Installing the ES3000 PCIe SSD Driver

Installing the ES3000 PCIe SSD Driver

NOTE:
  • If ES3000 PCIe SSD cards are not configured, skip this chapter.
  • You can perform the procedure provided in this chapter on the CMC WebUI KVM or on PuTTY after logging in to the server. The procedure describes how to perform the procedure on PuTTY.
  1. Log in to the server as the root user.
  2. Create a softRAID array and format the SSDs.

    1. Run the lspci | grep Non-Volatile command to check whether the two ES3000 SSDs have been installed. If command output is displayed, the SSDs have been installed and can be detected by the OS.

      ES3000 SSDs can be removed or installed only when the server is powered off.

    2. Run the fdisk -l command to check the capacities of the NVMe SSDs (nvme0n1 and nvme1n1).

    3. Run the mdadm --create /dev/md100 --level=1 --raid-devices=2 /dev/nvme0n1 /dev/nvme1n1 command. When the "Continue creating array?" message is displayed, enter y and press Enter to create RAID 1 and generate the SSD space md100.
    4. Run the mkfs.xfs /dev/md100 command to format the SSD space md100.

      If data exists on the original SSDs, ensure that the data is not wanted and run the mkfs.xfs -f /dev/md100 command to format the SSDs.

  3. Mount the SSDs.

    1. Run the mkdir /hana/log command to create a log directory.
    2. Run the ls -l /hana/ command to view the log directory.

    3. Run the mount /dev/md100 /hana/log command to mount the SSDs.

  4. Configure automatic mounting upon startup.

    1. Run the mdadm --detail -scan command.

    2. Run the vi /etc/mdadm.conf command. Press i to enter the editing mode and add the following content to the mdadm.conf file.
      NOTE:

      The content in the line starting with ARRAY is the execution result of the previous step and varies depending on device models.

      device /dev/nvme0n1 /dev/nvme1n1
      ARRAY /dev/md100 level=raid1 num-devices=2 UUID=a8c122c3:26ccb2e7:2a4f6f95:b84cfc9b

    3. Press Esc. Run :wq and press Enter to save the configuration and exit.
    4. Run the vi /etc/rc.d/boot.local command, press i to enter the editing mode, move the cursor to the end of the file, and add the following content. Then run :wq and press Enter to save the configuration and exit.
      mdadm  -As
      mount  /dev/md100  /hana/log
