Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.

In view of the above, in a first aspect of the embodiments of the present invention, an embodiment of a method for monitoring a memory jpod is provided. Fig. 1 is a schematic diagram illustrating an embodiment of a method for monitoring a memory jpod according to the present invention. As shown in fig. 1, the embodiment of the present invention includes the following steps:

s1, reading the uploaded SAS addresses of the control panel and the hard disk backboard;

s2, scanning all SAS cards to obtain the SAS address of the SAS card, and judging whether the SAS address of the SAS card is consistent with the uploaded SAS address;

s3, in response to the SAS address of the SAS card being consistent with the uploaded SAS address, reading the corresponding Jbod identification code in the control panel; and

s4, establishing the association between the SAS card and the Jbod based on the identification code to form a topological link, and detecting whether the topological link is normal.

A bond is an important class of memory devices in the memory domain. JBOD (Just a Bunch Of Disks) is a storage device with multiple disk drives mounted on a backplane. Also commonly referred to as Span. Unlike RAID (redundant array of independent disks), JBOD has no front-end logic to manage the data distribution across the disks, but instead each disk is addressed individually, either as a separate storage resource, or based on a portion of the host software, or an adapter card for the RAID group.

The identification code of the Jbod is written into the control board. An identification code (e.g., SN) of a Jbod can be written to a Platform series field by Expander; the Fru (field replaceable unit) information of the Jbod can be written into the control board (e.g., CM board) of the Jbod through the BMC.

And reading the uploaded SAS addresses of the control panel and the hard disk backboard. When the system is powered on, SAS (serial attached small computer system interface) addresses of the control board and the plurality of hard disk backplanes can be read. The plurality of hard disk backboards are controlled by the control board, the number of the hard disk backboards is four in the embodiment, certainly, the number of the hard disk backboards is not limited, and in other embodiments, other numbers of hard disk backboards can be arranged as required. The configuration Page (e.g., Page10) stores the identification codes (SN) of the control board and the four hard disk backplanes, and the system can obtain the identification codes of the control board and the four hard disk backplanes in a query manner. The identification code may be uploaded through Page 10.

And scanning all the SAS cards to obtain the SAS addresses of the SAS cards, and judging whether the SAS addresses of the SAS cards are consistent with the uploaded SAS addresses. In some embodiments, said scanning all SAS cards to obtain SAS addresses of SAS cards comprises: and acquiring the SAS address of the port of the SAS card and the SAS address of the equipment linked with the port of the SAS card.

And in response to the SAS address of the existing SAS card is consistent with the uploaded SAS address, reading the identification code of the corresponding Jbod in the control board.

And establishing association between the SAS card and the Jbod based on the identification code to form a topological link, and detecting whether the topological link is normal. In some embodiments, said establishing an association of said SAS card with said Jbod to form a topological link based on said identification code comprises: establishing association between the identification code of the port of the SAS card and the identification code of the Jbod; and establishing association between the identification code of the Jbod and the identification code of the hard disk backboard. The SAS address of the SAS card is consistent with that uploaded by Page10, so that the port of the SAS card can read the Expander information in the Jbod information, and in this case, the SN (Serial Number, identification code) of the port of the SAS card is associated with the Serial Number of the connected Jbod; the Serial Number of the Jbod is associated with the Serial Number of the Expander in the hard disk backplane that the Jbod port can access. The topology link is formed based on the above association, for example, the OS (system) side may call the HBA-Expander-HDD to acquire the topology link through a tool. In some embodiments, further comprising: in response to the link anomaly, locating an anomaly based on the identification code.

The embodiment of the invention realizes the purpose of monitoring the Jbod state, the hard disk backboard state and the hard disk state by calling the expander parameter in-band to form a topological structure. And obtaining and calling related parameters at the OS end to achieve the mechanism of data protection of the storage Jbod. By the embodiment of the invention, the Jbod data can be stored safely, once the hard disk is in a state, the hard disk can be informed in time, and data dropping and data loss caused by non-human factors are reduced.

It should be particularly noted that, the steps in the embodiments of the method for monitoring a storage Jbod can be mutually intersected, replaced, added, and deleted, so that these methods for monitoring a storage Jbod with reasonable permutation and combination conversion also belong to the scope of the present invention, and the scope of the present invention should not be limited to the embodiments.

In view of the above object, according to a second aspect of the embodiments of the present invention, there is provided a system for monitoring a storage jpod, including: the first reading module is configured to read the uploaded SAS addresses of the control board and the hard disk backboard; the scanning module is configured to scan all SAS cards to obtain SAS addresses of the SAS cards and judge whether the SAS addresses of the SAS cards are consistent with the uploaded SAS addresses; the second reading module is configured to respond to the fact that the SAS address of the SAS card is consistent with the uploaded SAS address, and read the identification code of the corresponding Jbod in the control board; and the detection module is configured to establish association between the SAS card and the Jbod based on the identification code to form a topological link and detect whether the topological link is normal.

In view of the above object, a third aspect of the embodiments of the present invention provides a computer device, including: at least one processor; and a memory storing computer instructions executable on the processor, the instructions being executable by the processor to perform the steps of: s1, reading the uploaded SAS addresses of the control panel and the hard disk backboard; s2, scanning all SAS cards to obtain the SAS address of the SAS card, and judging whether the SAS address of the SAS card is consistent with the uploaded SAS address; s3, in response to the SAS address of the SAS card being consistent with the uploaded SAS address, reading the corresponding Jbod identification code in the control panel; and S4, establishing the association between the SAS card and the Jbod based on the identification code to form a topological link, and detecting whether the topological link is normal.
