Firstly, it is necessary to explanation, since storage-type server needs a fairly large number of hard disk, and hard disk needs are loaded in
On hardboard backboard, the limitation based on casing structure, usual one piece of hard disk backboard can not load all required hard disks, therefore, storage
Type server is necessarily required to muti-piece hard disk backboard and goes to accommodate all required hard disks.Exactly because the operation of storage-type server is using more
Block hard disk backboard then needs to be monitored using the muti-piece hard disk of BMC to muti-piece hard disk backboard and thereon, when hard disk backboard or
When hard disk breaks down, accurately determine that there are the hard disk of failure back in muti-piece hard disk backboard using the method in following embodiments

Default serial number 0 and 1；There are the hardboard backboards of 5 preamble bits, that is, the hardboard backboard sum of preamble bit is 5, then before this 5
The default serial number 0,1,2,3 and 4 of the hardboard backboard of set.
Step 202: according to default display information-hard disk backboard of default the display information and each I2C interface of mainboard
Corresponding table determines the target hard disk backboard of the corresponding default display information.
It is understood that due to I2C interface with hard disk backboard is practical connect after, based on the front/rear of hard disk backboard
The preparatory display information of data and default serial number composition I2C interface is set, then pair of the preparatory display information of each I2C interface of mainboard
Answer a hard disk backboard, that is, default display information-hard disk backboard of each I2C interface of mainboard is generated based on above-mentioned corresponding relationship
Corresponding table is simultaneously stored in advance, to search above-mentioned corresponding table after the default display information that step 201 obtains target I2C interface
