適用於 ONTAP 的 SUSE Linux Enterprise Server 15 SP6 的 NVMe 主機組態

貢獻者

含非對稱命名空間存取( ANA )的 SUSE Linux Enterprise Server 15 SP6 支援 NVMe over Fabrics ( NVMe over Fabric , NVMe of ),包括 NVMe over Fibre Channel ( NVMe / FC )和其他傳輸。在 NVMe 環境中、 ANA 等同於 iSCSI 和 FCP 環境中的 ALUA 多重路徑、並以核心內建 NVMe 多重路徑來實作。

以下支援適用於採用 ONTAP 的 SUSE Linux Enterprise Server 15 SP6 的 NVMe 主機組態:

  • 在同一個共存的主機上執行 NVMe 和 SCSI 流量。例如,您可以為 SCSI LUN 的 SCSI 裝置設定 dm-multipath mpath ,並使用 NVMe 多重路徑在主機上設定 NVMe 命名空間裝置。

  • 支援 NVMe over TCP ( NVMe / TCP )和 NVMe / FC 。這讓原生套件中的 NetApp 外掛程式 `nvme-cli`能夠同時顯示 NVMe / FC 和 NVMe / TCP 命名空間的 ONTAP 詳細資料。

如需支援組態的詳細資訊、請參閱 "NetApp 互通性對照表工具"

功能

  • 支援 NVMe 安全頻內驗證

  • 使用獨特的探索 NQN 支援持續探索控制器( PDC )

  • 支援 NVMe / TCP 的 TLS 1.3 加密

已知限制

  • 目前不支援使用 NVMe 型傳輸協定進行 SAN 開機。

  • 在 SUSE Linux Enterprise Server 15 SP6 主機上, NetApp sanlun 主機公用程式不支援 NVMe 型。您可以改用原生套件中的 NetApp 外掛程式 `nvme-cli`來執行所有 NVMe 傳輸。

設定NVMe/FC

您可以為採用 ONTAP 組態的 SUSE Linux Enterprise Server 15 SP6 設定使用 Broadcom/Emulex FC 或 Marvell/Qlogic FC 介面卡的 NVMe / FC 。

Broadcom / Emulex

Marvell / QLogic

SUSE Linux Enterprise Server 15 SP6 核心中隨附的原生收件匣 qla2xxx 驅動程式具有最新的修正程式。這些修正對於 ONTAP 支援至關重要。

為 Marvell/QLogic 介面卡設定 NVMe / FC 。

步驟
  1. 確認您執行的是支援的介面卡驅動程式和韌體版本:

    cat /sys/class/fc_host/host*/symbolic_name
    輸出範例
    QLE2742 FW:v9.14.01 DVR: v10.02.09.200-k
    QLE2742 FW:v9.14.01 DVR: v10.02.09.200-k
  2. 確認 ql2xnvmeenable 參數設為 1 :

    cat /sys/module/qla2xxx/parameters/ql2xnvmeenable

    預期值為 1 。

啟用1MB I/O大小(選用)

ONTAP 會在識別控制器資料中報告 8 的 MDTS ( MAX Data 傳輸大小)。這表示最大 I/O 要求大小最多可達 1MB 。若要針對 Broadcom NVMe / FC 主機發出大小為 1 MB 的 I/O 要求,您應該將參數值 `lpfc_sg_seg_cnt`從預設值 64 增加 `lpfc`至 256 。

註 這些步驟不適用於 Qlogic NVMe / FC 主機。
步驟
  1. 將 `lpfc_sg_seg_cnt`參數設定為 256 :

    cat /etc/modprobe.d/lpfc.conf
    options lpfc lpfc_sg_seg_cnt=256
  2. 執行 `dracut -f`命令,然後重新啟動主機。

  3. 確認預期值 `lpfc_sg_seg_cnt`為 256 :

    cat /sys/module/lpfc/parameters/lpfc_sg_seg_cnt

驗證 NVMe 服務

從 SUSE Linux Enterprise Server 15 SP6 開始, nvmefc-boot-connections.service NVMe / FC 套件隨附的和 `nvmf-autoconnect.service`開機服務 `nvme-cli`會在系統開機期間自動啟用。系統開機完成後,您應該確認開機服務已啟用。

步驟
  1. 確認 `nvmf-autoconnect.service`已啟用:

    # systemctl status nvmf-autoconnect.service

    顯示範例輸出
    nvmf-autoconnect.service - Connect NVMe-oF subsystems automatically during boot
      Loaded: loaded (/usr/lib/systemd/system/nvmf-autoconnect.service; enabled; vendor preset: disabled)

    systemd[1]: nvmf-autoconnect.service: Deactivated successfully.
    systemd[1]: Finished Connect NVMe-oF subsystems automatically during boot.
  2. 確認 `nvmefc-boot-connections.service`已啟用:

    # systemctl status nvmefc-boot-connections.service

    顯示範例輸出
    nvmefc-boot-connections.service - Auto-connect to subsystems on FC-NVME devices found during boot

    systemd[1]: nvmefc-boot-connections.service: Succeeded.
    systemd[1]: Finished Auto-connect to subsystems on FC-NVME devices found during boot.

設定NVMe/TCP

NVMe / TCP 沒有自動連線功能。您可以改為透過手動執行 NVMe / TCP 或 connect-all`作業來探索 NVMe / TCP 子系統和命名空間 `connect

步驟
  1. 確認啟動器連接埠可在支援的NVMe/TCP LIF中擷取探索記錄頁面資料:

    nvme discover -t tcp -w <host-traddr> -a <traddr>
    顯示範例輸出

  2. 確認所有其他的 NVMe / TCP 啟動器目標 LIF 組合都能成功擷取探索記錄頁面資料:

    nvme discover -t tcp -w <host-traddr> -a <traddr>
    輸出範例
    #nvme discover -t tcp -w 192.168.111.79 -a 192.168.111.66
    #nvme discover -t tcp -w 192.168.111.79 -a 192.168.111.67
    #nvme discover -t tcp -w 192.168.211.79 -a 192.168.211.66
    #nvme discover -t tcp -w 192.168.211.79 -a 192.168.211.67
  3. 執行 nvme connect-all 跨所有節點支援的 NVMe / TCP 啟動器目標生命體執行命令:

    nvme connect-all -t tcp -w <host-traddr> -a <traddr>
    輸出範例
    # nvme connect-all -t tcp -w 192.168.111.79 -a 192.168.111.66
    # nvme connect-all -t tcp -w 192.168.111.79 -a 192.168.111.67
    # nvme connect-all -t tcp -w 192.168.211.79 -a 192.168.211.66
    # nvme connect-all -t tcp -w 192.168.211.79 -a 192.168.211.67
    註 從 SUSE Linux Enterprise Server 15 SP6 開始、 NVMe / TCP 逾時的預設設定 ctrl-loss-tmo`就會關閉。這表示重試次數沒有限制(無限期重試),而且您不需要在使用或 `nvme connect-all`命令(選項 `-l)時手動設定特定的 ctrl-loss-tmo`逾時時間 `nvme connect。此外、在發生路徑故障時、 NVMe / TCP 控制器不會發生逾時、也不會無限期保持連線。

驗證NVMe

請使用下列程序來驗證具有 ONTAP 組態的 SUSE Linux Enterprise Server 15 SP6 的 NVMe 型。

步驟
  1. 確認已啟用核心內建 NVMe 多重路徑:

    cat /sys/module/nvme_core/parameters/multipath

    預期值為「 Y 」。

  2. 確認主機具有適用於 ONTAP NVMe 命名空間的正確控制器機型:

建立持續探索控制器

從 ONTAP 9 。 11.1 開始,您可以為 SUSE Linux Enterprise Server 15 SP6 主機建立持續探索控制器( PDC )。需要有 PDC 才能自動偵測 NVMe 子系統新增或移除作業,以及探索記錄頁面資料的變更。

步驟
  1. 確認探索記錄頁面資料可用、並可透過啟動器連接埠和目標 LIF 組合擷取:

設定安全的頻內驗證

從 ONTAP 9 。 12.1 開始,在 SUSE Linux Enterprise Server 15 SP6 主機和 ONTAP 控制器之間,透過 NVMe / TCP 和 NVMe / FC 支援安全頻內驗證。

若要設定安全驗證、每個主機或控制器都必須與相關聯 DH-HMAC-CHAP 金鑰、這是 NVMe 主機或控制器的 NQN 組合、以及管理員設定的驗證密碼。若要驗證其對等端點、 NVMe 主機或控制器必須識別與對等端點相關的金鑰。

您可以使用 CLI 或組態 JSON 檔案來設定安全的頻內驗證。如果您需要為不同的子系統指定不同的 dhchap 金鑰、則必須使用組態 JSON 檔案。

CLI

使用 CLI 設定安全的頻內驗證。

步驟
  1. 取得主機 NQN :

    cat /etc/nvme/hostnqn
  2. 為 SUSE Linux Enterprise Server 15 SP6 主機產生 dhchap 金鑰。

    下列輸出說明 `gen-dhchap-key`命令參數:

    nvme gen-dhchap-key -s optional_secret -l key_length {32|48|64} -m HMAC_function {0|1|2|3} -n host_nqn
    •	-s secret key in hexadecimal characters to be used to initialize the host key
    •	-l length of the resulting key in bytes
    •	-m HMAC function to use for key transformation
    0 = none, 1- SHA-256, 2 = SHA-384, 3=SHA-512
    •	-n host NQN to use for key transformation

    在下列範例中、會產生一個隨機的 dhchap 金鑰、其中 HMAC 設為 3 ( SHA-512 )。

    # nvme gen-dhchap-key -m 3 -n nqn.2014-08.org.nvmexpress:uuid:d3ca725a- ac8d-4d88-b46a-174ac235139b
    DHHC-1:03:J2UJQfj9f0pLnpF/ASDJRTyILKJRr5CougGpGdQSysPrLu6RW1fGl5VSjbeDF1n1DEh3nVBe19nQ/LxreSBeH/bx/pU=:
  3. 在 ONTAP 控制器上、新增主機並指定兩個 dhchap 金鑰:

    vserver nvme subsystem host add -vserver <svm_name> -subsystem <subsystem> -host-nqn <host_nqn> -dhchap-host-secret <authentication_host_secret> -dhchap-controller-secret <authentication_controller_secret> -dhchap-hash-function {sha-256|sha-512} -dhchap-group {none|2048-bit|3072-bit|4096-bit|6144-bit|8192-bit}
  4. 主機支援兩種驗證方法:單向和雙向。在主機上、連線至 ONTAP 控制器、並根據所選的驗證方法指定 dhchap 金鑰:

    nvme connect -t tcp -w <host-traddr> -a <tr-addr> -n <host_nqn> -S <authentication_host_secret> -C <authentication_controller_secret>
  5. 驗證 nvme connect authentication 命令驗證主機和控制器 dhchap 金鑰:

    1. 驗證主機 dhchap 金鑰:

      cat /sys/class/nvme-subsystem/<nvme-subsysX>/nvme*/dhchap_secret
      顯示單向組態的輸出範例
      # cat /sys/class/nvme-subsystem/nvme-subsys1/nvme*/dhchap_secret

    2. 驗證控制器 dhchap 按鍵:

      cat /sys/class/nvme-subsystem/<nvme-subsysX>/nvme*/dhchap_ctrl_secret
      顯示雙向組態的輸出範例
      # cat /sys/class/nvme-subsystem/nvme-subsys6/nvme*/dhchap_ctrl_secret

Json 檔案

當 ONTAP 控制器組態上有多個 NVMe 子系統可供使用時、您可以搭配命令使用該 /etc/nvme/config.json`檔案 `nvme connect-all

若要產生 JSON 檔案,您可以使用 `-o`選項。如需更多語法選項,請參閱 NVMe Connect All 手冊頁。

設定傳輸層安全性

傳輸層安全性( TLS )可為 NVMe 主機和 ONTAP 陣列之間的 NVMe 連線提供安全的端對端加密。從 ONTAP 9 。 16.1 開始,您可以使用 CLI 和設定的預先共用金鑰( PSK )來設定 TLS 1.3 。

關於這項工作

您可以在 SUSE Linux Enterprise Server 15 SP6 主機上執行此程序中的步驟,但指定您在 ONTAP 控制器上執行步驟的位置除外。

步驟
  1. 檢查主機上是否安裝了以下 ktls-utils , openssl 和 libopenssl 軟件包:

    1. rpm -qa | grep ktls

      輸出範例
      ktls-utils-0.10+12.gc3923f7-150600.1.2.x86_64

      libopenssl3-3.1.4-150600.5.7.1.x86_64
  2. 請確認您的設定是否正確 /etc/tlshd.conf

    # cat /etc/tlshd.conf
    顯示範例輸出
    [debug]
    loglevel=0
    tls=0

    #x509.truststore= <pathname>
    #x509.certificate= <pathname>
    #x509.private_key= <pathname>
  3. 啟用 `tlshd`以在系統開機時啟動:

    # systemctl enable tlshd
  4. 驗證守護程序是否 `tlshd`正在運行:

    # systemctl status tlshd

    # nvme subsystem host add -vserver sles15_tls -subsystem sles15 -host-nqn nqn.2014-08.org.nvmexpress:uuid:ffa0c815-e28b-4bb1-8d4c-7c6d5e610bfc -tls-configured-psk NVMeTLSkey-1:01:dNcby017axByCko8GivzOO9zGlgHDXJCN6KLzvYoA+NpT1uD:
  7. 將 TLS PSK 插入主機核心金鑰環:

    # nvme check-tls-key --identity=1 --subsysnqn=nqn.2014-08.org.nvmexpress:uuid:ffa0c815-e28b-4bb1-8d4c-7c6d5e610bf --keydata=NVMeTLSkey-1:01:dNcby017axByCko8GivzOO9zGlgHDXJCN6KLzvYoA+NpT1uD: --insert
    輸出範例
    Inserted TLS key 22152a7e
    註 PSK 顯示為「 NVMe1R01 」,因為它使用 TLS 交握演算法的「 identity v1 」。Identity v1 是 ONTAP 唯一支援的版本。
  8. 確認 TLS PSK 已正確插入:

    # cat /proc/keys | grep NVMe
    輸出範例

  10. 新增目標,並驗證 TLS 連線至指定的 ONTAP 子系統:

    # nvme subsystem controller show -vserver sles15_tls -subsystem sles15 -instance

    顯示範例輸出
