Repair the tape library's tape cassette and the self-test fails
The tape cassette failure of the tape drive, tape library, and tape autoloader is one Our company has many years of maintenance experience for common and frequent faults. We will now make some classifications and summaries to facilitate customers’ reference in dealing with such faults
, 1. Common faults of tape drive cartridges
, Tape drive Since its inception, many technologies have emerged. Early tape drives have technologies, technologies, technologies, and other technologies. The reliability of these types of tape drives is different. However, in practice, it is found that the problem of tape cassette exists. There are various reasons, including mechanical and electronic. We focus on the emergency treatment of cassettes.
, . For technical tape drives, the probability of tape jamming is relatively high. There are two types of tape drives: magnetic tape drive and magnetic tape drive. Because the loading of this technical tape drive is more complicated and the loading mechanism has many sensors, Most of the time, the loading failure is caused by the poor usage environment and related sensor failure. The tape cannot go in or out. This situation cannot be handled by the user. If the tape is important, be sure to ask a professional to secure the tape. Remove it. Since the cost of this type of tape drive is not high, it is up to the user to decide whether to repair it or not.
, . technology tape drive, this type of tape drive uses linear technology, so the loading mechanism is relatively simple, and cassette failures rarely occur. Since a considerable part of its transmission mechanism is designed in the tape, the most common ones are currently found. The most common tape failure is caused by the aging of the transmission mechanism inside the tape. This situation can be solved by replacing it with a good tape.
, . Technology's tape drive. Before the advent of technology, tape drives were mid-to-high-end products and were widely used. Compared with technology and technology, they had the characteristics of fast speed and high reliability. So far, they have developed At this level, the most common failure of this type of tape drive is to pull off the tape drive's leader or the tape's leader after the tape is stuck. This is a fatal failure. So far, there is no good prevention method. Our company can save some of the leaders. A broken tape can be used to repair a tape drive with a broken leader. This type of tape drive cassette also requires maintenance by professional personnel. Users cannot disassemble the machine without authorization to avoid further expansion of the fault.
, . Technical tape drive, technical tape drive is the current mainstream product, the main manufacturers are,,, and, in addition, companies and companies produce half-height tape drive, technical tape drive through After more than ten years of development, the technology has become quite mature, but the problem of tape cassettes also occurs frequently. This type of tape drive is mainly used in large tape libraries, so once the cassette is stuck, it needs to be handled carefully, because the stuck tape may be backup data. Users must not dismantle the damaged parts without authorization. After being handled by professionals, most of them can be taken out intact to ensure the integrity of the data. Generally speaking, full-height tape drives are much more reliable than half-height tape drives. Stakes in half-height tape drives are mostly fatal, and the tapes will be shredded in most cases. In practice, it has been found that in most cases, jams in full-height tape drives can be resolved. Remove the tape intact. In order to reduce the occurrence of tape cassette failures, it is recommended that customers keep the tapes well and do not bump the tapes. Check whether the tape head is normal before using the machine. The tape drive must be unloaded correctly before powering off and shutting down. The tape drive does not have any technical specifications. Maintenance and refueling requirements are required, but the usage environment has requirements. It is recommended that users use the tape drive in a suitable environment.
, 2. Common tape cassette failures in automatic tape loaders
, . Cassette failures in automatic tape loaders can be divided into two parts, namely the driver, loader and transmission mechanism. The situation of the driver is the same as above. I won’t go into details anymore, but mainly talk about the situation of tape cassette in the loader and transmission mechanism. The representative types of this type of machine are / series and series. The machine structures of these two series are basically the same. The tape must be loaded correctly into the tape drive. , through the loader and transmission mechanism, cassette failures mainly occur in these two links. Loader damage and inaccurate positioning of the transmission mechanism are the main causes of the cassette. This failure is mainly due to the aging of the belt, the failure of related sensors, and mechanical It is caused by excessive wear, damage to the servo circuit, etc. There are corresponding fault codes that can be checked in the manuals of these two types of machines. They are not of great guidance to users because they do not have the experience and corresponding accessories to replace. I recommend calling a professional to take care of it.
, . For this type of loader or (the company calls this grade of machine also a loader), the cassette of this type of loader is mainly a problem between the robot arm and the library body. Comparison of the faults of the robot arm of this type of loader Many, because they are plastic gears. In practice, it has been found that broken gears often occur. Aging of the photoelectric sensor and failure of the control circuit may cause the tape to become stuck. Most of the manifestations are incorrect positioning and stuck in the library body. Damage to the slot may also cause Cassette.
, 3. Common faults of tape library cassettes
, There are many types of tape libraries, and cassette faults are various. It is very difficult to eliminate such faults caused by unstable and irregular work. The robot is The core component of the tape library is composed of mechanical, electronic, optical and other related components. The aging of any part and the failure of the sensor may cause a tape jam.
, . For these three types of tape libraries, the failure rates of the robots are different. The robots are relatively simple, while the failure rates are relatively low and complex. In particular, disassembly and assembly are difficult. Motors with grating sensors will malfunction after being used for a long time, and the stability of the photoelectric sensor will also deteriorate.
, . For /, / is a type of tape library, the failure of the manipulator cassette is mainly caused by the mechanical failure of the manipulator and the failure of the corresponding sensor.
, . For tape libraries of the series, the manipulator and the robotic arm of this type of tape library are together, and the reasons for tape cassette are more complicated. This is a medium-sized tape library, which is generally used in more important occasions and is currently widely used. , this kind of tape library manipulator has a high failure rate. It consists of a robotic arm, a manipulator and a scanner gun. The failure of any link may cause a tape jam.
, . For/, this type of tape library cassette failure phenomenon is different from the above situation. This type of tape library manipulator shaft is driven by a belt. In practice, it is found that the shaft often does not return to the position and the shaft does not return. When the tape is in place, the tape is often stuck between the manipulator and the slot. The installed capacity of this kind of machine is not very large, and it is difficult to disassemble and assemble the shaft. This type of tape library card failure is more complicated and requires experienced engineers to deal with it.
, . For large tape libraries, such as //'s cassette failure, our handling guidance is that the robot has a service life, and it must be replaced according to the working time to ensure backup reliability in important occasions. In practice We found that the biggest problem of this type of tape library is that the robot arm works unstable. Sometimes the tape gets stuck in the robot hand or is unreliable in loading. Sometimes it happens once a week or two, and the specific reason cannot be found. We have tested it through the replacement method. Most of the problems are It is caused by the aging of the manipulator. Since there are many optical cameras and optical sensors on the manipulator, these things have a lifespan and gradually age. It is recommended not to wait until they are completely damaged before replacing them.
