Emergency Server 2k down blue screen

By mmbc_voltron ·
This weekend I came in and my server had a blue screen non_accesible_boot_device. I rebooted and tried to boot last known good config. Nothing. I Started the setup from the CD and had to specify the drivers for my Scsi card. I tried recovery console but said no vaild partions avalible. Then I tried the normal setup but the repair options was not there.
It wanted to install a fresh copy and my partition was blank. I had a C and D.
now it is just one big un-partitioned drive. how can I recreate the MBR or boot file. I don't want to have to reload but I guess that is what I am going to do.

Before you go too far, check the SCSI setting to see if there is a failed drive. It may be that the controller just doesn't see the drives correctly or there is a failed drive in the array. If, however, you have already started to load the OS again it may be too late.

From the BIOS go into the SCSI setup and verify that the card sees all of the drives. If it see all of the drives but not the correct array configuration, power the machine down, open the case and reset the SCSI controller BIOS. Depending on the card you may be able to simply pull the battery off and reseat it much like you do on the motherboard. If the card has no battery try pulling the card out and reseating it. Then power the box back up and again check the BIOS to see if the array is now visible correctly.

If you still cannot see the array correctly but can see all of the drives you are going to have to rebuild the server. I hope you have a valid backup of the server?

Good Luck. Let me know how it turns out.

the exact numerical error might help
so the drive being detected by the scsi controller at boot? (watch the black screen)
if yes, maybe you booted with infected floppy?
you can try fixmbr from the Recovery Console
wonder if spinrite or maybe PartitionMagic could help.

From your description it sounds like the system is not seeing your hard drive. On bootup, does the scsi controller see your hard drive(s)? If not, either your system HD went south, or there could be a bad connection, either to the drive or the scsi card. Try removing and reseating all scsi ribbon connectors before taking more drastic actions. Verify on bootup that the drive(s) are listed correctly in the scsi inventory.
