Explanation of nouns：
AC Source：Programmable AC power supply.
Grub：GNU GRUB (GRand Unified Bootloader are referred to as " GRUB ") are one from GNU projects
Multiple operating system startup program.GRUB is the realization for starting specification more, and it is more that it allows user that can simultaneously possess in computer
A operating system, and the operating system run is wished in selection in computer starting.GRUB can be used for selection operation system partitioning
On different kernels, it can also be used to these kernels transmit start-up parameter.
The following detailed description of specific embodiments of the present invention.
Present embodiment by taking Ubuntu 14.04LTS (GNU/Linux 3.13.0-24-generic x86_64) as an example into
Row test, testing tool：Server one, AC Source, test main frame one, DV mono-, temperature test chamber one.
1. changing BIOS:Set server to energization Auto Power On.
2. changing Linuxg Grub settings:When unexpected shutdown, it is easy to cause system to rest on grub guiding interface, need
Carriage return could enter system, at this moment change system configuration file, and vim/boot/grub/grub.cfg finds following one section, will
Timeout=-1 makes timeout=2 (being more than zero arbitrary number, unit is the second) into.
fi
terminal_output gfxterm
If [" $ { recordfail } "=1]；then
This journey -1 (is changed to 2) by set timeout=-1
else
If [x $ feature_timeout_style=xy]；then
Set timeout_style=menu
3. by the external test main frame of serial ports, OCTOPUS softwares are run, state when monitoring BIOS starts (also may be used herein
Equipment to meet other monitoring bios, such as the more advanced equipment of Intel ITP), the display of Connection Service device, side are recorded with DV
The case where being reappeared at that time according to the time of log records when just pinpointing the problems.
4. changing system configuration file：Modification system to realize automatic shutdown after booting, and records the available machine time,
Cp/etc/rc.local/etc/rcbackup/ backup rc.local original documents/
The file that newly-built one of touch/root/log/ is used to store log/
Vim/etc/rc.loacl/ changes rc.local, and following code (two kinds of different schemes) is added inside file：
(1) how many times (number for being successfully entered system) need to be successfully started up by script design server：
(2) being powered by AC Source setting servers, (i.e. server is powered not necessarily enters system to startup how many times
Number)：
date>>The available machine time of log/every time is recorded in inside log files/
Sleep 10/waiting ten seconds/
Poweroff/shutdown/
After the completion of the number of AC Source settings to be done, booting enters single user mode, executes cat/etc/
rcbackup>/etc/rc.local
5. chamber and AC Source settings.
In order to make server completely it is cold, we set server energization 5 minutes, then power off it is cold set 15 minutes, need
Chamber and AC Source synchronous matchings are completed.It is first that server is cold at -5 DEG C to set 2 hours, the temperature after equipment is completely cold
Degree rises to 0 DEG C, and server is powered, and (maximum time of the equipment from energization booting to automatic shutdown of shutdown in ten seconds is waited for after energization
It is 5 minutes, is more than to calculate fail).In order to ensure server can be cold, temperature is reduced to -5 DEG C from 0 DEG C after device powers down,
It is stood at -5 DEG C and restores 0 DEG C, then the booting that is powered after five minutes, shutdown ceaselessly recycles, and after the completion of test, server need to be in room temperature
It is lower to stand two hours.
This process is as shown in Figure 1.
If equipment needs are sold in worldwide, AC Source can also be set, will be owned in the world
Each test 50 times of mainstream voltage type, i.e., the amplitude and frequency of that the five minutes voltages that is powered every time need to include the class of following table
Type, each type test 50 times such as following table：
6. collecting test log：A. the log ,/root/log of available machine time record, order：Wc-l/root/log can be looked into
See the number being entirely switched on, concrete analysis can be calculated by excel and is switched on twice interval time, if the time must more than 25 minutes
So there is the case where boot failure.When b.bios monitors log boot failures, corresponding bios leader records c.linux can be checked
/ var/log/syslog, by being switched on, log and bios log can only have found whether booting is normal, checks that syslog can be seen
Whether shutdown has exception, bios normal boots system but system, and there is no the log normally started.D.DV can help to reappear booting
Specific situation when abnormal or shutdown is abnormal.
Patent of the present invention discloses a kind of a kind of test method of test server cold-starting, by AC Source
And the setting of script, after making equipment and component every time cold start it is right in the case where equipment also has residual temperature to prevent
