The invention discloses a device for detecting 80C31 single event effect. A power module supplies power for a main detecting CPU and a detected 80C31; a current acquisition card acquires the current supplied for the detected 80C31 and sends the acquired current value to a host computer; when the current value exceeds the preset threshold value, latch happens; the host computer sends command to the power module and a power module 0 disconnects power of the detected 80C31; the main detecting CPU receives codes of test program from the host computer through a serial port and writes the received codes in SRAM; the detected 80C31 reads the codes from SRAM and operates the test program according to the read codes as well as stores the program operation results in a double-port RAM temporarily; the main detecting CPU extracts the operation results from the double-port RAM and sends the results of occurrence of single event upset to the host computer. The invention realizes the online downloading and revision of the test program with complete test contents and high device reliability.

The present application discloses an access control method, device, device, and medium. The method includes: using a preset iSCSI protocol capacity query algorithm to query the target information of the volume under the storage device connected to the iSCSI client; The target information judges whether there is an unauthorized access volume that the iSCSI client has no right to access in the volume under the storage device connected by the iSCSI client; if yes, then an error message is sent to the local kernel, so that the iSCSI client The volume without access is not accessed. In this way, the access control of volumes on the storage device side can be performed without affecting normal business operations, avoiding data loss and other problems, and realizing online modification of the access rights of different volumes on the same storage device side.
