CentOS

hi i try installing centos 7.3 in ucs c22 m3 standalone. i try following the documentation but still don't work how to detect the raid. i try to install the driver like this. but i don't know it is successfully install or not. and still after this i can't detect the raid. I tried installing Windows Server 2012 R2. The installation can detect raid and is installed successfully. this is an old server. and I don't know what was done before with this server.

Do not use CentOS 7.3. It is over 3 years old and has 3 years of security vulnerabilities present. In addition, it's also missing all hardware support for anything that's been invented in the last 3 years.

The current and only supported version of CentOS 7 is 7.7. Use that.

Also, "ddf raid" in your screenshot almost certainly means it's FakeRAID not hardware RAID and the recommendation in such cases is to disable the RAID functionality in the "controller" BIOS and install using Linux software RAID.

i use centos 7.3 because this os is almost lastest supported in ucs support tool https://ucshcltool.cloudapps.cisco.com/public/.
i will try to disable the raid later.
i want to ask again when i try use centos 7.0 the raid/drive can detect but unknown and can't partition.

Only 7.7 is supported.

hi i try to disable fake raid and delete the raid. but still can't detect the drive. but if i enable this fake raid and not configure the raid i can detect the raid but i think i can't boot this os(process installing). i try to use centos 8 and 7.7 and still same.

successfully install. but when i try to reboot i can't boot to centos 7.7. and when i try to check the bios boot option. i don't have disk/raid option
