ONTAP 9.14.1 commands ( CA08871-226en )
storage disk set-led
Identify disks by turning on their LEDs
Availability: This command is available to cluster administrators at the admin privilege level.
Description
The storage disk set-led command controls the LED of a specified disk.
You can turn an LED on or off, cause it to blink or stop blinking, or test it.
This command is useful for locating a disk in its shelf.
Parameters
-action {on|off|blink|blinkoff|testall|resetall}- Action-
This parameter specifies the state to which the LED is to be set. Possible values include the following:
-
on - The LED is lit steadily
-
off - The LED is not lit
-
blink - The LED blinks
-
blinkoff - The LED stops blinking and is not lit
-
testall - This tests the operation of every disk enclosure’s hardware and drivers per node. Do not use this value in normal operation.
-
resetall - This resets the LED of every disk on the node and lights up the LED of disks with faults.
-
[-disk <disk path name>]- Disk Name-
This specifies the disk whose LED is to be set. Disk names take one of the following forms:
-
Disks are named in the form
<stack-id>.<shelf>.<bay> -
Disks on multi-disk carriers are named in the form
<stack-id>.<shelf>.<bay>.<lun> -
Virtual disks are named in the form <prefix>.<number>, where prefix is the storage array’s prefix and number is a unique ascending number.
-
Examples
The following example causes the LEDs on all disks whose names match the pattern 1.0.* to turn on for 5 minutes:
Cluster1::> storage disk set-led -disk 1.0.* -action on -duration 5
The following example causes the LEDs on disks 1.0.0 and 1.0.1 to turn on for 2 minutes:
Cluster1::> storage disk set-led -disk 1.0.0,1.0.1 -action on -duration 2
The following example causes the LEDs on all disks attached to adapter 0b on Node2 to turn on for 1 minute:
Cluster1::> storage disk set-led -node Node2 -adapter 0b -action on -duration 1
The following example resets the LEDs on all disks on the local node and causes the LEDs of disks with faults to turn on:
Cluster1::> storage disk set-led -action resetall
The following example tests the LEDs on all disks owned by the local node for 3 iterations:
Cluster1::> storage disk set-led -action testall -iteration 3
