8 CHAPTER 2. INTRODUCTION
2.2. When the server is dead
Obviously, fixing hardware defects is not possible using a remote management device. Nevertheless
LARA gives the administrator valuable information about the type of a hardware failure.
Serious hardware failures can be categorized into five different categories with different chances to
happen
2
:
1. Hard disk failure 50%
2. Power cable detached, power supply failure 28%
3. CPU, Controller, main board failure 10%
4. CPU fan failure 8%
5. RAM failure 4%
Using LARA, administrators can determine which kind of serious hardware failure has occurred
(see Table
2.1 ).
Table 2.1.: Host system failures and how they are detected
Type of failure Detected by
Hard disk failure Console screen, CMOS set-up information
Power cable detached, power
supply failure Server remains in power off state after power on command
has been given.
CPU Controller, main board
failure Power supply is on, but there is no video output.
CPU fan failure By IPMI or server specific management software
RAM failure Boot-Sequence on boot console
