Blinking or unblinking component LEDs
You can locate a physical disk, virtual disk drive and PCIe SSDs within an enclosure by blinking one of the Light Emitting Diodes
(LEDs) on the disk.
You must have Login privilege to blink or unblink an LED.
The controller must be real-time configuration capable. The real-time support of this feature is available only in PERC 9.1
firmware and later.
NOTE: Blink or unblink is not supported for servers without backplane.
Blinking or unblinking component LEDs using web interface
To blink or unblink a component LED:
1. In the iDRAC Web interface, go to any of the following pages as per your requirement:
● Storage > Overview > Physical Disks > Status– Displays the identified Physical Disks page where you can blink or
unblink the physical disks and PCIe SSDs.
● Storage > Overview > Virtual Disks > Status- Displays the identified Virtual Disks page where you can blink or unblink
the virtual disks.
2. If you select the physical disk:
● Select or deselect all component LEDs — Select the Select/Deselect All option and click Blink to start blinking the
component LEDs. Similarly, click Unblink to stop blinking the component LEDs.
● Select or deselect individual component LEDs — Select one or more component(s) and click Blink to start blinking the

3. If you select the virtual disk:
● Select or deselect all physical disk drives or PCIe SSDs — Select the Select/Deselect All option and click Blink to start
blinking all the physical disk drives and the PCIe SSDs. Similarly, click Unblink to stop blinking the LEDs.
● Select or deselect individual physical disk drives or PCIe SSDs — Select one or more physical disk drives and click Blink
to start blinking the LEDs for the physical disk drives or the PCIe SSDs. Similarly, click Unblink to stop blinking the LEDs.
4. If you are on the Identify Virtual Disk page:
● Select or deselect all virtual disks — Select the Select/Deselect All option and click Blink to start blinking the LEDs for
all the virtual disks. Similarly, click Unblink to stop blinking the LEDs.
● Select or deselect individual virtual disks — Select one or more virtual disks and click Blink to start blinking the LEDs for
the virtual disks. Similarly, click Unblink to stop blinking the LEDs.
If the blink or unblink operation is not successful, error messages are displayed.
