So at what point do you shoot it to put it out of it's misery?
So I have a circa 2000 Adaptec RAID in an old server that used to be my SBS 2000 server and I needed to change out the drive in the raid and then I was forgetting how to get the raid back. Knowing that the raid unit is now considered 'out of support' and thus I'm left to google and the vendors support portal, I started to look at that box and wonder why I was trying to fix it back up. It takes electricity. It's an older box taking resources. It's to the point that I can't get support for it, so why not just move the info that's on it to my second Win2k8 box?
I remembered the last time I dropped a drive I had to do this 'zap' command, but there comes a point in time that you have to say "old hardware is putting my firm at risk" and plan accordingly.
And the plan is to move off this server.
It's back up and running now, but I'll be moving off of it and retiring the box.
It may be possible to retrieve the data assuming at least one of the drives is physically functional and the data on that drive is in tact.
If the drives are failed or dead, simply removing the RAID table information may allow access to the data. If a drive is marked as missing, that indicates the drive is not recognized on the bus. This may be caused by a faulty data and/or power cable or a faulty device. If possible, correct the hardware malfunction to get the drive(s) to a failed state.
Note: This procedure only applies to a RAID 1 array and is not guaranteed to provide access to the data.
To remove the RAID table information:
With the RAID drives attached to the controller, power on the system and press "CTRL-A" when prompted by the Adaptec BIOS message to access the SMOR (Storage Manager on Rom) utility.
Highlight the failed or dead "RAID-1" array.
Press "ALT-F10". You will not see any changes on the screen.
Press "ALT-Z". Again, you will not see any changes on the screen.
Press "ALT-A" to access the Action Menu.
You will now have an option to "zap" the RAID array. Zapping the array will delete the RAID table and allow you to maintain the partition table.
Select zap array. When the utility asks if you really want to remove the RAID table, answer Yes. You will then be asked if you would also like to delete the partition table on the drive(s), answer No. You will be prompted to reboot for the changes to take effect. On reboot, the adapter should report two individual devices during the post process in place of the RAID array. At this point, either of the two hard disks can be examined individually for data access. If you were booting from the RAID 1 array, one of the individual drives may still allow you to boot the operating system providing the data has not been damaged.
Before you return the system to production, it is recommended you attempt to determine and correct the cause of the failure
If you wish to return your system to a RAID 1 configuration, please for more information.
