? remember once the Dell R720 server ESXI5.5 system down the wonderful experience ?

Summary point: 1, do not see the reason for downtime. 2. Reset Bois for no reason. 3, do not look at the log. 4, Dell r720 server memory needs to be inserted sequentially, such as: A1,a2,a3,a4. 5, use Idrac to manage the page remotely. 6, to have their own judgment problem thinking, do not depend on everything 400. 7, do not pay attention to the problem, otherwise it will not directly restart the device.

Failure point one: not see the reason for downtime

When I was working with a virtual machine on the server at 5 o ' Dayin the afternoon , the mstsc window was suddenly disconnected. Ping also ping , I did not think of anything, directly rushed to the computer room to restart the server power, (the server has no monitor, also did not expect to see what the situation) and then back to the workbench to do other things, after about ten minutes ,Ping the server,Ping does not pass, a think bad, play big, I went to get the monitor, keyboard to see the situation. A look at the situation

Hint No Raid, Odd Strange, in the spirit of customer service first, on the dozen , I guide me to see the hard disk,

All aspects of physical hard disk display are normal, the state is normal, so I told me that the hardware is no problem, that is the software caused the problem, that is, the system, let me re-do a raid0, re-install the system. But this problem is not solved, (if I listened to the first , my data is not long).

This is the next day, the number .

mistake point two: should not go to reset BIOS

finally with the customer service e-mail discussion, I said to see if the startup item is not the problem , from the hard drive to try, I went to try to boot from the hard disk, display DHCP ... That is, I did not find the system, I will try, choose Drive C finally succeeded,

It can be started, but the problem comes again.

boot to this interface is stuck, I looked at the time to estimate is the BIOS setup problem, I went to reset the BIOS.

then restart, and then stuck in this interface. Then I press a few times to enter the Vkernel load success When the purple screen is displayed immediately.

see this I went to the internet to check, found the method:1, update the system, with the latest, the problem is the right e- card received large traffic caused. 2, turn off the BIOS cpuid,3, turn on the VT function

If you find a way, try it.

1, the installation of a new system, is also in this interface on the purple screen, estimated or the BIOS setup problem, 2,bios inside there is no cpuid this option, 3,bios inside the default open VT function.

There 's no way to get help. 400

let me provide these wrong photos, I said it is estimated that there is a problem in my BIOS setup, and then he let me configure the BIOS, mainly the system profile Settings this one.

Then reboot into the system, or get stuck in the init interface, then go to the purple screen

The error message is reduced, I am more convinced that it is the BIOS setup problem, back to the workbench, went to the internet to search the BIOS settings (this time, I am restoring the problem), Look at the settings feel that they set up no problem, this time to come, came to the conclusion that my system CD has a problem, I first back he said "CD-ROM No problem", send the past a thought, this problem is not installed at the time of Ah, and then back to a past. Description of the situation. And let me set the startup item, the startup item is the same as the set item provided in the.

It's almost time to get off the clock and send a message. Let me re-download The Dell customized esxi5.5 custom system and update the BIOS. Today, even if a day is wasted, the work is not done, the server.

+ number

Critical discovery: Memory error log

today I opened the Idrac, this would like to start the next device, (boot into the F2, has been too tired, on the internet to search the remote management, saw this Idrac, also yesterday, to see the virtual desktop , you have to upgrade to the Enterprise version, the upgrade must buy a license), and then went to the next log.

Search for translations on the web, prompt for memory errors, recommend the operation Reseat the memory

to this situation and said the next, confirm that there is a problem with memory,I put the memory card for the slot, I follow the done, restart the device, the hint can not find memory, I have a heart spleen lung kidney ah, had to re-dismantle the machine reseated, restart, The system can go in, haha. But when I went back to the station to see it, I found that the memory was only 8G. I have 16G , and then go to read the diary (learned, know to read the diary)

This display A1,A3 no memory card detected

The screen also displays errors

This error shows A9,the A11 memory function is turned off, indicating that the memory should be placed next to

combined with 2 errors, 4 memory cards were inserted in A1,A2,A3,A4 4 Slots (A4 Forget in which place, do not mark, lest misleading), so restart the device,ESXi host can use.

lasted one hour.

Note: 1, during the constant press shutdown, start entering the f11,f2 time is very long, sometimes press the not necessarily into the settings interface, once I have 4 consecutive restarts of the device has not yet entered the Setup interface. This operation wastes a lot of time. 2, during the constant want to redo the ESXi system (customer service has been let me redo the system to try), tried a variety of methods. Wasted a lot of time
