The Blink task allows you to find a device within a system by blinking the status LED on the device. If you
need to cancel the Blink task or if the physical device continues to blink indefinitely, use the Unblink task.
Preparing To Remove An NVMe PCIe SSD
WARNING: Both the Identify device and Prepare for removal LED patterns consist of a quick
on/off blink of the green LED. When you initiate a prepare to remove operation, ensure that your
NVMe PCIe SSD is no longer accessible by the system before you physically remove the NVMe
PCIe SSD.
CAUTION: To prevent data loss, it is mandatory that you use the Prepare to Remove task before
physically removing a device.
Use the Prepare to Remove task to safely remove an NVMe PCIe SSD from the system. This task causes
the status LEDs on the device to blink. You can safely remove the device from the system under the
following conditions after you use the Prepare to Remove task:
• The NVMe PCIe SSD LED blinks in a pattern that indicates that the device is preparing for removal. See
table NVMe PCIe SSD States and LED Indicator Codes.
• The NVMe PCIe SSD is no longer accessible by the system.
To perform the Prepare to Remove task:
1. Ensure that there is no I/O traffic running on the PCIe SSD.
