I have recently gotten a used R710 Server to use as a storage appliance.
I do however face some issues with it. Intially I installed WIndows 10 in order to get iDRAC and USC to the latest version in order to update the other components of the system.
After updating the firmware of all components through the USC Platform Update, I wanted to install CentOS 7 on the server.
First I tried using and SD Card in the SD Card slot of the server. The system boots fine on the CentOS 7.3 LiveGNOME Boot USB and also installs fine, but when it has to boot from the SD Card I get a lot of dracut initqueue timeout errors and then it says that a start job is running for dev/sdb3.device and this keeps running and never reaches the OS.
I retried with a normal SATA HDD connected through the hot-swap bays in the front, but I get the same result.
How can I get this to work with an R710? Any special procedure or drivers I need to install?
EDIT: It seems that it works both on HDD and SD Card if I burn a CD and install using the DVD-ROM drive of the server, but it should be possible to do with a USB-stick.
I have a similar problem with a R730 server. I can't even boot the live version. It simply hangs as soon as I select the option in the Menu. The same goes for the installation.
I have replaced the media and even installed another server with it. Worked like a charm, but not in this server. Ubuntu on the other hand could be installed.
Please check which drive CentOS is installing and did you select overwrite all partition ?.
did you installing BIOS or UEFI mode and what kind of hard disk in use like NVMe/SSD/SAS/SATA because you cant boot NVMe disk in BIOS mode.
I have an R710 also, and had CentOS 7 installed on it previously, though I'm not sure on the specific minor revision I had. The server worked without issue and I was using it as a home media and game server. What specific errors are you seeing? The community will be better able to assist if you can share the specific errors.
