Top 10 server maintenance errors

This article sorts out the top ten mistakes that are easy to make in server management to remind the network administrator to take proper measures at work.

Server Maintenance Error 1: UPS (uninterruptible power supply) usage Problems

A store is squeezing the final life of its network system. Although the very old server is almost difficult to meet the needs of store operations, the operator is not even willing to replace the battery in the UPS. In fact, the battery

It should be changed every two years. One day, the UPS was too old to control the safe shutdown of the server. Most of the battery energy has been exhausted, so it will soon become useless. As a result, the Controller for preventing and controlling exceptions does not properly shut down the server. The daily normal operation and transaction of the store depend on this server. It takes three days to repair the server, and it takes longer to compensate for the resulting loss. In fact, a battery worth only $75 can effectively avoid the above.

Server Maintenance Error 2: not finishing what is needed

A phone call is sent to the headquarters of the company, saying that the server of a branch has a problem. The Network Administrator rushed out of the office and drove an hour to the location where the accident occurred. As a result, he found that part of the operating system file was damaged, so that all he could do was reinstall the operating system. The Network Administrator of the branch can't find the installation disk at the moment. It doesn't matter. The administrator of the Headquarters has it, but in his office-one-hour one-way trip and two-hour round-trip. Pack your backpack and carry it with you. All the things you may need, including the operating system backups used by your users, should be put in your backpack. This is easy to implement and does not need to be spent, but it plays a key role in updating the operating system.

Server Maintenance Error 3: No patch is installed

An error occurred while connecting the server of a toy manufacturer. As a result, all staff members lost contact with their files and the production was forced to stop for two days. Serious losses! A recently hired Network Administrator is responsible for solving the crisis. He soon discovered that the previous network administrator did not install patches when installing the system three years ago.

Patches are provided free of charge. Maybe they are not open, but they are usually easy to configure and can be done by any system administrator. The former Administrator said that because the system runs well, no patch is required. This statement is obviously irresponsible.

Server Maintenance Error 4: Improper backup

A hospital's office stores a lot of medical files and medical records. Because no information on the server can be accessed, the operations of the Office are basically stopped. The Network Administrator immediately took out a tape of the backup document and tried to fix it. Her heart sank when she found that the tape was empty. She checked another backup tape and it was completely empty! She checked the Office logs and found that our colleagues changed the backup tape every day for two years, but the tape was put into the server that never installed the backup software. No one knows that the backup was faulty, this is because no one has ever checked it, but insisted on replacing the blank backup tape every day within two years. The incident caused heavy losses to the hospital. In fact, as long as any database administrator performs a simple backup check, this major problem can be avoided. In fact, they are doing this, every day.

Server Maintenance Error 5: Poor cable line engineering

A bank's network often goes wrong, so they specifically checked the distribution box, check found that many RJ-11 and RJ-12 plug into the RJ-45 socket. In addition, a toothpick is inserted into each socket, so that the cable line of the cloth is no wonder there will be problems. Many network problems are attributed to improper cable line connections. Therefore, it is best for a savvy manager to have a licensed, guaranteed, and trusted cable line contractor to rack cable lines.

Server Maintenance Error 6: Too Many device switches, internal issues

A professional sports group bought a famous server, but it had problems at work. The Network Administrator sends a request for help from the operating system vendor and hardware vendor. Later, it was discovered that the reseller who provided the "Famous-brand" server assigned the server a non-famous-brand memory, a non-famous-brand disk controller, and a non-famous-brand external disk drive, only because these components are cheaper. The hardware vendor and operating system vendor refuse to provide support because the server is confused by some non-famous-name component and its structure is not easy to be identified.

Server Maintenance Error 7: no authorization contract signed

An office spent a lot of cash last year purchasing servers. The system provides RAID 5 redundancy protection, dual power supply, and 24x7 support. A year later, the drive crashed. Ensure that 24 × 7 Support staff came, he called the hardware vendor, the vendor asked him what his contract number is, and the office did not sign an authorization contract before. "It doesn't matter," the vendor said. "They have two years before the license expires. I will change the drive for you within five or six days ."

However, the vendor's tolerance is far from enough. It is best to ensure that you have a full set of 24x7 Support and buy tags at an office supplies store, enter the authorized contract number and technical support phone number on each label and paste them on each machine.

Server Maintenance Error 8: no test environment is set up

A few years ago, a software development company installed a new workstation, which uses the fastest random access storage, the fastest hard drive and the fastest processor, it will serve as the chairman's new workstation. Shortly after the installation was completed, the Chairman accepted a request from his biggest partner company to use it to test the communication platform of the new man-made universe station. The result was a blue screen. When he was surprised to restart the computer, nothing was saved internally. After the system was rebuilt, it took him four days to get rid of the pile of Operation guides.

The Chairman of another company was wise enough to build a test network. Before the system upgrade, they will perform tests on the test network, identify errors again and again, and repeatedly set the network for Continuous testing until it is completely correct. Only when the test results are completely correct can the system be upgraded.

The Chairman of the first company no longer uses his server as a tester.

Server Maintenance Error 9: storage capacity planned out of weeks

When an art company bought a server five years ago, the server could support six 8G-byte RAID Array 5 drives. To save money, the company insisted on buying only four 4G-byte drives. The Network Administrator said that they would need more space soon, and the company eventually compromised and bought two more drivers, so it took up the matter. Three years later, they experienced serious space insufficiency. They even had to delete small files with only 50 K bytes. They urgently needed to expand the capacity. At that time, 8G-byte drives were no longer available and larger servers could not. A new extra subsystem that can solve the problem will require more money than the original server. In this way, they had to replace the server two years ahead of schedule. Therefore, a good storage capacity plan will save you money and even extend your system life.

Server Maintenance Error 10: incorrect operation is the biggest risk

In the afternoon, the power of the office suddenly broke down, and the nervous office manager thought it would damage both of their servers, so he took a quick action-he went over and turned off the servers. At home, he was proud of his rapid operations. But the next morning, when he returned to the office to open two servers, he found that there was nothing in it. In fact, when he pressed the server switch yesterday, the server was carrying out complex updates to key files. When he terminated the work of one server, it affected the storage of another server's key database. It took two days to repair the network.

This is the most unpredictable among all network protection issues. Therefore, the technical quality of network users must be improved.
