Internal drives: Choosing the option to take internal drives offline could lead to
potential data loss.
The internal drives in IBM Flex System V7000 Storage Node can be assigned to several
usage roles, which either can be unused, candidate, spare, or failed:
– 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 8-7).
