![]() LTO Tape Drive Cleaning Over time, all tape drives need to be cleaned with a dedicated cleaning tape. The average cleaning tape can be used up to 50 times before it is used up, and is considered as "expired." After the cleaning tape expires, the tape is not available and needs to be discarded. Clean tapes are considered consumer products and customers must provide these consumer products to keep tape drives running. There are two basic cleaning procedures that can be performed. The first, and most common, is called reactive drive cleaning. After the drive has performed a predetermined number of read/write hours, or if the calendar-based plan is cleared in hours, days, or weeks, the active drive is cleared. One thing to consider is that the HP-branded IBM brand LTO driver does not have this same limitation. The LTO driver needs to write active drive cleanup at least every 100 hours. This is because HP-branded LTO drives disable the passive release of clean tape alerts when performing write-only operations. Tape alert 20 is an "immediate cleanup" event, meaning it needs to be cleaned immediately. Tape alarm 21 is a "cleanup cycle" event, which means that the tape drive may receive an "Expired Clean Media" event while the tape is still loading an expired cleaning tape into the drive. The library cleanup process can be managed automatically by the library or application software. This is often referred to as "library management" or "application management" drive cleanup. The following are two types of cleaning management and their professionalism and services. Library Management Drive Cleaning When using library-managed tape drive cleaning, the tape library performs tape drive cleaning processes and manages the storage of cleaning tapes. According to the defined cleaning plan, the library automatically moves the cleaning tape in and out of the drive as needed. The storage element must be defined as a "cleaning program" that cleans tapes in the tape library. With the library management cleanup feature enabled, most cleanup processes are performed in a "reactive" manner. Some (but not all) libraries can actively clear the overall plan based on the number of hours read/written by the drive. The main challenge when using tape library Managed Drive Cleaning is that you must import and export cleaning cartridges as cleaning media. If you do not introduce the cleaning tape as a cleaning media, the library will not treat it as a cleaning tape. If a cleaning process is required, the cleaning belt cannot be used. We generally recommend using library management cleanup only if the application cannot manage the drive cleanup process. Application Management Drive Cleanup It is highly recommended to use application software to manage cleaning as it can define more precise cleaning schedules. Another advantage is cleaning the tape. The cleaning tape is usually identified by its media bar code label number. As long as the cleaning tape is in the tape library, the application software can use the tape according to the needs of the cleaning process. At a minimum, reactive drive cleaning procedures (libraries or application management) should be configured to properly clean the drive as needed. If necessary, you can manually install the cleaning cartridge into the drive, but you can manually intervene through the library GUI or application software. Read More: More Blogs:
