Installing or upgrading NVMe PCIe SSD driver for Red Hat Enterprise Linux or SUSE Linux Enterprise Server

  • NOTE: Use the procedures in this section to install or upgrade the driver for Linux. The driver is updated frequently. To ensure that you have the current version of the driver, download the latest Linux driver from Dell.com/support. For more information, see Downloading NVMe PCIe SSD drivers .
  • NOTE: Starting with RHEL 7.2 and SLES 12 SP1, there is a fully supported in-box driver. Earlier operating systems that may have an in-box driver are not supported. Dell recommends that you download the latest drivers from Dell.com/support. For more information, see Downloading NVMe PCIe SSD drivers .

SUSE Linux Enterprise Server 11 and 12 drivers are provided in the Kernel Module Package (KMP) format while Red Hat Enterprise Linux 6 drivers are provided in the Kernel Module Loader (KMOD) format. KMODs are Red Hat Packet Manager (RPM)s and are driver packaging methods that contain kernel modules, instituted to better handle kernel update situations. To install or update the NVMe PCIe SSD driver:

  1. For SLES, download the SUSE GPG Public key from the SUSE website and import by using the command #rpm –import <GPG public key> .
  2. Uncompress the zipped tarball driver release package.
  3. Install the driver package using the command: rpm -ihv < driver rpm package name >.rpm
    • NOTE: Use rpm -Uvh <package name> when updating an existing package.
  4. Restart the system for the driver update to take effect.
  5. After the system restarts, verify that the driver has been installed with the system command: # modinfo nvme The version shown in the output must match with the version of the package.
  6. Verify that the driver has been loaded with the system command: # lsmod | grep nvme or # cat /proc/modules | grep nvme These commands return nvme if the driver is loaded. The NVMe PCIe SSDs are ready for use. See Configuring NVMe PCIe SSD adapter in different operating systems .
