Problems solved by technology

However, when the HBA card is directly connected to the hard disk in JBOD mode, there has been a situation where the disk letter and the physical Slot number in the Linux system do not correspond. This problem will lead to customer data storage errors and the consequences of abnormal overwriting of original data
If it is serious, it will bring huge losses to customers

Embodiment

[0015] The method for real-time monitoring of the sequence of hard disks in JBOD mode described in this embodiment is a method for real-time monitoring of the sequence of hard disks in JBOD mode on a storage server. The principle of this monitoring method is to record the hard disk sequence and drive letter during each restart (or power on and off) of the server under the Linux operating system, first generate a standard hard disk SN list, and compare the data obtained later with the standard record; , and save the comparison results, when the data comparison is abnormal, an alarm will be given; as attached figure 1 shown.

Abstract

The invention discloses a hard disk sequence marshalling method based on a real-time JBOD monitoring mode. An order and a disk label of a hard disk are recorded through a server under the Linux operation system during process of each reboot (or startup and shutdown). A standard hard disk SN list is generated, so that obtained post processed data is compared with a standard hard disk SN list record, and the comparing result is saved. An alert is conducted when abnormality occurs during the data comparison. According to the method, besides the disk label sorting function of the hard disk can be monitored under a server system, a stable power supplying effect for a verification system can be achieved during the testing. The testing method has the advantages that the operation is simple, the utility range is wide, the portability is good, the practicality is high, and the stability of the server is effectively guaranteed. The testing method is an effective method for testing the quality of a product.

Description

technical field [0001] The invention relates to computer technology, in particular to a method for real-time monitoring of the arrangement sequence of hard disks in JBOD mode. Background technique [0002] JBOD is an important type of storage device in the storage field. JBOD (Just a Bunch Of Disks, disk cluster) is a storage device with multiple disk drives installed on a chassis. Unlike RAID arrays, JBODs have no front-end logic to manage the distribution of data across the disks. Instead, each disk is individually addressed as a separate storage resource, either based on part of the host software, or an adapter card in the RAID group. [0003] Storage servers have a little extra storage, and possibly a lot of storage. A multi-purpose server usually has less than five internal disks, but a storage server will have at least six internal disks, and most of the time it will reach 12 to 24 internal disks. In addition to the extra disks, storage servers come with a host of s...
