适用于采用ONTAP的SUSE Linux Enterprise Server 15 SP6的NVMe-oF主机配置

贡献者

具有非对称命名空间访问(AANA)的SUSE Linux Enterprise Server 15 SP6支持基于网络结构的NVMe (NVMe-oF)、包括基于光纤通道的NVMe (NVMe/FC)和其他传输。在NVMe-oF环境中、ANA相当于iSCSI和FCP环境中的ALUA多路径功能、并可通过内核NVMe多路径实施。

以下支持适用于采用ONTAP的SUSE Linux Enterprise Server 15 SP6的NVMe-oF主机配置：

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

  • 支持基于TCP的NVMe (NVMe/TCP)和NVMe/FC。这样、本机软件包中的NetApp插件 `nvme-cli`就能够显示NVMe/FC和NVMe/TCP命名区的ONTAP详细信息。

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"。

功能

  • 支持NVMe安全带内身份验证

  • 支持使用唯一发现NQN的永久性发现控制器(PDC)

  • 为NVMe/TCP提供TLS 1.3加密支持

已知限制

  • 目前不支持使用NVMe-oF协议启动SAN。

  • 在SUSE Linux Enterprise Server 15 SP6主机上、NetApp `sanlun`主机实用程序不支持NVMe-oF。而是可以依赖本机软件包中的NetApp插件 `nvme-cli`进行所有NVMe-oF传输。

配置 NVMe/FC

您可以为采用ONTAP配置的SUSE Linux Enterprise Server 15 SP6配置NVMe/FC与Broadcom/Emulex FC或Marvell/Qlogic FC适配器。

Broadcom/Emulex

为Broadcom/Emulex FC适配器配置NVMe/FC。

步骤

  1. 确认您使用的是建议的适配器型号：

    cat /sys/class/scsi_host/host*/modelname
    示例输出
    LPe32002 M2
LPe32002-M2

  2. 验证适配器型号问题描述：

    cat /sys/class/scsi_host/host*/modeldesc
    示例输出
    Emulex LightPulse LPe32002-M2 2-Port 32Gb Fibre Channel Adapter
Emulex LightPulse LPe32002-M2 2-Port 32Gb Fibre Channel Adapter

  3. 验证是否正在使用建议的Emulex主机总线适配器(HBA)固件版本：

    cat /sys/class/scsi_host/host*/fwrev
    示例输出
    14.2.673.40, sli-4:2:c
14.2.673.40, sli-4:2:c

  4. 验证是否正在使用建议的lpfc驱动程序版本：

    cat /sys/module/lpfc/version
    示例输出
    0:14.4.0.1

  5. 验证是否可以查看启动程序端口：

    cat /sys/class/fc_host/host*/port_name
    示例输出
    0x10000090fae0ec88
0x10000090fae0ec89

  6. 验证启动程序端口是否联机：

    cat /sys/class/fc_host/host*/port_state
    示例输出
    Online
Online

  7. 验证NVMe/FC启动程序端口是否已启用且目标端口是否可见：

    cat /sys/class/scsi_host/host*/nvme_info

    在以下示例中、一个启动程序端口已启用、并与两个目标生命周期关联。

Marvell/QLogic

SUSE Linux Enterprise Server 15 SP6内核中附带的本机内置qla2xxx驱动程序具有最新的修复程序。这些修复程序对于ONTAP支持至关重要。

为Marvell/QLogic适配器配置NVMe/FC。

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
    示例输出
    QLE2742 FW:v9.14.01 DVR: v10.02.09.200-k
QLE2742 FW:v9.14.01 DVR: v10.02.09.200-k

  2. 验证是否已 ql2xnvmeenable 参数设置为1：

    cat /sys/module/qla2xxx/parameters/ql2xnvmeenable

    预期值为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

验证NVMe服务

从SUSE Linux Enterprise Server 15 SP6开始、 `nvmefc-boot-connections.service`NVMe/FC包中包含的和 `nvmf-autoconnect.service`启动服务 `nvme-cli`会自动启用、以便在系统启动期间启动。系统启动完成后、您应验证是否已启用启动服务。

步骤

  1. 验证是否 `nvmf-autoconnect.service`已启用：

    # systemctl status nvmf-autoconnect.service

    显示示例输出 
    nvmf-autoconnect.service - Connect NVMe-oF subsystems automatically during boot
  Loaded: loaded (/usr/lib/systemd/system/nvmf-autoconnect.service; enabled; vendor preset: disabled)
  Active: inactive (dead) since Thu 2024-05-25 14:55:00 IST; 11min ago

systemd[1]: nvmf-autoconnect.service: Deactivated successfully.
systemd[1]: Finished Connect NVMe-oF subsystems automatically during boot.

  2. 验证是否 `nvmefc-boot-connections.service`已启用：

    # systemctl status nvmefc-boot-connections.service

    显示示例输出 
    nvmefc-boot-connections.service - Auto-connect to subsystems on FC-NVME devices found during boot
   Loaded: loaded (/usr/lib/systemd/system/nvmefc-boot-connections.service; enabled; vendor preset: enabled)
   Active: inactive (dead) since Thu 2024-05-25 14:55:00 IST; 11min ago

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

配置 NVMe/TCP

NVMe/TCP没有自动连接功能。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>
    显示示例输出 
    Discovery Log Number of Records 8, Generation counter 18

  2. 验证所有其他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>
    示例输出
    #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. 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>
    示例输出
    # 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
    备注 从SUSE Linux Enterprise Server 15 SP6开始、NVMe/TCP超时的默认设置 ctrl-loss-tmo`已关闭。这意味着重试次数没有限制(无限期重试)，使用或 `nvme connect-all`命令(选项 `-l)时无需手动配置特定的 `ctrl-loss-tmo`超时持续时间。 `nvme connect`此外、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

使用以下过程验证采用ONTAP的SUSE Linux Enterprise Server 15 SP6的NVMe-oF配置。

步骤

  1. 验证是否已启用内核 NVMe 多路径：

    cat /sys/module/nvme_core/parameters/multipath

    预期值为"Y"。

  2. 验证主机是否具有适用于ONTAP NVMe命名卷的正确控制器型号：

    cat /sys/class/nvme-subsystem/nvme-subsys*/model
    示例输出
    NetApp ONTAP Controller
NetApp ONTAP Controller

  3. 验证相应ONTAP NVMe I/O控制器的NVMe I/O策略：

    cat /sys/class/nvme-subsystem/nvme-subsys*/iopolicy
    示例输出
    round-robin
round-robin

  4. 验证ONTAP名称卷是否对主机可见：

    nvme list -v
    显示示例输出 
    Subsystem        Subsystem-NQN                                                                         Controllers

创建永久性发现控制器

从SUSEL.11.1开始、您可以为ONTAP 9 15 SP6主机创建永久性发现控制器(PDC)。要自动检测NVMe子系统添加或删除操作以及对发现日志页面数据的更改、需要PDC。

步骤

  1. 验证发现日志页面数据是否可用、并且可以通过启动程序端口和目标LIF组合进行检索：

    nvme discover -t <trtype> -w <host-traddr> -a <traddr>
    显示示例输出

设置安全带内身份验证

从Linux.12.1开始、支持在ONTAP 9 15 SP6主机和ONTAP控制器之间通过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SUSE Linux Enterprise Server 15 SP6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:d3ca725a- ac8d-4d88-b46a-174ac235139b

  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-subsys1/nvme*/dhchap_secret

    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-subsys6/nvme*/dhchap_ctrl_secret

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：

配置传输层安全性

传输层安全(Transport Layer Security、TLS)可为NVMe-oF主机和ONTAP阵列之间的NVMe连接提供安全的端到端加密。从tls.16.1开始、您可以使用ONTAP 9和已配置的预共享密钥(PSK)配置tls.1.3。

关于此任务

您可以在SUSE Linux Enterprise Server 15 SP6主机上执行此过程中的步骤、但指定您在ONTAP控制器上执行某个步骤的情况除外。

步骤

  1. 检查主机上是否安装了以下ktls-utils、opensl和libopenssl软件包：

    1. rpm -qa | grep ktls

      示例输出
      ktls-utils-0.10+12.gc3923f7-150600.1.2.x86_64

    2. rpm -qa | grep ssl

      示例输出
      openssl-3-3.1.4-150600.5.7.1.x86_64
libopenssl1_1-1.1.1w-150600.5.3.1.x86_64
libopenssl3-3.1.4-150600.5.7.1.x86_64

  2. 验证是否已正确设置 /etc/tlshd.conf：

    # cat /etc/tlshd.conf
    显示示例输出 
    [debug]
loglevel=0
tls=0
nl=0
[authenticate]
keyrings=.nvme
[authenticate.client]
#x509.truststore= <pathname>
#x509.certificate= <pathname>
#x509.private_key= <pathname>
[authenticate.server]
#x509.truststore= <pathname>
#x509.certificate= <pathname>
#x509.private_key= <pathname>

  3. 启用 `tlshd`以在系统启动时启动：

    # systemctl enable tlshd

  4. 验证守护进程是否 `tlshd`正在运行：

    # systemctl status tlshd
    显示示例输出 
    tlshd.service - Handshake service for kernel TLS consumers

  5. 使用生成TLS PSK nvme gen-tls-key：

    1. # cat /etc/nvme/hostnqn

      示例输出
      nqn.2014-08.org.nvmexpress:uuid:e58eca24-faff-11ea-8fee-3a68dd3b5c5f

    2. # nvme gen-tls-key --hmac=1 --identity=1 --subsysnqn=nqn.1992-08.com.netapp:sn.1d59a6b2416b11ef9ed5d039ea50acb3:subsystem.sles15

      示例输出
      NVMeTLSkey-1:01:dNcby017axByCko8GivzOO9zGlgHDXJCN6KLzvYoA+NpT1uD:

  6. 在ONTAP控制器上、将TLS PSK添加到ONTAP子系统：

    # 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. 将TLS PSK插入主机内核密钥环：

    # 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
    示例输出
    Inserted TLS key 22152a7e
    备注 PSK显示为"NVMe1R01"、因为它使用TLS握手算法中的"Identity v1"。Identity v1是ONTAP唯一支持的版本。

  8. 验证是否已正确插入TLS PSK：

    # cat /proc/keys | grep NVMe
    示例输出
    22152a7e I--Q---     1 perm 3b010000     0     0 psk       NVMe1R01 nqn.2014-08.org.nvmexpress:uuid:ffa0c815-e28b-4bb1-8d4c-7c6d5e610bfc nqn.1992-08.com.netapp:sn.1d59a6b2416b11ef9ed5d039ea50acb3:subsystem.sles15 UoP9dEfvuCUzzpS0DYxnshKDapZYmvA0/RJJ8JAqmAo=: 32

  9. 使用插入的TLS PSK连接到ONTAP子系统：

    1. # nvme connect -t tcp -w 20.20.10.80 -a 20.20.10.14 -n nqn.1992-08.com.netapp:sn.1d59a6b2416b11ef9ed5d039ea50acb3:subsystem.sles15 --tls_key=0x22152a7e --tls

      示例输出
