During the upgrade process, hardware failures, hard drive failures, or system failures on the storage device can all cause the upgrade to fail, leading to a BIOS version downgrade. If the IP address of the storage device's management controller is found to be 0.0.0.0 during this downgrade, the rollback will fail, the management controller will enter service mode, and services will be interrupted, preventing normal operation.

[0014] If the second operating states of the two management controllers are the same, return to the step of obtaining the second operating state of each management controller every first preset time interval;

[0015] If the second operating states of the two management controllers are different, the IP information of the management controller whose operating state is the main operating state is obtained.

[0016] Optionally, the method further includes:

[0017] If the operating states of the two management controllers remain the same within a second preset time period starting from the first detection start point, then each management controller is restarted, and the step of obtaining the operating state of each management controller is returned.

[0018] Optionally, if all address bits in the IP information are 0, then the pre-defined retry mechanism for the management controller is activated, and the step of obtaining the IP information of the management controller whose running state is the main running state is returned includes:

[0019] If all address bits in the first IP information are 0, record the second start time corresponding to the first IP information of the management controller whose main running state is obtained.

[0035] The embodiments of the present invention include the following advantages: when a BIOS downgrade is detected, the operating status of each management controller is obtained. If the operating status of two management controllers is different, the IP information of the management controller whose operating status is the primary operating status is obtained.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] Reference Figure 1This diagram illustrates a flowchart of a BIOS downgrade processing method provided in an embodiment of the present invention, applied to a storage device. The storage device includes a BIOS system and two management controllers. Each management controller operates in either a master or slave state within the storage device. Specifically, the method may include the following steps:

[0044] Step 101: If a BIOS downgrade is detected, obtain the operating status of each management controller;

[0045] Storage devices are used to store information, typically by digitizing the information and then storing it using media such as electricity, magnetism, or optics. In this embodiment of the invention, the storage device can be a storage server, and a BIOS runs within it. The BIOS is a set of programs embedded in a ROM (Read-Only Memory) chip on the computer's motherboard. It stores the computer's most important basic input / output programs, power-on self-test (POST) programs, and system startup programs. It can read and write specific system settings. Its main function is to provide the lowest-level, most direct hardware settings and control for the computer. BIOS upgrades are essential for ensuring more stable operation of storage devices. BIOS upgrades have the following benefits: supporting the latest hardware, optimizing older hardware, obtaining the latest security or vulnerability patches, changing some options within the BIOS, and supporting new features. However, during an upgrade, hardware failures, hard drive failures, system failures, etc., can all cause the BIOS upgrade to fail, resulting in a downgrade to the previous version.

[0046] The storage device also includes two management controllers (CMCs, Central Message Controllers), which manage and control the storage device. The storage device supports dual management controller redundancy. Each management controller can operate as either a master or slave. Under normal operating conditions, one management controller operates as the master, managing and controlling the storage device, while the other operates as a slave. If the master management controller fails, the slave controller takes over as the master, ensuring the continued operation of the storage device.

[0047] If a BIOS degradation of the storage device is detected, the operating status of each management controller can be obtained. If the operating status of two management controllers is the same, either both in master mode or both in slave mode, then the status of the management controllers is abnormal and degradation cannot continue. Degradation can only continue if the operating status of the two management controllers is different, that is, one of the two management controllers is in master mode and the other is in slave mode.

[0048] Step 102: If the two management controllers are in different operating states, then obtain the IP information of the management controller whose operating state is the dominant operating state.

[0049] The IP information of the management controller contains the IP address of the corresponding management controller, which includes multiple address bits. If the two management controllers are in different operating states, it can be determined that both management controllers are operating normally in the storage device. In this case, the IP information of the management controller with the dominant operating state will be retrieved.

[0050] Step 103: If all address bits in the IP information are 0, then start the pre-set retry mechanism for the management controller and return to the step of obtaining the IP information of the management controller whose running state is the main running state.

[0051] If all address bits in the IP information of the management controller in the primary running state are 0, i.e., the IP of the management controller in the primary running state is 0.0.0.0, it can be determined that the IP of the management controller in the primary running state is abnormal. During BIOS downgrade, if the IP of the management controller in the primary running state is abnormal, the management controller enters service mode, the service is interrupted, and the BIOS cannot operate normally. To avoid this situation, this embodiment of the invention introduces a retry mechanism. When an IP abnormality of the management controller in the primary running state is detected, a pre-set retry mechanism for the management controller is initiated, returning to the step of obtaining the IP information of the management controller in the primary running state, until the IP in the IP information is a valid IP.

[0052] Step 104: If the address bits in the IP information are not all 0, then downgrade the BIOS according to the IP information.

[0053] If the address bits in the IP information of the management controller in the primary running state are not all 0, that is, if the IP of the management controller in the primary running state is not 0.0.0.0, then the IP of the management controller in the primary running state is a valid IP, and the storage device will downgrade the BIOS based on the IP information of the management controller in the primary running state.

[0054] In this embodiment of the invention, when a BIOS downgrade is detected, the operating status of each management controller is obtained. If the operating statuses of two management controllers are different, the IP information of the management controller whose operating status is the primary operating status is obtained. If all address bits in the IP information are 0, a pre-defined retry mechanism for the management controller is initiated, and the process returns to obtaining the IP information of the management controller whose operating status is the primary operating status. If not all address bits in the IP information are 0, the BIOS is downgraded based on the IP information. This achieves the goal of introducing a retry mechanism during BIOS downgrade, initiating a retry mechanism when the IP of the management controller is abnormal, and re-obtaining the IP of the management controller, ensuring that a valid IP address of the management controller is obtained during BIOS downgrade, and preventing BIOS downgrade failure of the storage device.

[0055] Reference Figure 2 This diagram illustrates a flowchart of another BIOS downgrade processing method provided in an embodiment of the present invention, applied to a storage device. The storage device includes a BIOS system and two management controllers. Each management controller operates in either a master or slave state within the storage device. Specifically, the method may include the following steps:

[0056] Step 201: If a BIOS downgrade is detected, obtain the operating status of each management controller;

[0057] If a BIOS degradation of the storage device is detected, the operating status of each management controller can be obtained. If the operating status of two management controllers is the same, either both in master mode or both in slave mode, then the status of the management controllers is abnormal and degradation cannot continue. Degradation can only continue if the operating status of the two management controllers is different, that is, one of the two management controllers is in master mode and the other is in slave mode.

[0058] In an optional embodiment of the present invention, after obtaining the operating status of each management controller when a BIOS downgrade is detected, the method further includes:

[0059] Step S1: When the first operating states of the two management controllers are the same, record the first start time corresponding to the first operating state of each management controller.

[0060] If the first operating states of the two management controllers are the same, that is, both of the first operating states of the two management controllers are the master operating state or the slave operating state, the first start time corresponding to the first operating state of each management controller can be recorded and obtained.

[0061] Step S2: Taking the first start time as the first detection starting point, the second operating state corresponding to each management controller is obtained every first preset time interval;

[0062] After recording the first start time corresponding to the first operating state of each management controller, the second operating state corresponding to each management controller is obtained every first preset time interval, using the first start time as the first detection starting point. In one example, since the time for the management controller to switch operating states is 30 seconds, the first preset time interval can be set to 30 seconds.

[0063] Step S3: If the second operating states of the two management controllers are the same, return to the step of obtaining the second operating state of each management controller every first preset time interval;

[0064] If the second operating states of the two management controllers are found to be the same, the step of obtaining the second operating state of each management controller every first preset time interval is returned. That is, when the operating states of the two management controllers are the same, the operating state of each management controller is obtained every 30 seconds from the first start time corresponding to the first operating state of each management controller.

[0065] Step S4: If the second operating states of the two management controllers are different, then obtain the IP information of the management controller whose operating state is the main operating state.

[0066] If the second operating states of the two management controllers are detected to be different (i.e., one is in master operating state and the other is in slave operating state), then the IP information of the management controller in the master operating state is obtained. By introducing a retry mechanism, the IP information of the management controller is only obtained if the management controller in the storage device is operating normally.

[0067] In an optional embodiment of the present invention, the method further includes:

[0068] If the operating states of the two management controllers remain the same within a second preset time period starting from the first detection start point, then each management controller is restarted, and the step of obtaining the operating state of each management controller is returned.

[0069] If, within a second preset time period starting from the first detection point, the operating states of the two management controllers remain identical, then the two management controllers can be restarted, and the process can return to the step of obtaining the operating states of each management controller. In one example, the second preset time period can be set to 10 minutes to ensure that the management controllers have sufficient time to complete the startup process.

[0070] Step 202: If the two management controllers are in different operating states, then obtain the IP information of the management controller whose operating state is the dominant operating state.

[0071] The IP information of the management controller contains the IP address of the corresponding management controller, which includes multiple address bits. If the two management controllers are in different operating states, it can be determined that both management controllers are operating normally in the storage device. In this case, the IP information of the management controller with the dominant operating state will be retrieved.

[0072] Step 203: If all address bits in the first IP information are 0, record the second start time corresponding to the first IP information of the management controller whose running state is the main running state.

[0073] If all address bits in the first IP information of the management controller in the main running state are 0, indicating an IP anomaly in the management controller in the main running state, the second start time corresponding to the first IP information of the management controller in the main running state can be recorded.

[0074] Step 204: Using the second start time as the second detection starting point, acquire the second IP information of the management controller whose main operating state is the operating state every first preset time interval;

[0075] After recording the second start time corresponding to the first IP information of the management controller whose running status is primarily running, the second IP information of the management controller whose running status is primarily running is obtained every first preset time interval, using the second start time as the second detection starting point. In one example, the first preset time interval can be set to 30 seconds.

[0076] Step 205: If all address bits in the second IP information of the management controller whose operating state is the main operating state are 0, return to the step of obtaining the second IP information of the management controller whose operating state is the main operating state every first preset time interval.

[0077] If all address bits in the second IP information of the management controller in the main running state are detected to be 0, then the step of obtaining the second IP information of the management controller in the main running state every first preset time interval is returned. That is, when all address bits in the IP information of the management controller in the main running state are 0, starting from the second start time corresponding to the first IP information of the management controller in the main running state, the IP information of the management controller in the main running state is obtained every 30 seconds.

[0078] In an optional embodiment of the present invention, the management controller includes a network chip, and the method further includes:

[0079] If the address bits in the IP information remain 0 for a second preset time period starting from the second detection start point, the network chip is reset, and the process returns to the step of obtaining the IP information of the management controller whose operating state is the main operating state.

[0080] If, within a second preset time period starting from the first detection point, the operating states of the two management controllers remain identical, the network chip in the dominant operating state can be reset by executing the commands `ethtool -s eth0 autoneg off` and `ethtool -s eth0 autonegon`, returning to the step of obtaining the IP information of the management controller in the dominant operating state. In one example, the second preset time period can be set to 10 minutes to ensure the management controller has sufficient time to complete startup when resetting the network chip.

[0081] Step 206: If the address bits in the IP information are not all 0, then downgrade the BIOS according to the IP information.

[0082] If the address bits in the IP information of the primary running controller are not all 0 (i.e., the IP address of the primary running controller is not 0.0.0.0), then the primary running controller's IP address is considered valid. The storage device will then downgrade the BIOS based on this IP address. By introducing a retry mechanism, BIOS downgrading is only performed when the primary running controller's IP address is valid. This prevents the storage device's management controller from failing to downgrade if its IP address is abnormal and it enters service mode.

[0083] In an optional embodiment of the present invention, the storage device includes a BIOS downgrade script, and the step of downgrading the BIOS based on the IP information includes:

[0084] Based on the IP information, the BIOS is automatically downgraded by calling the BIOS downgrade script.

[0085] The storage device stores the BIOS downgrade script required for BIOS downgrade. If the address bits in the IP information of the management controller in the primary running state are not all 0, that is, the IP of the management controller in the primary running state is valid, the BIOS downgrade script can be called according to the IP of the management controller in the primary running state to automatically downgrade the BIOS.

[0086] In this embodiment of the invention, when a BIOS downgrade is detected, the operating status of each management controller is obtained. If the operating statuses of the two management controllers are different, the IP information of the management controller whose operating status is the primary operating status is obtained. If all address bits in the first IP information are 0, the second start time corresponding to the first IP information of the management controller whose operating status is the primary operating status is recorded. Using the second start time as the second detection start point, the second IP information of the management controller whose operating status is the primary operating status is obtained every first preset time interval. If all address bits in the second IP information of the management controller whose operating status is the primary operating status are 0, the step of obtaining the second IP information of the management controller whose operating status is the primary operating status is returned every first preset time interval. If the address bits in the IP information are not all 0, the BIOS is downgraded according to the IP information. This achieves the introduction of a retry mechanism during BIOS downgrade. When the operating status of the management controller is abnormal or the IP is abnormal, the retry mechanism is started to re-obtain the operating status and IP of the management controller, thereby ensuring that a valid IP address of the management controller is obtained during BIOS downgrade and preventing BIOS downgrade failure of the storage device.

[0087] Reference Figure 3 This is a flowchart of a BIOS downgrade processing method provided in an embodiment of the present invention;

[0088] Step 301; Obtain the operating status of each management controller;

[0089] Step 302: Determine whether the operating states of the two management controllers are the same. If not, proceed to step 303; if yes, proceed to step 304.

[0090] Step 303: Obtain the IP information of the management controller whose running status is the main running status;

[0091] Step 304, wait 30 seconds;

[0092] Step 305: Record the first start time corresponding to the first running state of each management controller, and determine whether more than 10 minutes have passed since the first start time; if not, return to step 301; if yes, proceed to step 306.

[0093] Step 306: Restart all management controllers and return to step 301;

[0094] Step 307: Determine if all address bits in the IP information are 0; if not, proceed to step 308; if yes, proceed to step 309.

[0095] Step 308: Downgrade the BIOS based on the IP information;

[0096] Step 309, wait 30 seconds;

[0097] Step 3010: Record the second start time corresponding to the first IP information of the management controller whose main running state is obtained, and determine whether more than 10 minutes have passed since the second start time; if not, return to step 303; if yes, execute step 3011.

[0098] Step 3011: Reset the network chip and return to step 303.
