# Using Identify to work with your systems

When you click Identify for a tree object, the ServeRAID Manager makes the hardware light associated with the selected tree object blink.

Depending on what you clicked in the tree, you can identify the following:

- A drive
- All drives
- A channel of drives
- A logical drive
- All logical drives
- An array
- A spanned array
- All arrays

You can make only one selection at a time. The hardware will continue blinking until you click OK in the message window.

Identify works only on controllers with a SAF-TE processor and the appropriate firmware. The processor uses a SCSI ID; therefore, it is displayed in the tree as the following:

Enclosure

If a drive light or a series of drive lights do not blink, it is because all or part of the subsystem is not controlled by a SAF-TE processor.

For example, if SCSI channel 1 has a SAF-TE processor, but SCSI channel 3 does not, and you select to identify all physical drives, only SCSI channel 1 will blink.

Identify is particularly useful for enclosures, such as the Netfinity® EXP15. You can use Identify to clarify which drives in the enclosure you need to work with, before you pull them out of the enclosure.

If a SAF-TE processor is present and the controller supports drive identification, you can identify the components by doing the following:

Right-click: | To identify...
Controller | All physical drives on the controller
Arrays | All physical drives in all arrays
Logical drives | All physical drives in all logical drives
Physical drives | All physical drives
Hot-spare drives | All hot-spare drives
Array [number] | All physical drives in the selected array
Spanned array [number] | All physical drives in the selected spanned array
Logical drive [number] | All physical drives in the selected logical drive
Logical drives in array [number] | All physical drives in the selected logical drives
Logical drives in spanned array [number] | All physical drives in the selected logical drives
Physical drive [number] | The selected physical drive.
Physical drives in array [number] | All physical drives in the selected array
Physical drives in spanned array [number] | All physical drives in the selected array
Channel [number] | All physical drives on the selected channel
