In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following explains key terms appearing in the present application.
FIG. 1 is a schematic flow chart diagram of a method of one embodiment of the present application. The execution subject in fig. 1 may be a hard disk failure monitoring and detecting device.
As shown in fig. 1, the method 100 includes:
In order to facilitate understanding of the present invention, the hard disk failure monitoring and detecting method provided by the present invention is further described below with reference to the principle of the hard disk failure monitoring and detecting method of the present invention and the process of monitoring and detecting hard disk failures in the embodiments.
Optionally, as an embodiment of the present application, the generating a topology structure of the virtual layer according to the interface information and the hard disk information includes:
acquiring a slot number, a port number and an identification sequence of a hard disk mounted by a disk array controller;
and generating a topological structure of the virtual layer according to the slot number, the port number and the identification sequence.
Optionally, as an embodiment of the present application, the determining a hard disk fault according to a fault determination condition includes:
judging whether the hard disk information acquired by polling comprises a fault judgment condition:
if yes, judging that the hard disk fails and lightening a corresponding fault identification lamp;
and if not, judging that the hard disk is normal.
Optionally, as an embodiment of the present application, the method further includes:
collecting PFA information of the hard disk drive through a Log Sense command of a Log page;
and predicting the hard disk fault according to the PFA information.
Specifically, the hard disk fault monitoring and detecting method includes:
s1, creating a virtual layer in the firmware of the disk array controller.
And S2, generating the topological structure of the virtual layer according to the interface information and the hard disk information.
A typical SAS card is pass-through, i.e., simply presents the disk to the system completely, and does nothing on its own. After the virtual layer is added, the SAS card may record information of the disks mounted under the card, such as port number, slot number, order, etc., which may form a card-to-disk topology. When the topology structure changes, it is necessary to determine whether a failure occurs.
And S3, setting a fault judgment condition.
The set failure determination conditions are as follows:
the drive is not ready; a driver startup failure; mode-sense data cannot be acquired; drive capacity is not available; driver information cannot be acquired through a SCSI inquiry command; the link is unstable for too long; repeat PHY up/down; the device reset operation fails.
And S4, monitoring the topological structure and judging whether the topological structure is changed.
S5, if the topological structure change is monitored in the step S4, whether the hard disk information acquired by firmware polling meets one or more fault determination conditions in the step S3 is further determined, if so, the hard disk fault is determined and an LED lamp on a hard disk backboard is lightened through an SGPIO signal, and the general firmware sets a Locate bit (ODn.1) to 0 and an ERROR bit (ODn.2) to 1 according to an SFF-8489 protocol; and if the fault judgment condition is not met, removing the hard disk fault.
If the topology is not changed as monitored in step S4, the topology monitoring is continued.
S6, collecting PFA information of the hard disk drive through a Log Sense command of the Log page and predicting the hard disk fault according to the PFA information.
Predictive Failure Analysis (PFA) of a hard disk is defined by the T10/T13 specification.
Firstly, when a controller is started or a hard disk is hot plugged, FW of the SAS card reads S.M.A.R.T. information of the hard disk in the background and judges whether the hard disk supports PFA function.
Subsequently, when the hard disk supports PFA functionality, a task to periodically detect PFA is added to the background task, typically for 2-5 minutes, and the controller firmware issues a Log Sense command to Log the page to retrieve PFA information from the drive.
Finally, when a driver with predictive alarm (PFA) is detected, the SAS card lights the LED lights on the hard disk backplane via the SGPIO signal, and the ERROR lights flash with the predictive failure set to 2HZ, typically by firmware following the SFF-8489 protocol.
