in fact. If you forget your ILO password, you can check this post. My log was specifying that a thermal power shutdown occurred. After disabling this protection feature in the Microserver’s BIOS, I noticed that it doesn’t solve the problem.

In ILO, I also noticed the thermal sensor n°1 (the one for the ambient temp.) was indicating 83°C or -1°C sometime.

temp_ilo_2Observing that the bottle of water on my desktop was not icing or boiling, I removed the faulty sensor from the case.

After that everything went back on rails. Fun fact about the status of the sensor I just removed, ILO still indicates that the status is OK. Also, if you wish to replace this sensor, it will cost you 35$! But don’t be fooled, the sensor is just a KN3904 NPN transistor that will cost you few cents.

File storage strategy

storage

Hi there!

These last few days, I’m emerging from the soil my army of hard disk that contains all my data for the past 10 years. I had been totally discouraged by the amount of information, and huge quantity of duplicated files due to multiple backups.

As I’m storing a lot of files in a year, I searched a good way to organize, sort and backup all my documents, videos and music in a logical way. The purpose is also to reduce risks of losing files (after a hard-disk failure for example). If you are or were in the same case, this little guide is for you! Throughout this bunch of lines, I will show you how to keep the control on your files and your workspace, and how to jungle with your personal and professional data.

1. Know your data

It seems to be obvious to many of you. Sometimes, we don’t realize the quantity and the variety of files we have. The first step is quite simple : take a paper and a pen, and plug your hard-disk one by one. Note down their model, the size of the hard drive, free space, and what they contain. For example :

Seagate 500Gb (IDE): 154Gb used

-Backup from 12th. February 2012
-Some music given by Alex
-Photos
-First C programming project

Western Digital (SATA):
-Blah blah…

Often, you will not have enough space on one drive to put all your file, even after the final step of classification. It is for this reason it is interesting to know the size of all your hard disk.

2. Categorize

As I said in the introduction, your PC could be shared between your professional life and your geek life (Oh! I beg your pardon, I should say ‘private life’ 😉 ). After reading many advises on forums and article on the web, I decided to put each folders/files in a specific root category:
