Re: booting from mirrored drive
GO TO STAERT AND CKICK ON IT ... WHERE IT SAYS "RUN" TYPE IN CHKDISK. ALSO CLICK "START" AND CLICK ON "SEARCH" SEL;ECT ALL FILES FOR SEARCH AND TYPE IN CHKDISK .... THIS MAY TAKE A WHILE. IT WILL SHOW EVERY LOCATION OF CHKDISK.
CLICK ON EACH ONE AND CLICK OPEN OR RUN.
ALSO CHECK ADMINISTRATOR/USER TO MAKE SURE YOU ONLY HAVE ONE. ITS LOCATED UNDER CONTROL PANEL.

This is because either the image on the hard drive is bad (corrupted, missing boot sector, etc) or because the hard drive itself has some issue like corruption etc. If this is a mirrored raid array (two drive mirroring each other) I would try to remove one of the drives and boot again. If that does not work reinsert and remove the other drive and try to boot.
If you know the two drive that are the OS mirrored drive, remove the failed drive and replace it with the good mirror drive and boot the system. If the drive and the OS is good the system will boot from that drive. You can now mirror this drive with a good disk.
This is a quite serious matter to be solved. The information you have provided is not enough at all.
What you have to include in here:
First, Be precise. Don't assume.
How did you recognized the failure. Which indicators or POST/BIOS/RAID BIOS reported you the errors? Was it from the OpenManageSA?
Please specify the Hardware Controller model and manufacturer with the version (RAID controller).
Which Operating System do you run (or ran)?
Are these disks Hot Swappable?
Have you used hardwareRAID controller or software RAID? Provided by OS.
Do you have Dell OpenManage Server Administrator?
How do you describe the RAID configuration? Are you sure that Disk 1 and 4 are mirrored to 2 and 3? You must be precise. Because raids can be used in many ways. You can combine any two disks and mirror them to any two disks. Even though it prevents hard drive failures, if your OS had an issue Mirrors may not be an option to recover it.
That message is a Warning Message. However Drive Roaming has completed. You don't need to worry about that.
If your BIOS has associated firmware controllers you could rebuild the array. But you may have to add new disks to replace others. You may need to update the firmware if necessary.
Then if you plan to use disk 2 and 3, you have to position them to 1 and 4. Then try to rebuild the array. But you may have to have Controller Drive installed on the disk. That varies from type to type. So I cannot say exactly. However if the mirroring of the OS is done to one disk, that disk would be enough. But you have to be certain. Reconfiguring should be done using both the disks replaced if you do not know anything about the configuration.
Check BOOT ORDER. Change it if necessary. If disks fail again check one by one and repair them using a separate machine.
Use Dell Software (OpenManage Server Administrator, if its the one available). Rebuild and or Resync the array.
If boot record errors occur, you have to boot from CD/DVD and repair the Boot Record and/or MBR.
If you need any other issue like BSOD, please write them down. Make sure the OS is not corrupted. If you backed up the System Status, restore it in such a case. Do an In-place Upgrade otherwise (will replace the OS files only, not data).
Use the manuals for Dell Server and RAID Controller if you do not know how to use properly.
If all the options are not working, you have to contact an engineer at Dell.
Feel free to contact again.

As RAID uses block for block copy, a re-sync when adding in a new mirror on RAID 1 will take some time, and system performance will be affected during that time period. There is no indication in windows if the rebuild is complete as this is being done on a hardware level by the controller. Both Raid 5 and RAID 10 have added benefits , but alos require more storage (a lot more in case of RAID 10 as you will have effectivly 3 spares for 1 data.) Raid 5 has the best space/protection pay off, but will be slightly slower than both RAID 1 and RAID 0 as parity has to be calculated for each write. As caffineshark states your best option is to use a combination of the methods we have described:
1) Use the two SATA disks as RAID 0 for performance and reliability. 2) Make backup images of the boot volume using Drive Image / Ghost and store on external USB IDE drive, and then offsite.
If you make an image in the USB drive, make sure you run a verfiy of the image after creation to make sure it's valid.
This should allow you to restore in a DR sutuation, but also give you some decent HDD crash protection.
Check the Boot Sequence again -- if there are any "SCSI" devices listed, enable them, and make your CD-ROM the "primary" boot-device (so that you can install Windows) and make this "SCSI" device the SECONDARY boot-device, and disable the internal hard-drive, so that it won't be used as a boot-device.
hi, you need not have to upgrade the BIOS,, set the SATA HD on the IDE channel in the BIOS, or what options r avilable for SATA controller, if it is set to RAID, you will need a raid utility to format the SATA, or it wont shoe in windows, let ,e know
