适用于采用ONTAP的Oracle Linux 9.4的NVMe-oF主机配置

贡献者

NetApp SAN主机配置支持采用非对称命名空间访问(AANA)的基于网络结构的NVMe (NVMe-oF)协议。在NVMe-oF环境中、ANA相当于iSCSI和FCP环境中的非对称逻辑单元访问(AMUA)多路径功能。ANA是使用内核NVMe多路径功能实施的。

关于此任务

对于采用ONTAP存储的Oracle Linux 9.4、NVMe-oF主机配置提供以下支持和功能。在开始配置过程之前、您还应查看已知限制。

  • 提供支持:

    • 支持基于TCP的NVMe (NVMe/TCP)以及基于光纤通道的NVMe (NVMe/FC)。本机NVMe-CLI软件包中的NetApp插件可显示NVMe/FC和NVMe/TCP命名库的ONTAP详细信息。

    • 在同一主机上同时运行NVMe和SCSI流量。例如、您可以为SCSI LUN的SCSI mpath设备配置dm-Multipath、并使用NVMe多路径在主机上配置NVMe-oF命名空间设备。

      有关支持的配置的其他详细信息、请参见 "NetApp 互操作性表工具"

  • 可用功能:

    • 从ONTAP 9.12.1开始、NVMe-oF引入了对安全带内身份验证的支持。您可以在Oracle Linux 9.4中对NVMe-oF使用安全带内身份验证

    • 默认情况下、支持为NVMe命名空间启用内核NVMe多路径、因此无需显式设置。

  • 已知限制:

    • 目前不支持使用NVMe-oF协议启动SAN。

验证软件版本

您可以使用以下过程验证支持的最低Oracle Linux 9.4软件版本。

步骤
  1. 在服务器上安装Oracle Linux 9.4 GA。安装完成后、验证您是否正在运行指定的Oracle Linux 9.4 GA内核。

    uname -r
    5.15.0-205.149.5.1.el9uek.x86_64
  2. 安装 NVMe-CLI 软件包:

    rpm -qa|grep nvme-cli
    nvme-cli-2.6-5.el9.x86_64
  3. 安装 libnvme 软件包:

    rpm -qa|grep libnvme
    libnvme-1.6-1.el9.x86_64
  4. 在Oracle Linux 9.4主机上,检查 hostnqn `/etc/nvme/hostnqn`以下位置的字符串:

    cat /etc/nvme/hostnqn
    nqn.2014-08.org.nvmexpress:uuid:9c5d23fe-21c5-472f-9aa4-dc68de0882e9
  5. 验证是否已 hostnqn 字符串与匹配 hostnqn ONTAP 阵列上对应子系统的字符串:

    vserver nvme subsystem host show -vserver vs_coexistence_149
    显示示例
    Vserver Subsystem Priority  Host NQN
    ------- --------- --------  ------------------------------------------------
    vs_coexistence_149
            nvme
                      regular   nqn.2014-08.org.nvmexpress:uuid:9c5d23fe-21c5-472f-9aa4-dc68de0882e9
            nvme_1
                      regular   nqn.2014-08.org.nvmexpress:uuid:9c5d23fe-21c5-472f-9aa4-dc68de0882e9
            nvme_2
                      regular   nqn.2014-08.org.nvmexpress:uuid:9c5d23fe-21c5-472f-9aa4-dc68de0882e9
            nvme_3
                      regular   nqn.2014-08.org.nvmexpress:uuid:9c5d23fe-21c5-472f-9aa4-dc68de0882e9
    4 entries were displayed.
    备注 如果 hostnqn`字符串不匹配、您可以使用 `vserver modify`命令更新 `hostnqn`相应ONTAP阵列子系统上的字符串、使其与主机上的字符串 `/etc/nvme/hostnqn`匹配 `hostnqn

配置 NVMe/FC

您可以使用Broadcom/Emulex FC或Marvell/Qlogic FC适配器配置NVMe/FC。对于配置有Broadcom适配器的NVMe/FC、可以启用大小为1 MB的I/O请求。

Broadcom/Emulex

为Broadcom/Emulex适配器配置NVMe/FC。

步骤
  1. 验证您使用的适配器型号是否受支持:

    1. cat /sys/class/scsi_host/host*/modelname

      LPe32002-M2
      LPe32002-M2
    2. cat /sys/class/scsi_host/host*/modeldesc

      Emulex LightPulse LPe32002-M2 2-Port 32Gb Fibre Channel Adapter

Marvell/QLogic

为Marvell/QLogic适配器配置NVMe/FC。

备注 Oracle Linux 9.4 GA内核中包含的本机内置qla2xxx驱动程序已进行了最新修复。这些修复程序对于ONTAP支持至关重要。
步骤
  1. 验证您是否正在运行受支持的适配器驱动程序和固件版本:

    cat /sys/class/fc_host/host*/symbolic_name
    QLE2872 FW:v9.15.00 DVR:v10.02.09.100-k
    QLE2872 FW:v9.15.00 DVR:v10.02.09.100-k
  2. 请验证 ql2xnvmeenable 已设置。这样、Marvell适配器便可用作NVMe/FC启动程序:

    cat /sys/module/qla2xxx/parameters/ql2xnvmeenable
    1

启用 1 MB I/O 大小(可选)

ONTAP会在"识别 控制器"数据中报告MDTS (MAX Data传输大小)为8。这意味着最大I/O请求大小最多可以为1 MB。要向Broadcom NVMe/FC主机发出大小为1 MB的I/O请求、应将参数的值 `lpfc_sg_seg_cnt`从默认值64增加 `lpfc`到256。

备注 这些步骤不适用于逻辑NVMe/FC主机。
步骤
  1. 将 `lpfc_sg_seg_cnt`参数设置为256:

    cat /etc/modprobe.d/lpfc.conf
    options lpfc lpfc_sg_seg_cnt=256
  2. 运行 `dracut -f`命令并重新启动主机。

  3. 验证的预期值是否 `lpfc_sg_seg_cnt`为256:

    cat /sys/module/lpfc/parameters/lpfc_sg_seg_cnt

配置 NVMe/TCP

NVMe/TCP协议不支持此 auto-connect`操作。相反、您可以通过手动执行NVMe/TCP或 `connect-all`操作来发现NVMe/TCP子系统和命名路径 `connect

步骤
  1. 验证启动程序端口是否可以通过受支持的NVMe/TCP LIF提取发现日志页面数据:

    nvme discover -t tcp -w host-traddr -a traddr
    显示示例
    nvme discover -t tcp -w 192.168.166.4 -a 192.168.166.56
    
    Discovery Log Number of Records 10, Generation counter 15

    traddr:  192.168.165.56
    eflags:  none
    sectype: none
  2. 验证其他NVMe/TCP启动程序-目标LIF组合是否可以成功提取发现日志页面数据:

    nvme discover -t tcp -w host-traddr -a traddr
    nvme discover -t tcp -w 192.168.166.4 -a 192.168.166.56
    nvme discover -t tcp -w 192.168.165.3 -a 192.168.165.56
  3. 运行 nvme connect-all 在节点中所有受支持的NVMe/TCP启动程序-目标SIP上运行命令:

    nvme connect-all -t tcp -w host-traddr -a traddr
    nvme connect-all -t tcp -w 192.168.166.4 -a 192.168.166.56
    nvme connect-all -t tcp -w 192.168.165.3 -a 192.168.165.56
    备注 从Oracle Linux 9.4开始、NVMe/TCP的默认设置 ctrl_loss_tmo timeout`已关闭、并且对重试次数没有限制(无限期重试)。使用或 `nvme connect-all`命令(选项-l)时,您不必手动配置特定的 `ctrl_loss_tmo timeout`持续时间 `nvme connect。通过此默认行为、NVMe/TCP控制器在发生路径故障时不会发生超时、并会无限期保持连接。

验证 NVMe-oF

要支持ONTAP LUN正确运行、请验证内核NVMe多路径状态、ANA状态和ONTAP命名空间是否适用于NVMe-oF配置。

步骤
  1. 在Oracle Linux 9.4主机上验证以下NVMe/FC设置:

    1. cat /sys/module/nvme_core/parameters/multipath

      Y
    2. cat /sys/class/nvme-subsystem/nvme-subsys*/model

      NetApp ONTAP Controller
      NetApp ONTAP Controller
    3. cat /sys/class/nvme-subsystem/nvme-subsys*/iopolicy

      round-robin
      round-robin
  2. 验证是否已在主机上创建并正确发现命名空间:

设置安全带内身份验证

从ONTAP 9.12.1开始、Oracle Linux 9.4主机与ONTAP控制器之间可通过NVMe/TCP和NVMe/FC进行安全带内身份验证。

要设置安全身份验证、每个主机或控制器都必须与关联 DH-HMAC-CHAP 密钥、它是NVMe主机或控制器的NQN与管理员配置的身份验证密钥的组合。要对其对等方进行身份验证、NVMe主机或控制器必须识别与对等方关联的密钥。

您可以使用命令行界面或Config JSON文件设置安全带内身份验证。如果需要为不同的子系统指定不同的dhchap密钥、则必须使用config JSON文件。

命令行界面

使用命令行界面设置安全带内身份验证。

步骤
  1. 获取主机NQN:

    cat /etc/nvme/hostnqn
  2. 为OL 9.4主机生成dhchap密钥。

    以下输出说明了 `gen-dhchap-key`命令参数:

    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

    在以下示例中、将生成一个随机dhchap密钥、其中HMAC设置为3 (SHA-512)。

    # nvme gen-dhchap-key -m 3 -n nqn.2014-08.org.nvmexpress:uuid:9796c1ec-0d34-11eb-b6b2-3a68dd3bab57
    DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:
  3. 在ONTAP控制器上、添加主机并指定两个dhchap密钥:

    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. 主机支持两种类型的身份验证方法:单向和双向。在主机上、连接到ONTAP控制器并根据所选身份验证方法指定dhchap密钥:

    nvme connect -t tcp -w <host-traddr> -a <tr-addr> -n <host_nqn> -S <authentication_host_secret> -C <authentication_controller_secret>
  5. 验证 nvme connect authentication 命令、验证主机和控制器dhchap密钥:

    1. 验证主机dhchap密钥:

      cat /sys/class/nvme-subsystem/<nvme-subsysX>/nvme*/dhchap_secret
      显示单向配置的示例输出
      cat /sys/class/nvme-subsystem/nvme-subsys0/nvme*/dhchap_secret
      DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak/G2XjgJpKZeK:
      DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak/G2XjgJpKZeK:
    2. 验证控制器dhchap密钥:

      cat /sys/class/nvme-subsystem/<nvme-subsysX>/nvme*/dhchap_ctrl_secret
      显示双向配置的示例输出
      cat /sys/class/nvme-subsystem/nvme-subsys0/nvme*/dhchap_ctrl_secret
      DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:
      DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:
JSON 文件

如果ONTAP控制器配置中有多个NVMe子系统、则可以将文件与命令结合 nvme connect-all`使用 `/etc/nvme/config.json

要生成JSON文件、可以使用 `-o`选项。有关更多语法选项、请参见NVMe Connect-all手册页。

步骤
  1. 配置 JSON 文件:

    显示示例
    cat /etc/nvme/config.json
    [
      {
        "hostnqn":"nqn.2014-08.org.nvmexpress:uuid:9796c1ec-0d34-11eb-b6b2-3a68dd3bab57",
        "hostid":"9796c1ec-0d34-11eb-b6b2-3a68dd3bab57",
        "dhchap_key":"DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak\/G2XjgJpKZeK:",
        "subsystems":[
          {
            "nqn":"nqn.1992-08.com.netapp:sn.cf84a53c81b111ef8446d039ea9ea481:subsystem.nvme_tcp_1",
            "ports":[
              {
                "transport":"tcp",
                "traddr":"192.168.165.56",
                "host_traddr":"192.168.165.3",
                "trsvcid":"4420",
                "dhchap_key":"DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak\/G2XjgJpKZeK:",
                "dhchap_ctrl_key":"DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM\/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:"
              },
              {
                "transport":"tcp",
                "traddr":"192.168.166.56",
                "host_traddr":"192.168.166.4",
                "trsvcid":"4420",
                "dhchap_key":"DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak\/G2XjgJpKZeK:",
                "dhchap_ctrl_key":"DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM\/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:"
              }
            ]
          }
        ]
      }
    ]
    备注 在上述示例中, dhchap_key`对应于, `dhchap_ctrl_key`对应 `dhchap_ctrl_secret`于 `dhchap_secret
  2. 使用config JSON文件连接到ONTAP控制器:

    nvme connect-all -J /etc/nvme/config.json
    显示示例
    traddr=192.168.165.56 is already connected
    traddr=192.168.165.56 is already connected
    traddr=192.168.165.56 is already connected
    traddr=192.168.165.56 is already connected
    traddr=192.168.165.56 is already connected
    traddr=192.168.165.56 is already connected
    traddr=192.168.166.56 is already connected
    traddr=192.168.166.56 is already connected
    traddr=192.168.166.56 is already connected
    traddr=192.168.166.56 is already connected
    traddr=192.168.166.56 is already connected
    traddr=192.168.166.56 is already connected
  3. 验证是否已为每个子系统的相应控制器启用dhchap密码:

    1. 验证主机dhchap密钥:

      cat /sys/class/nvme-subsystem/nvme-subsys0/nvme0/dhchap_secret
      DHHC-1:01:OKIc4l+fs+fmpAj0hMK7ay8tTIzjccUWSCak/G2XjgJpKZeK:
    2. 验证控制器dhchap密钥:

      cat /sys/class/nvme-subsystem/nvme-subsys0/nvme0/dhchap_ctrl_secret
      DHHC-1:03:zSq3+upTmknih8+6Ro0yw6KBQNAXjHFrOxQJaE5i916YdM/xsUSTdLkHw2MMmdFuGEslj6+LhNdf5HF0qfroFPgoQpU=:
