UCS: flashing cursor after installing Linux (RedHat, Suse), server would not boot

by on Jan.04, 2013, under Cisco, UCS

Here is an interesting thing that happens during Linux installation on Cisco UCS blade.
After installing Suse on Cisco UCS blade, the server would not boot and only flashing cursor is seen. Tried other version of Suse and even RHEL, still the same. This looked strange because I had installed Linux on UCS without any problems before.
There is a small thing that you need to be aware when doing installation. Make sure to add CD-rom in boot order in the the service profile and after you mount your ISO let the sever to pick it up itself. Do not press F6 and choose for it as this is where interesting thing happens.
When you let the server to pick the boot device it makes Linux installer to think that this server is running in UEFI mode.
When you press F6 and choose the boot device the installer thinks it is BIOS mode and when partitions are created, it messes things up there for after reboot you see flashing cursor.
