Using shell scripts to check server hardware information

1, in order to facilitate the query server hardware information, will need to query the content into the shell footsteps, output their desired format. 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. The steps are as follows:

4, here only for server manufacturers, memory, CPU configuration and network card information, for hard disk information can be based on different manufacturers of management tools to obtain. HP uses the HP-HEALTH-*RPM,G9 version above using hpssacli-*.rpm, which is used after installation: Hpacucli Ctrl all show config to view raid information. Dell installs the Dell OpenManage Server Administrator Tool view, which is viewed by command: Omreport storage Pdisk controller=0.

5. Viewing RAID information can also be viewed using the MEGACLI Open Source Tool, which is not described here.
