Question about HP NetServer LH3

1 Answer

I have an HP Netserver LH3 with 2 processors, 512MB memory, and RAID 5 array. Someone took the drives out of the machine, and the sides off of the box, and tried to blow the dust out using canned air. Person claims they have done this before - every 6 months or so. The machine is in a textile mill office so there is a lot of dust in the air. Unfortunately this time when system was out back together, the system wouldn't boot : No operating system found. We tried swapping disk drives in the cage in case they went back in the wrong order. Still no operating system. We replaced on of the drives and 'rebuilt' it using express tools. Now system gives message OS Loader 4.0 - Windows NT missing 'something' never says what the problem is. I was able to find the HP NAvigator disk and create DiagTools diskettes. When run, everything comes up ok, but the PCI Bus Stress Test using - PCI Bus Master Cycles. Fails with error code:008A. Help! Does anyone know which board this is referencing and would this cause the system not to find Windows? Could this be a loose connection? Or are we up the rapids?

If you removed the drives in a RAID 5 array and did not get them reinstalled in the proper order and your OS was on your array .. your toast ... well leastwise a modest amount of testing will be required ... how many drives ?
if you have 3 .. there is 6 possible combinations; 4 - 15; 5 - 31 ..
If it were me and important data was on the system w/o a backup .. I'd go though the task of trying all possible combinations.
easyiest way .. put a masking tape tag on each drive each with a different number .. create a chart based on the number of drives .. like
3 - 2 - 1
3 - 1 - 2
1 - 2 - 3
2 - 1 - 3
1 - 3 - 2
2 - 3 - 1

go through all possible combinations and attempt to boot ..

if you have a backup and or the data is not important .. recreate the array and reinstall the OS ..

Install new OS


Use the HP Smartstart CD and configure the with array with 2 arrays and 2 logical drives. The first with OS array on RAID 1 (2 drives mirrored). The second array on RAID 5 (3 drives minimum).

I have a server with a Serveraid 4H controller card, set up with two Arrays. Array B has 3 72GB drives set up as RAID 5. I would like to add 2 more drives to this array. Is this possible or do I have to...


I am not familiar with your RAID controller card but as long as the controller can see two additional drives, it shouldn't be difficult to add two new drives to your exisiting RAID 5 configuration.

You will probably need to reinitialize the RAID configuration for discs to copy all the parity information so you should refer to the documentation on re-initializing the RAID.

I have got a 3 disk raid5 IBM xseries Server which does not boot. How can I resque data from these disks?


I'm going to go out on a limb and assume that you don't have a good backup of the data on your RAID array. So, generally speaking, the operating system is probably installed on a separate disk from your raid array (not a guarantee). But if this is so then you should be able to reinstall your operating system and drivers (esp RAID controller) to that (separate) disk and you're off to the races (replace this system disk if necessary). -OR- Depending on the make of your RAID controller you may be able to transplant your RAID controller into another machine and all the original drives along with it, so long as it has a battery backup and you place all the drives in their original order. If there is no battery backup on your RAID controller then DON'T PULL THE PLUG ON THE ORIGINAL MACHINE AND DON'T EVEN CONSIDER removing the RAID controller in any way. If you have any doubts, whatsoever, have someone with experience in RAID arrays do the work for you. It will be well worth it! (RAID arrays aren't for the faint of heart)...

The system is setup using the RAID 5 config, now out of 5 drives it says 'OK' for 3 drives on 0, 1 & 2 and for 3 & 4 it says 'Replacement'. Is there any way of finding the correct Logical sequence...


Dont you have any levelling inside the machine? Go open and check.

When you have replaced the 2 defective drives with a new one, restart the computer and Raid 5 will automatically rebuild.

Harddrive array sequence causing system in booting


If the only drive you changed was the drive that failed and all the others are in the correct sequence, then that's a good thing.

The next question is, did you have this system setup in a RAID Array and if so, what RAID configuration were you using (RAID 0,1,5, etc.)? Some RAID configurations allow you to replace a failed drive and not lose data, but I will need to know more about how you set the system up in order to help you more.

Drive array problem


Hi Nick ,

As of now you can Select "F2" to accept data loss and re-enable logical drive. This Load OS Normally .
It seems that one of the HDD in the RAID 5 has failed , Did you notice any LED indications like red or amber on the HDDs ?? if so get that hdd replaced . Make sure the Failed HDD is replaced .
You can run the Array Diagnostic Utility from HP System tools to check the Failed Drives and also frimware version of the controller . If the frimware is not latest Update it from HP website. DL380 G4 should have Smart Array 6i controller .

Hope This was Helpful
cheers :)

Raid w/ hard drive defunct


Well lets make some assumptions
1. You have a Raid 5 System
2. You only have 3 drives in the Raid ARRAY
3. Only 1 drive has failed

To fix the problem you should only need to Replace the Failed Drive
Then start the raid management software or bios
Rebuild the array

If you have more than 1 drive failed in a RAID 5, and still must recover the data it is possible. But very expensive. Still fixable however.
