This article analyzes "server common problems and x86 troubleshooting methods" with you. The content is detailed and easy to understand. Friends interested in "server common problems and x86 troubleshooting methods" can read it slowly and deeply along with Xiaobian's ideas. I hope it can help everyone after reading. Follow the small series to learn more about "server common problems and x86 troubleshooting methods".

X86 failure may be due to network card, fan, power supply, cpu, memory, hard disk, raid, motherboard, static electricity, etc., as well as various unknown reasons. The following are some common problems, troubleshooting cases, and troubleshooting of IBM and DELL servers shared by community members and compiled by community experts AIX7. Server FAQ Summary

The server supports the information data of the whole enterprise, and it is of great significance to the information storage, business development, normal operation and so on. However, in the daily operation process of the server, due to its complex hardware structure and cumbersome operation principle, there will often be some large and small problems. Here is a summary of some common server problems carefully organized to help you solve problems.

1. System blue screen, frequent crash, restart, slow response speed

Server and our ordinary computer hardware structure or operating system, are very similar. Therefore, just like our computers, it may be infected with viruses, and it will also cause crashes, blue screens, restarts, etc. due to system vulnerabilities, software conflicts, hardware failures, and the same will lead to slow response due to excessive garbage cache information.

2. Remote Desktop connections exceeded maximum connections

Since the server allows 2 connections by default, if you forget to log out after logging in and directly close the remote desktop, the server recognizes whether the login is left on the server side. The most common way to do this is to restart the server, but if it's peak season, the loss of restarting the server is obvious. Then at this point, you can use the mstsc/console command to forcibly log in. Open the "Run" box and type "mstsc/v: xxx.xxx.xxx.xxx (server IP)/console" to log in to the remote desktop forcibly.

3. How to clean files that cannot be deleted

In this case, it may be that the file is still running, you can restart to delete it, or run CMD, enter arrtib-a-s-h-r to delete the folder name, and finally enter del to delete the folder name to delete, run this command can not be restored, please use caution.

4. system port hazard

For servers, stability and security are paramount. Therefore, we only need to guarantee the most basic functions of the server, just like the sound card is prohibited by default. We don't need too much functionality, and we don't need too much port support. Like some unnecessary, and high-risk ports can be blocked. Some necessary and risky ports, such as:3389, 80, etc., can be set to a special secret port by modifying the registry, so that the security risks of the server port no longer exist.

Fault case sharing

1, IBM 3650M3 server external 220V unexpected power failure, and then call, the server can not start, how to deal with?

Follow these steps:

Check whether the server has orange light, check the hardware according to orange instructions, check whether the power supply works normally, AC, no DC is there is power input and no output. Start key does not light up, the motherboard is not powered on. IMM should not be working, unable to view IMM logs. Failure without power, first determine whether the power supply is good or bad, the best way to use is to short the black and green plug of the power supply, the fan can rotate, and most of the power supply is good. Instead, replace the power supply. If it is judged that the power supply can work normally, pull out various boards in the chassis to do the minimum test. If there is a power-on response, it is caused by the board. If there is still no power-on response, replace the motherboard.

2, IBM 3650M4 server hard disk replacement process, two 330g hard disk do raid1, another hard disk 600g hard disk did not do raid1, 600g hard disk damage after how to replace?

Under normal circumstances, the bad hard disk can be removed and inserted into the new hard disk. If the operating system cannot recognize the hard disk, it is necessary to restart the server and reactivate the new hard disk in webbios. The operating system can use the hard disk normally.

2 pieces of 300GB do RAID1, damaged one can be replaced directly.

If another 600GB hard disk is used on a single disk and has failed, the system cannot recognize this disk and the data is gone. After replacement, if it cannot be identified, you need to enter the RAID Web configuration interface for initialization configuration.

In addition, it is not recommended to use a single disk directly, without data protection.

3, lenovo all-round server, user response in recent days when the speed of business is very slow, often stuck no response, after checking the application system has no problem, how to deal with?

First check whether the slow service speed is for individual users or all users. If all users are slow, you need to check whether the CPU and memory occupancy of the server are very high, and then check whether the network card working status is normal.

Network, application, middleware, database, operating system, server, storage will be involved, to do comprehensive analysis. Start from the system level to see if there are abnormal processes, whether the resource utilization rate is reasonable, whether there is a bottleneck in IO, whether there is packet loss in the network, and whether the number of connections is normal... Gradually investigate and expand the scope of investigation.

4. dell server reports W1228 ROMB Batt

< 24hr错误如何处理? 这个报警是阵列卡的电池容量如果在停电的状态下无法使用超过24小时，也就是电池寿命将要完结，这个报警不会影响操作系统运行，即使电池故障也不会影响操作系统，只是在阵列卡上的缓存将被禁用而性能上有所影响，建议您如果服务器在保修期内请致电商家进行报修。 5、更换阵列卡后如何加载驱动? 原来用的是raid1，两块146G的盘现在要加一个raid5的阵列卡，原先的阵列卡不支持raid5所以只能更换新的阵列卡，但是直接用新的阵列卡连接原来的raid1阵列，系统蓝屏重启。请教一下如果在不重新做系统的情况下加载新的阵列卡驱动到系统?因为原系统上面有一套单独购买的录音程序原来的开发公司迁移程序是要费用的。 一般raid1要实现更高级别的阵列扩容，那么首先raid1要支持raid5，即本身两块盘在独立的阵列卡支持raid5、raid1的情况下创建的raid1，那么这种情况下，只需要加一个电池保护就可以实现raid1至raid5的扩容。就你所说的这种情况，两块盘如果不打算加至三块或者三块以上做raid5的话，建议你还是保持原环境，否则出现蓝屏诸如0x0000007B的报错很正常，而且阵列会乱数据有风险。 【提醒：切不可在不做任何备份的情况下，直接更换其他不同型号的阵列卡并开机启动，此类操作很有风险】 6、IBM X3650M3机器重装系统问题? 一台3650安装系统，之前安装linux系统。现在要更换成2003系统，我在ibm官网上下载了serversguide引导盘，通过用引导盘去安装，引导盘启动很正常，按照启动提示一直做，没有任何报错，但是通过引导盘做完后，重启进入系统居然提示"boot fault"，难道是引导盘的问题，又去下了个9.0的版本，结果还是一样，也没有安装完成。当时都不找到是什么问题，raid也是正常的，硬盘也没有问题。 通过用软件将raid驱动和硬件驱动集成到2003iso镜像后，然后在去安装系统，就可以正常进入系统，实在不行硬件驱动也可以单独安装，raid驱动要集成到2003iso镜像中。 7、Lenovo x3650m4服务器更换主板后，无法进入系统，请问如何处理? 针对 2008R2、linux6 以上版本更换主板后无法启动，完整解决办法图文文档，请到社区此链接下载：
