Locating an expansion enclosure

You can use the Blink option to physically locate and identify an expansion enclosure in the storage array.

The LED activation varies according to the type of expansion enclosure that you have.

If you have an expansion enclosure with a white LED, the Blink Expansion Enclosure operation causes the white LED on the expansion enclosure to come on. The LED does not blink.
If you have any other types of expansion enclosures, this operation causes the appropriate LED on all of the physical disks in the expansion enclosure to blink.

To locate the expansion enclosure:

Select the Hardware tab.
Select a physical disk in the expansion enclosure that you want to locate.
Select Hardware > Blink > Expansion Enclosure.
The LED or LEDs on the expansion enclosure or physical disks come on.
When you have located the expansion enclosure, click OK.
The LEDs stop blinking. (If you have an expansion enclosure with a blue LED, the LED goes off). If any other blink operations (Blink Storage Array, Blink Disk Group, Blink Physical Disk Ports, Blink Expansion Enclosure, or Blink Physical Disk) are currently being invoked from another storage management station, these LEDs also stop blinking.
If the LEDs on the expansion enclosure do not stop blinking, from the AMW, select Hardware > Blink > Stop All Indications.
If the LEDs successfully stop blinking, a confirmation message is displayed.
Click OK.
