Your server has a RAID 1 array that gives a drive error when booting. Which of these would be the best next step?
A) Replace the bad drive
B) Replace all drives in the array
C) Reseat the drive controller adapter card
D) Replace the cables used by the faulty drive
E) I’ve found that shaking the computer doesn’t actually fix anything
The answer: A) Replace the bad drive
A RAID 1 is mirrored, so even if you lose one drive your system can still run and you’ll still have access to your data. Of course, you’ll want to replace the bad drive as soon as possible. When the drive is replaced in the array, the RAID controller will rebuild the new drive to properly mirror the existing data.
