Ungraceful System Shutdown Or Power Loss
If the host system experiences a power loss, the PCIe SSD may not have time to perform its internal shut down
procedure. In such an event, the device may enter a recovery mode which is indicated by the steady blinking of the
activity LED (On for 200 msec, Off for 200 msec). See figure PCIe SSD Carrier LED Indicators.
This recovery process is also known as rebuilding. During rebuilding, there is very limited access from the host
operating system. After the recovery procedure is complete, the steady blinking stops and the device is fully accessible.
CAUTION: Removing a PCIe SSD from the system without preparing the device for removal first, causes the PCIe
SSD to enter recovery mode the next time it is inserted in the system.
NOTE: The operating system event log displays events during the time period the PCIe SSD is in recovery mode to
indicate when the device enters the recovery mode and displays a progress indicator until the device exits the
recovery mode.
NOTE: It is recommended to use power backup solutions for all Dell systems.
Buffer I/O Error On PCIe SSD During Full Initialization
There may be I/O errors in a PCIe SSD during full initialization, while running in a Linux environment. The I/O error
messages are displayed in the operating system event log.
WARNING: To prevent data loss, do not send any I/Os to the device during full initialization.
If you are not sending any I/Os to the device, these error messages may still be displayed in the operating system event
log. These I/O error messages do not indicate an issue with the device, and have no negative effects.
