No, I'm not. But I cannot access /dev/sda. |
7 |
From a terminal (LiveCD booted): |
8 |
# fdisk /dev/sda |
9 |
Unable to open /dev/sda |

|
11 |
I may access /dev/sdb though (that's why the I installed Gentoo on sdb). |

I'm not sure how to do that. I'm not even sure if /dev/sdb is the actual |
19 |
RAID or just one of the drives? But when I come to think about it... |
20 |
when I try to boot the system, the Dell server actually boots from the |
21 |
logical drive and it do find the kernel, hence /dev/sdb is infact the |
22 |
RAID, right? |
23 |
I also removed one of the drives, tried to boot (it finds the kernel), |
24 |
then I removed the other drive and rebooted and it still finds the kernel). |

lsmod gives one interesting module: megaraid_sas (if I recall |
31 |
correctly). And I guess this is one of the many LSI entries in kernel |
32 |
configuration, and I have tried enabling them all. |

I agree, something is wrong indeed! |

Not at all and I don't know how to figure that out either. I was told to |
42 |
check /sys/ from the LiveCD and check which module was used for /dev/sdb |
43 |
but I couldn't find anything (that I found) interesting. |

I have tried that too! I have also tried genkernel and modified it to |
50 |
build support for LSI drivers. |

I can't see how this could make any difference when I can't even mount |
57 |
the root device? Anyway, I'm desperate and will try this as soon as I can. |

Thanks for your help, |
