Re: if anyone is still on the board...



Jessica,

I think you should probably fix the hardware before you try anything else
with the OS.
(you are clear that the OS 'does not know' that it is running on a hardware
raid, right? The server tells the OS that there is only one drive.
With software raid, like if you make a raid using Windows Disk Managenent;
the OS 'does know' that there is more than one drive.. this is a whole
differnt story!)

You said you had access to HP support? Did they have you run any diags on
the mainboard / raid?

Does this system have redundant power supplies? I have had 3 older systems
with similar problems.. power supplies tend to degrade over time.. You may
want to replace the power supply (especially if it is older and or there is
only one).. it may not be providing enough power to run all the drives,
fans, memory, and big processors typically in a server box.

Power requirements:
Component Requirement
AGP Video Card 30W - 50W
PCI Express Video 100W - 225W
Average PCI Card 5W - 10W
DVD/CD 20W - 30W
Hard Drive 15W - 30W
Case/CPU Fans 3W (ea.)
Motherboard (w/o CPU or RAM) 50W - 100W
RAM 20W per 1GB
Pentium III Processor 40W
Pentium 4 Processor 80W - 125W
AMD Athlon Processor 80W - 125W

For overall power supply wattage, add the requirement for each device in
your system, then multiply by 1.5. (The multiplier takes into account that
today's systems draw disproportionally on the +12V output. Furthermore, power
supplies are more efficient and reliable when loaded to 30% - 70% of maximum
capacity.)

I have had good results with “PC Power & Cooling” you can google them and
their phone support is great.

If HP has not had you run diagnostics on the Drives I suggest you move them
(one by one) to another machine and run IBM’s (Now Hitachi) drive fitness
test on them. You can get it here:
http://www.hitachigst.com/hdd/technolo/dft/dft.htm
If they pass run the tests using the server box.. this will help identify if
the drive, cable, or controllers are problems.

Good Luck… And at least you know you have a good backup to restore once you
know you have good hardware to put it on!

After restore which was successful, the raid failed again.

Can anyone advise how to get into active directory restore mode?
pressing F8 didn't work, that brought me into raid controller menu.

Thanks,
Jessica
