7.1.1 Actions on internal drives

There are a few actions can be taken on internal drives when you select the drive and

right-click it, or click the Actions drop-down menu (Figure 7-5).

Figure 7-5 Take actions on internal drives

򐂰 The Fix Error action starts the Directed Maintenance Procedure (DMP) for a defective

drive. For more information about this topic, see Chapter 13, “RAS, monitoring, and

troubleshooting for an IBM Storwize V7000 system” on page 521.

򐂰 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

there might be data loss as a result. A drive should be taken offline only if a spare drive

is available.

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).

򐂰 Use the Identify action to turn on the LED light so you can easily identify a drive that

needs to be replaced, or that you want to troubleshoot.

Internal drives: Choosing the option to take internal drives offline, even though

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

provides more information about the drives (Figure 7-9).
