Mirrored harddisks
-
Hello, I have a server with Win2000 Server, which has two RAID harddisks mirrored. I guess one of the harddisks crashed, because when it boots i get the blue screedn with the error "BOOT_DEVICE_INACCESSIBLE". I tried to boot only from one harddisk, but it doesn't work. Since it's mirrored, i should be able to boot from the other harddisk and so i don't loose any data. My question is how to do that? Should i reconfigure some RAID options?

The version of that Stop message that I get alot around here is "INACCESSIBLE_BOOT_DEVICE". It's surprising easy to fix here, I don't know if this will work for you though. Get out the Windows2000 Server Setup CD or the 4 Setup floppies. Boot the machine on that disk and continue until you get to Install or Repair an existing installation. Pick Repair, then pick Recovery Console. When it asks you to pick the installation you want to repair, just type 1 and hit [ENTER] to pick the only installed version. It'll ask you for the Administrator account password. You DO NOT have to enter it! Just hit [ENTER] 3 times and it'll tell you the login failed and the machine will restart. Great...just hit [ENTER] and pop the CD/Floppy out. Done! ... At least that's how it's fixed around here ... Dave Kreskowiak Microsoft MVP - Visual Basic

What this message means is that once it gets to stage 2 of the boot process, it can no longer see the disk it's trying to boot from. This normally means that you need a boot-time disk/disk controller driver. However, this is something that doesn't normally stop working so I'm a bit mystified as to why it has. It's possible that you have (or someone else has) deleted NTBOOTDD.SYS. To restore, work out what driver you're using and copy it back onto the disk. It may be easiest to do a repair as Dave has suggested - you'll need the floppy that came with your RAID controller for Setup to be able to see the hard disks. Another situation in which you might get this message is if you try to use a disk image built with different hardware to the one you're installing it on. In that case a repair is normally the only option if you want to continue with that image. Stability. What an interesting concept. -- Chris Maunder

When you mirror two disks you do not have both disks active. If the active disk of the mirrored pair fails, you need to make the disk active. Load a boot disk (CD or Floppy) with fdisk, follow the prompts to make the disk active. Reboot and it should find the disk and boot. Cheers

Hi dave, Thanks for your answer. Unfortunally, this way didn't work. Once i choose the Repair option, it can't find any installation of a Windows Server, so the only option i have is to cancel or to go back. That's why i can't get to the Recovery Console screen. Take care! Bogdan

Hey Mike, Thanks for your idea. I have q question though. I tried Dave's way, but it can't see the installation (see my reply to dave). I have a diks of the RAID controller, that has the driver. Is this the disk to use (and if yes, how? boot, or some other way?), or should it be another disk? Regards, Bogdan

Hey, Thank you for your help. What disk should i use) I tried win98 stratup disk, and then fdisk, but there is no option for active hdd. Should i use the option with active partition? Works that for disks as well? If not, then what disk should I use? The Installation CD, as far as I know, doesn't have such on option like fdisk. Thanks a lot! Bogdan

You have to load the drivers during the startup of Windows setup. Watch the bottom line of the screen carefully. You'll eventually see an option to hit , I think!, to load 3rd party disk drivers. Hit it, the follow the instructions for loading your RAID controller driver off that disk you have. Dave Kreskowiak Microsoft MVP - Visual Basic
