[0004] According to the work of the current named inventor, it is found that the existing processing methods are manually edited by the operation and maintenance personnel: first manually editing the volume, it is necessary to name hundreds of volume names, and the editing and naming used by each operation and maintenance personnel The methods may be different, which is not easy to maintain and search. Then, according to the manually edited volume name, find the corresponding serial number or key under the ASM architecture through commands, make one-to-one correspondence, and write it into the configuration file multipath.conf , and then validate the file
The current method has shortcomings such as low efficiency, time-consuming, error-prone, and difficult to troubleshoot

Embodiment Construction
[0025] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.
[0026] The invention proposes a method for automatically dividing disks based on the multipath.conf configuration file according to the principle of the ASM configuration volume and without modifying the ASM source code, and realizes the automatic generation of the multipath.conf through a script tool and makes it in the ASM Effective under the structure. refer to figure 1 , the method includes the following steps:
[0027] Step S1, creating a script.
[0028] Use the script editing tool to create and edit the script. The content of the script includes the following functions:
[0029] 1) Name the volume to ensure that the naming is not repeated;
[0030] 2) Allocate the capacity of the storage node to the space division of each volume;
[0031] 3) Search for name-key, name is the volume name, and key is the identifier corresponding to the...

The invention provides a method for automatically dividing ASM volumes, and belongs to the technical field of databases. According to the method, automatic volume division is carried out on the basisof a multipath. conf configuration file. Automatic generation of multipath. conf is realized through a script tool and the multipath. conf is enabled to take effect under an ASM architecture, the defects in the prior art that volume naming and dividing efficiency is low, time is consumed, errors are prone to occurring, and troubleshooting is difficult are overcome, the working efficiency of operation and maintenance personnel is greatly improved, the working time of the operation and maintenance personnel is shortened, the standardized operation level of the operation and maintenance personnelis improved, and the fault can be quickly responded and located when the system breaks down.
Description
technical field [0001] The invention relates to the technical field of databases, in particular to a method for automatically dividing ASM volumes. Background technique [0002] The full name of ASM is Automated Storage Management, commonly known as Automatic Storage Management System, which is a new feature introduced from Oracle Database 10g version. ASM is managed by the ASM CMD tool. It can bypass the storage management of the underlying operating system and provide services such as file system, logical volume manager, and software RAID (disk array) in a platform-independent manner. Affects direct processing of data on disk, which is more efficient than the operating system layer. [0003] Under the ASM architecture, each ASM instance (computing node) will be applied to the disk group diskgroup formed by any combination of disks under its architecture. Each storage node can have multiple disks, and each disk is divided into several volumes. . In the original volume na...
