Background: there is a dell R720 server in the computer room that does raid5 and raid5 is relatively safe. But this time the server flashed two yellow lights, and the system couldn't get in. Of course, the applications in the system can't be used.

Okay. Then restart and enter the LC. Dell server comes with a Lifrcycle Controller (server life cycle controller), boot F10, restart several times is also unable to get in. Looks like LC may not be faking it. Then ctrl+r directly into raid and see that there are two hard drives displaying error. One piece displays the no error. It means the hard drive is broken. It has nothing to do with the array card. Okay. Recognize bad luck and change the hard disk installation system. I bought three hard drives directly.

First, create a raid

(due to unable to enter LC. Raid5 can only be added to the array card.)

1. Start the server and press ctrl+r when RAID Controller BOIS appears. Press ctrl+r to enter the BOIS of the whole card. If you do not enter, click a few more times.

2. Select the raid card and press F2 to select Clear Config to clear the entire line of card configuration.

3. Select the raid card, press F2 to select Create NewVD to create a new virtual disk, then select raid5, and select three physical hard disks in use. Press ok. I use 3 300g disks here to do raid5, if there are more disks, you can also do hot spare.

4. Select the newly created virtual disk and press F2, and then select Start Init in Initialzation to initialize. (you can also choose fast init)

After initialization, press Esc to exit and restart Ctrl+Alt+Delete.

II. Installation system

Insert the CD, boot and jump directly into the CD installation. When selecting the hard drive. The hard drive won't be found. Download address: http://pan.baidu.com/s/1c294hu4 and choose to browse this driver. You can see the hard drive after installation. Then install the system on c disk.

Description: if there is a LC. Installation will be more convenient and faster. LC can do raid, can install the system.

III. Dell iDRAC configuration remote access management

IDRAC, also known as Integrated Dell Remote Access Controller, is an integrated Dell remote control card, which is a unique function of Dell server. IDrac card is equivalent to a computer attached to the server, which can realize one-to-one server remote management and monitoring. It communicates with the management chip BMC on the server motherboard to monitor and manage the hardware status information of the server. It has its own system and IP address, regardless of the OS on the server. It is a sharp weapon for administrators to access and manage remotely. Dell servers integrate iDRAC control cards, so we can throw away expensive KVM devices. In Dell's 12th generation servers, the version of iDRAC has been upgraded to iDRAC 7

First, we need to enable the iDRAC function in BIOS, start the Dell server, press F2 System Setup, open the BIOS interface, and select iDRAC Settings

2. Select Network in the IDRAC Settings interface

3. Enable NIC in the Network interface, and select the NIC interface. My side is LOM1.

4. Set the iDRAC IPV4 address

You can also set it through the server display window (briefly)

5. After the configuration is completed, you can manage it through the web page.

After opening this page, you need to change the default password.
