Description of the Invention: [Technical Field] The present invention relates to a disk array profile processing method, and more particularly to a disk array profile updating method. Go, and special [Prior Art] With the increasing popularity of computers, the number of people stored in computers is growing. Therefore, the computer Weishang has developed a storage medium that is constantly accommodating with capacity. However, generally there is a large capacity to store a larger hard disk, and the transmission rate is limited by the access rate of the read head itself = the medium, such as the bus transfer rate, thus causing such a storage medium to be connected The bottleneck in speed. In addition, such storage media generally do not have the transmission of the bedding material. Therefore, when the storage medium is damaged, the data stored by it is also functioned. Therefore, a disk array has been developed (Redundant Array μ has a shell and another.

The simulated logical hard disk has a faster data rate and j u fault tolerance. Thousands have the disk array of several physical hard disks of the array of disks before accessing the logical hard disk simulated by the disk array. (4) The mformation sector (RIS) obtains the disk array setting ^ as bytes. Then, you can reduce and access the logical hard disk of __ according to the disk array settings stored on Cong. When the boot self_(PGW(4)n Sdf Test, p〇ST) is executed, the memory space available to the system is small (approximately 1MB). Therefore, when the boot self-detection detects the disk array, only the important block of the disk array setting 201037509 is created as _(10) (its bytes) to initialize and detect the state of the magnetic burn of 670 columns. There is a change (if there is 'in the detection of the disk array is removed according to the current state of the disk array update (four). In the self-made to complete the disk array detection 彳 first disk array settings 完成 and after the completion of the detection of the mini RIS comparison, := Whether to update the magnetic column configuration file according to the coffee. “ Ο When it is time, it needs to be configured separately - the block memory space is stored in the original = slot, so it is easy to cause insufficient memory space. In addition, even if the disk array is set to U In some of the fields, it is still necessary to write all the updated disk array profiles back to the disk array, which wastes a lot of data transmission and time taken. ' SUMMARY OF THE INVENTION Therefore, one of the objects of the present invention is Providing a disk array profile update method for "after booting self-detection to complete detection of a disk array", dividing the original disk array profile into several blocks, and dividing each zone One by one

Only on each block, when the pad corresponding to the mini RIS is updated, the above block is updated according to the mini RIS and written back to the disk array. According to an embodiment of the invention, a disk array profile updating method includes the steps of: capturing a mini profile from one of the original profiles of the disk array when a boot self-detection begins to detect a disk array. Initializes the disk array based on the mini profile and detects the current state of one of the disk arrays. The mini profile is updated based on the current state of the disk array. The mini profile set after updating 201037509 is compared with the original blocks of the original profile to determine whether the original profile has at least one update block to be updated. When at least one update block needs to be updated in the original configuration file, at least one update block is updated according to the updated file. Only the updated at least one update block is written back to the disk array' to update the original profile of the disk array. [Embodiment] Please refer to FIG. 1 , which is a flowchart of a method for updating a Redundant Array of Inexpensive Disks ( RAID ) profile according to an embodiment of the invention. The disk array configuration file updating method is used to divide the original disk array configuration file into several blocks after the power-on self test (POST) completes the detection of the disk array, and each block is changed one by one. Align with the mini RIS (RAID Inf〇rmati〇n Sector) after the completion of the test. Where 'only on each block, when the field corresponding to ris is updated, the above block is updated according to mini RIS and written back to the disk array. The disk array profile update method 10 includes the following steps: 撷 When detecting a disk drop-down (step 〇1〇) after a boot self-test starts, a mini profile is retrieved from one of the original profiles of the disk array ( Step 120). Among them, the original setting file is stored in the RIS' of several physical hard disks of the disk array, and the mini setting system is applied in the format of mjni ris. In step 130, the disk array is initialized based on the mini profile and the current state of one of the disk arrays is detected, such as whether a physical hard disk is added to the disk array or removed from the disk array. Next, in step 14A, the mini setting slot is updated according to the current state of the disk array. In step 150, the original partition of the original profile is obtained from the 201037509, and the size of each original block can be determined according to the actual demand, because the actual disk array is used. , write single enemies as block (512 bytes), so you can set the original size to 512 bytes of the original block. horse

The 'step 16G' is determined by comparing the obtained update block with the updated mini profile. In the acquired /, start block, the updated block corresponding to the mini setting slot has a more = original decision to obtain the original block as the updated block to be updated. Then, in step 170, when the original block obtained is the required update block, the original block is updated according to the updated mini profile, and the updated original block is written back to the original profile. In step 18, a current detection code is generated based on the updated original block and a temporary error detection code. However, when the obtained original block does not need to be updated, the current error detection code is generated according to the obtained original block and the temporary error detection code (step 190). Wherein, when the disk array profile update method 1 is started, the temporary storage error code system is preset to be null (Null). In addition, the current debt error codes in steps 180 and 190 can be generated by checksum or other error detection code generation. Next, the current error detection code is the temporary error detection code (step 2〇〇), and it is judged whether the obtained original block is the last block in the original configuration file (step 210). When the last block in the original block non-original profile is obtained, the next original block in the original profile is obtained (step 150). In this way, the original blocks to be updated in the original configuration file of the disk array can be updated one by one by step 15 〇 to step 210, and the error detection code of the original configuration file after the update of 201037509 is generated one by one. However, when the original block obtained is the last block in the original profile, the temporary error detection code is written back to the original profile of the disk array (step 220), as the debug of the updated original profile. code. In this way, the updated array can be used to access the disk array. It will be apparent from the above-described embodiments of the present invention that the application of the present invention has the following advantages. Since only one of the original profiles is compared with the mini-set building at a time, it is only necessary to configure the memory size of one block as the comparison 0. As a result, there is no memory space shortage when the boot self-detection detects the disk array. In addition, the prior art updates the original profile to the disk array after the original profile is updated. However, the application of the present invention only needs to update and write the above-mentioned block back to the original profile when the field corresponding to the mini profile is updated in the block of the original profile, thereby saving data transmission and access time. . In addition, the error detection code of the updated original profile is generated as each block is aligned. In other words, it is not necessary to recalculate the entire newer original profile after the original profile update is completed to generate an error detection code, thereby saving time for recalculation to generate an error detection code. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and the present invention can be modified and modified without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
