This will go over in detail where resets are needed, the concept of firmware slots – some NVMe SSDs can have multiple copies of firmware on the device and you can activate a specific copy to run.

Instead of describing the process here, please visit section 8.1 of the NVMe 1.4 spec Firmware Update Process.
Ask your SSD vendor for the latest firmware version. An OEM generally handles firmware updates with their management tools and cryptographically signed firmware images that match the OEM, but NVMe SSDs obtained with generic firmware from a channel partner or distributor can be updated. Firmware updates ensure the most up to date security patches, bug fixes, and reliability improvements.
It is not uncommon to see four to five updates during a five year deployment of an SSD. SSD vendors will typically release new firmware over the production period of the SSD. Look for output where error count does not equal 1 to find out if there are any errors in the error log.

The output will have abbreviations for the various fields, for instance, Model Number (MN) is displayed in NVMe-CLI as mn: You will see a lot of examples in this overview of the nvme-cli command and the table in the spec that details the options on a command. The man page should be referenced though for command structure within NVMe-CLI, which will hopefully be being continually updated and can be found here.įor instance, in section 5.15.3 Identify Controller data structure, you can send the command nvme-id-ctrl in NVMe-CLI.

The man page or -help is not enough for understanding the capabilities of NVMe-CLI, but the good news is all the commands are written directly to match the spec! All you need to do is download a copy of the latest NVMe 1.4 specification to be able to interpret the abbreviations for the various commands. You can learn about why SSDs fail and why NVMe technology monitoring, management, error reporting, and logging are so important in my recent blog post. It supports NVMe SSDs as well as NVMe™ over Fabrics (NVMe-oF™) architecture and offers optional vendor plugins for supplemental information above and beyond the specification. NVMe-CLI is an open source, powerful feature set that follows the NVMe specification and is supported by all major distributions. The tool to manage NVMe SSDs in Linux is called NVMe Command Line Interface (NVMe-CLI).ĭata centers require many management functions to monitor the health of the SSD, monitor endurance, update firmware, securely erase storage and read various logs. NVM Express™ (NVMe™) technology has enabled a robust set of industry-standard software, drivers, and management tools that have been developed for storage.
