Steps to solve the issue:
- With help of ipmiview, plug in the ssb installer .iso file into a virtual CDRom, then boot the system from that virtual cdrom.
- When the cdrom has booted the installer, DO NOT answer yes! Switch to the second console with either alt-f2 or alt-right. This step might need using keyborad macros on ipmitool.
- On the second console please log in as root. The password is: default
- assemble the md device and mount the filesystem from it:
mdadm -A /dev/md0 /dev/sdb2 /dev/sda2 && mount -t ext4 /dev/md0 /mnt/boot
- Now you can see the relevant files under /mnt/boot. Inside that you should found grub directory, and grub.cfg
If you edit grub.cfg with vi, you have to delete this two lines:
password_pbkdf2 root grub.pbdkf2.sha512.[password_hash_here]
If you deleted this two line, just save grub.cfg
- You can also check if the kernel and initrd files are there. They should, but if not, that could explain why grub was unable to start the system.
- After you've investigated the situation, and fixed grub.cfg, you should umount /mnt/boot
Then mdadm --stop /dev/md0
Then you can reboot. This time you can unplug the installer cdrom, and let the system's boot procedure continue.
