RHEL6.7 grub won't boot up after install on Dell R730XD

Latest response

Brand new install of RHEL6.7 on Dell R730XD w/ PERC H730P raid1 disk using BIOS mode. Installation using kickstart thru PXE boot worked fine, but after the install, the system will not boot up. Always hang before grub even kicked in. Last message was "Booting from Hard drive C:" and it stopped and hang.

Tried to install RHEL7.1 the same way, and everything works and the system boot up fine after install. Same BIOS setup on both. Without changing any BIOS setup, I tried it again w/ rhel6.7, same problem. After the installation is done, system will not boot.

Tried to do boot up in rescue mode using kickstart, then reinstall grub, reboot. same problem.

Anyone has seen this issue?

This thread looks relevant to the issue you are seeing. Or you could post your own in that Dell mailing list.

Thanks for the note. Yes I saw that thread as well, except that there was no real solution in there, I verified that grub was installed, then after that I reinstalled it , and still can't get it to boot. I am now trying to update the BIOS to the latest version. It still puzzled me that rhel7.1 works fine on it.

Ok, I think we figured it out.

By default, the serial communication in the BIOS is set as

Serial Port Address - Serial Device1=COM2,Serial Device2=COM1

and we had to set console=ttyS1,115200 in the kickstart append line. This allows us to install rhel 6.7, but after install it wouldn't boot, although the grub.conf is also set to use ttyS1

We swapped the COM assignment in the BIOS and now using console=ttyS0 in the append line and everything works as expected.

What puzzled me earlier was the fact that RHEL 7 worked fine w/ the default serial COM setting using ttyS1. I guess rhel7 made some improvement that allows it, or there might be some bug in rhel6.7 for using ttyS1

I just experienced the same problem with RHEL 6.5 on the Dell C6320 with console redirection over COM2 (ttyS1). After changing console redirection to COM1 and changing the bootloader to ttyS0 the system booted fine. BIOS version was 1.0.3, tried updating to 1.1.4 but made no difference.

I've had the same issues, but was able to fix the bug by: Reset Bios to Default twice Reset RAID Controller cfg to Default twice Reset RAID controller advanced settings to Default twice <-fixer Recreated the RAID's selecting disk type as BOTH not ssd or hdd but both Also have "part biosboot --fstype=biosboot --size=1 --ondisk=sda" from an earlier issue with builds on SSD *RHEL 7.2.1511 on PowerEdge R630 - Multiple servers - foreman-puppet automated builds.

part biosboot --fstype=biosboot --size=1 --ondisk=sda

Did this help? Running into same problem on SSD drives with an INTEL RST pseudo-raid
