hard drive - Dell Server HDD failing

I have a Dell PowerEdge 2950 which has 3 drives configured as a RAID 5 array. One of the disks is in a failing state. My question is: if I have a similar drive can I simply pull out the failing drive and insert the new one?

Answer

The right sequence is:

1. Prepare the disk to removal (from Dell OpenManage or other software that manage your raid controller).




2. Remove the fault disk.




3. Insert new disk.




4. Rebuild the virutal disk (from Dell OpenManage).
