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 object, a first aspect of the embodiments of the present invention provides an embodiment of a method for upgrading firmware of a storage device. Fig. 2 is a schematic diagram illustrating an embodiment of a method for upgrading firmware of a storage device according to the present invention. As shown in fig. 2, an embodiment of the present invention includes the following steps performed at the expander:
s1, acquiring a compression package obtained by compressing the upgrade file according to the compression algorithm of the system;
s2, starting the decompression of the compressed packet according to the compression algorithm and simultaneously checking;
s3, responding to the verification, and further decompressing to obtain an upgrade file; and
and S4, flashing the flash memory based on the upgrade file to upgrade the firmware of the storage device.
In this embodiment, during the routine maintenance of the storage device, a user or a customer service staff may manually import the compressed upgrade file into the system through a network, a usb disk, or the like, or during the installation of the entire storage system, the system software may package the firmware binary upgrade file of the corresponding version into a system software package, and automatically start the upgrade process during the installation.
The system directly sends the compressed binary upgrade file to the expander, and in the process, the system does not provide data service due to the fact that a service link is occupied, so that the compression algorithm of the system is consistent with that of the expander, and the expander can decompress normally. By system compression, the compressed packet is transmitted to the expander, and the process of transmitting files can be reduced from three to five minutes to about one minute.
Decompressing the compressed packet in the expander for firmware upgrade, verifying the compressed packet based on a verification mechanism of a compression algorithm while starting decompressing the compressed packet, further decompressing to obtain an upgrade file in response to the verification passing, and flashing the flash memory by the expander based on the upgrade file to finish the upgrade of the firmware of the storage device. And the time of data transmission in the upgrading process is shortened, and whether the transmission of the compression packet is successful or not is judged according to whether the decompression is successful or not.
When the compressed packet has error codes in the transmission process, the decompression process can directly prompt that the decompression fails, so that whether the transmission of the upgrade file is correct can be judged by judging whether the expander successfully decompresses the compressed packet. The successful transmission can be confirmed after the decompression is successful, the expander is not required to transmit the received check code back to the system for verification, and only the decompression successful state needs to be replied, so that the time for write-back verification can be saved.
In some embodiments of the invention, further comprising: in response to the failure of the verification, sending a decompression failure prompt to the system processor through the expander; the system processor decompresses the compressed packet according to the compression algorithm; and responding to the failure of the system processor in decompressing the compressed packet, sending out a compressed packet invalidity prompt, and canceling the firmware upgrading. The compression algorithm has file check rules, such as parity check, CRC check, LRC check, Gray code check, and sum check, and XOR check. If the expansion device fails to decompress, the system decompresses the compressed file by itself, if the system is successfully decompressed, the system indicates that the compressed packet is not upgraded, and the expansion device is issued again to repeat the process; if the system fails to decompress, the compression packet is indicated to be wrong, the upgrading process is cancelled, and a prompt is sent.
In some embodiments of the invention, further comprising: in response to the system processor successfully decompressing the compressed packet, resending the compressed packet to the expander; the compressed packets are received by the expander and decompressed and upgraded again. The compression algorithm of the system is consistent with that of the expander, such as a tar compression algorithm commonly used in a Linux system, in an actual test, the size of the compressed firmware is about one fourth of that before compression, and the sizes of the upgrade files of different modules are slightly different.
In some embodiments of the invention, further comprising: resetting and restarting the firmware of the storage equipment to finish upgrading; and displaying the upgrading state on the display terminal. And after the expander successfully decompresses the compression packet, obtaining a binary file of the upgraded firmware, flashing the corresponding flash memory, and resetting and restarting the firmware of the storage device after the expander successfully decompresses the compression packet to finish upgrading. This process does not require the occupation of traffic links and therefore the data services of the storage device are not terminated.
In some embodiments of the invention, the firmware of the storage device includes an expander, a complex programmable logic device, and a device power supply unit. In the storage device, besides the system software running in the CPU, the storage device also has a plurality of modules managed by intelligent chips, and logically controlled by a burned firmware program. The modules needing firmware in the storage device comprise an expander for providing functions of case information query, temperature and voltage monitoring, fan speed regulation and the like, a CPLD for controlling power-on and power-off management and signal monitoring, and a device power Supply PSU (Power Supply Unit) for providing a device power Supply function. These above firmware often require occasional update updates due to the need to address known bugs or added functionality.
Fig. 3 is a flowchart illustrating an embodiment of a method for upgrading firmware of a storage device according to the present invention. As shown in fig. 3, the embodiment of the present invention includes the following steps:
after starting, the system sends the compression packet of the upgrade file to the expander, the expander decompresses the upgrade packet, and judges whether the decompression is successful: and if the decompression is successful, the expander writes the specified flash memory and restarts the corresponding chip, and the process is ended. If the decompression fails, the system decompresses the compressed packet, the system successfully decompresses and then transmits the compressed packet of the upgrade file to the expander for decompression again, and the system cancels the upgrade if the decompression fails, namely the default compressed packet is wrong.
It should be particularly noted that, the steps in the embodiments of the method for upgrading the firmware of the storage device may be mutually intersected, replaced, added, or deleted, and therefore, these methods for upgrading the firmware of the storage device, which are transformed by reasonable permutation and combination, should also belong to the scope of the present invention, and should not limit the scope of the present invention to the embodiments.

In some embodiments of the invention, further comprising: in response to the failure of the verification, the expander sends a decompression failure prompt to the system processor; decompressing, by the system processor, the compressed packet according to a compression algorithm; and responding to the failure of the system processor in decompressing the compressed packet, sending out a compressed packet invalidity prompt, and canceling the firmware upgrading.
In some embodiments of the invention, further comprising: in response to the system processor successfully decompressing the compressed packet, resending the compressed packet to the expander; the compressed packets are received by the expander and decompressed and upgraded again.
