Replacing, moving, or adding hard drives 24 Effects of a hard drive failure When a hard drive fails, all logical drives that are in the same array are affected. Each logical drive in an array can use a different fault-tolerance method, so each logical drive can be affected differently. • RAID 0 configurations cannot tolerate drive failure. If any[...]

Replacing, moving, or adding hard drives 25 If you insert a hot-pluggable drive into a drive bay wh ile the system power is on, all disk activity in the array pauses for a second or two while the new driv e is spinning up. When the drive has achie ved its normal spin rate, data recovery to the replacemen t drive begins automatically (as indicated b[...]

Replacing, moving, or adding hard drives 26 Time required for a rebuild The time required for a rebuild varies co nsiderably, depending on several factors: • The priority that the rebuild is given over normal I/O operations (you can change the priority setting by using ACU) • The amount of I/O activity during the rebuild operation • The rotat[...]

Replacing, moving, or adding hard drives 27 2. Restore data from backup. Case 2: The replacement drive has failed. Verify that the replacement drive is of the correct ca pacity and is a supported model. If these factors are not the cause of the problem, use a different drive as t he replacement. Case 3: Another drive in the array has failed. A driv[...]

Replacing, moving, or adding hard drives 28 Mo v ing dr i v es and arr a y s You can move drives to other ID positions on the sa me array controller. You can also move a complete array from one controller to another, even if the contro llers are on different servers . Before you move drives, the followin g conditions must be met: • The server mus[...]
