Use the Locate Disk Drive option to physically locate and identify one or more of the disk drives in a expansion drawer by activating disk drive LEDs.
To physically locate a disk drive or disk drives, in the Physical pane of the Logical/Physical tab, select the disk drives, and select Disk Drive >> Locate >> Disk Drive.
The LEDs on the selected disk drives blink.
When you have located the disk drives, click OK.
The LEDs stop blinking. If any other locate operations (Locate Array, Locate Storage Subsystem, Locate Disk Drive Channels,
or Locate Expansion Drawer) are currently being invoked from another , these LEDs also stop blinking.
In the rare case that the LEDs on the disk drives do not stop blinking, in the Subsystem Management Window, select Storage Subsystem >> Locate >> Stop All Indications.
If the LEDs successfully stop blinking, a confirmation message appears.
