HP NetServer LH 3r Error Messages

[chico williams]

I'm using RAID 5 with 3 hard drives and all 3 have green lights but the server will not boot. There are several error messages:
1. Symbios In. PCI boot rom, no supported devices found.
2. DRam = 16 mb cluster= not supported, 120 = enabled
1 logical drive(s) found
1 logical drive(s) failed

3. Unresolved config mismatch between disk(s) and NVRam.

4. PXE-E53: No boot filename recieved
operating system not found.

Thanks, any help will be greatly appreciated.

Well the message of 1 logical drive found is from the Array controller and there must have been a message not listed here from the Array controller when the BIOS loaded, scanned for devices, and presented the option of pressing to enter the BIOS, yes? Do so to see the configuration.
It is reporting that the logical drive has failed for some reason, so either the controller has lost its configuration data (which seems logical with the mismatch error meaning what was stored on the drive does not equal what is in the controller).
Get into the BIOS and let it try and resolve things for you and save it. see if it comes back. DO NOT INITIALIZE if asked, this is a format of the logical which you do not want.

There are several options: Configure, Initialize, objects, format, rebuild, check consistency, disable bios and Alarm control. Which do I chose? There's only 1 drive online, ID 3 A0-0. The other 2 ID 8 and 9 (A0-1 & A0-2)are red.

Well that explains it, 2 drives have failed and the Lgoical drive is lost.
Try removing the drives, one at a time, and reinserting them into the same slot. then look again. See if they are still showing failed. If you can not restore at least one of the drives, the logical drive is gone forever. If you can get at least one going, BACKUP quickly

[chico williams]

After further testing I've discovered the following:
1. ID3 A0-0 is the only slot functioning online status.

2. ID8 & ID9 does detect the drives in their slots. If you remove the drives there's a "not responding" message. When in the slot it displays the drive ID and size, but remains as "failed" red.

3. If you place either ID8 or ID9 in the slot of ID3 they both read "green" and on line.

4. If you place ID03 in slot of ID8 or ID9 it still displays as "Failed" and red.

What does this mean? I do have a backup tape of this server from last week.

Well could be the backplane itself.
You you want you could try and restore the array from different slots.
put the drives back where they started.
enter the BIOS and record how they were selected A0-0, A0-1 and A0-2 and label them as such by which light blinks when you highlight each drive. Now you can move the drives to different slots, delete the existing array and reselect the drive in the same order they were before, creating a new array. Save the info, but when it asks you or warns you that the Initialize the new array (that would format it and it is already formatted), just hit and exit the BIOS, restart the server.

Hi chico,

you may be able to force the disks back online. If it works and it keeps happening it could be a failing disk

Why do you guys keep calling me Craig? My name is Sean. Or Mr. Craig if you prefer.

Chico,

The unresolved config mismatch is the issue you need to start with. The first thing you should do is record your physical and logical drive configuration. From M, go into Objects-->Physical Drive and Objects-->Logical Drive and write it all down. If all the disks are good, you can even clear the config and recreate it without partitioning it but you run the risk of corrupting your stripe set if the array was running in a degraded state for any length of time.

The safest thing to do is force one drive online and see if it boots. If Windows attempts a scandisk, don't let it. Reboot and fail that drive and force the other one online and try again.

Once you get to the O/S, then you can rebuild the remaining failed drive.

The reason ID's 8 and 9 still say failed is because you cannot rebuild from an offline state; only a degraded state and reseating the drives won't change that. Don't move the drives, just keep them in their original positions. If all 3 id's show the drive size, you're okay.

Hope this helps,
