In a similar way as was described a few pages before with the RAID 1 Array Drives, this func-

tion is designed to replace a defective drive of a RAID 4 or RAID 5 Array Drive, while the sys-

tem continues to be fully operational.

There are typically two different applications where a Hot Plug is necessary.

Application 1.

The RAID 4/5 Array Drive is in the ready state.

It is likely that a drive will soon fail (for example when there is a loud operating noise). As a

preventative measure, this drive ought to be exchanged now, that is, in a moment when the

Array Drive is still in a ready state and still has redundancy.

Application 2.

The RAID 4/5 Array Drive is no longer fault tolerant (fail state), because a

drive of the Array Drive has actually failed. The Array Drive is still fully operational, but it

does not have redundancy any more. If another drive should also fail, the Array Drive's

functionality is impaired.

We assume that there is a RAID 5 Array Drive which is fault tolerant. Its state is ready, all

drives are valid. After selecting the Array Drive, we choose the Replace Drive option.
