Description Because of all the original, we may need to look at the Linux Server board model, CPU model, memory size, the number of memory lines. Because the server uses a RAID card, the usual view of the hard drive information can not be used, to be added back later!

In fact, it is through the dmidecode command output, and then through the sed,awk,cut command processing. 2, this footstep applies to the HP DL series of servers, the Dell PowerEdge series will have a little content different, so there will be a small tabloid error in the crawl process.3.

For the Dell PowerEdge series of servers I have a lot of contact, and encountered a lot of failures, then I have encountered and the solution: 1, for the server can not start, the Internet has a variety of solutions, but the most practical is the elimination of the law, to determine which parts of the fault. First determine if the power supply is normal, then replace the memory, CPU, motherboard. (I encountered a bad memory, the server can not get up
