The internal drives can be taken offline when there are problems on the drives by clicking
Take Offline in the Actions drop-down menu. A confirmation window opens (Figure 7-6).
The IBM Storwize V7000 storage system prevents the drive from being taken offline if

Chapter 7. Storage pools 229
The internal drives in the IBM Storwize V7000 storage system can be assigned to several
usage roles, which either can be unused, candidate, spare, or failed. The meanings of
these roles are:
– Unused: The drive is not member of an MDisk (array).
– Candidate: The drive is available for use in an array.
– Spare: The drive can be used as a hot spare if required.
– Failed: The drive was either intentionally taken offline or failed due to an error.
Click Mark as... in the Actions drop-down menu, and select the role you want the drive to
be assigned to (Figure 7-7).

redundancy is lost on the array, could lead to potential data loss.
