Self-Monitoring Analysis and Reporting Technology

errors

The NVMe PCIe SSD solution is always monitored for errors by its internal software. If an error occurs, it is detected and recorded in an

internal log. Based on the criticality of the error, the software may inform the host server that further action is needed. It signies that the

error condition occurred a specic number of times and that the device health needs attention.

Ungraceful system shutdown or power loss

If the host system experiences a power loss, the NVMe PCIe SSD may not have time to perform its internal shut down procedure. In such

an event, the device may enter a recovery mode.

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 device is fully accessible from the host operating system.

NOTE

: Dell recommends that you use power backup solutions for all Dell systems.

General errors

The following section describes general errors related to NVMe PCIe SSD.

Linux fails to boot and prompts for the root password

Cause

A stale volume mount point is still present after a device removal or cryptographic erase.

Solution Perform the following steps to recover from this situation:

1 Enter the root password to enter maintenance mode.

2 Remount the root lesystem as read-write using the following command: mount -orw,remount/.

3 Manually edit /etc/fstab to remove the nonexistent device entry.
