設定NVIDIA IP SN2100交換器

貢獻者
PDF

您必須設定NVIDIA SN2100 IP交換器作為叢集互連和後端MetroCluster 的SIP連線。

[Reset-the switch]將NVIDIA IP SN2100交換器重設為原廠預設值

您可以選擇下列方法、將交換器重設為原廠預設值。

使用RCF檔案選項重設交換器

在安裝新的RCF組態之前、您必須還原NVIDIA交換器設定。

關於這項工作

若要將交換器還原為預設設定、請使用「restoreDefaults」選項來執行RCF檔案。此選項會將原始備份檔案複製到原始位置、然後重新啟動交換器。重新開機之後、交換器會與您第一次執行RCF檔案來設定交換器時的原始組態一起上線。

下列組態詳細資料不會重設：

  • 使用者與認證組態

  • 管理網路連接埠eth0的組態

註 在應用RCF檔案期間發生的所有其他組態變更、都會還原為原始組態。
開始之前

  • 您必須根據設定交換器 下載並安裝NVIDIA RCF檔案。如果您尚未以這種方式設定、或是在執行RCF檔案之前已設定其他功能、則無法使用此程序。

  • 您必須在MetroCluster 各個採用EIP組態的IP交換器上重複這些步驟。

  • 您必須使用序列主控台連線連接至交換器。

  • 此工作會重設管理網路的組態。

步驟

  1. 確認RCF組態已成功套用至相同或相容的RCF檔案版本、而且備份檔案已存在。

    註 輸出內容可以顯示備份檔案、保留檔案或兩者。如果輸出中沒有出現備份檔案或保留的檔案、您就無法使用此程序。

  2. 使用選項執行RCF檔案以還原預設值：「恢復預設值」

    cumulus@IP_switch_A_1:mgmt:~$ sudo python3 MSN2100_v1.0_IP_switch_A_2.py restoreDefaults
[sudo] password for cumulus:
>>> Opened RcfApplyLog
Can restore from backup directory. Continuing.
This will reboot the switch !!!
Enter yes or no: yes

  3. 對提示回應「是」。交換器會還原為原始組態並重新開機。

  4. 等待交換器重新開機。

    交換器會重設並保留初始組態、例如管理網路組態和目前認證、然後再套用RCF檔案。重新開機之後、您可以使用相同或不同版本的RCF檔案來套用新組態。

使用Cummuls安裝選項重設交換器

關於這項工作

如果您想要套用Cummuls映像來完全重設交換器、請使用這些步驟。

開始之前

  • 您必須使用序列主控台連線連接至交換器。

  • 可透過HTTP存取Cummulis交換器軟體映像。

    註 如需安裝 Cumulus Linux 的詳細資訊、請參閱 "NVIDIA SN2100交換器的安裝與組態總覽"

  • 您必須擁有root密碼才能存取命令。

步驟

  1. 從Cummulo主控台下載交換器軟體、然後使用命令「onie-install -A -i」排入安裝佇列、接著再輸入交換器軟體的檔案路徑：

    在此範例中、會將韌體檔案「累計至Linux -4.4.2-mlx-amd64.bin」從HTTP伺服器「50.50.50」複製到本機交換器。

  5. 設定管理網路介面。

    註 以下範例說明如何使用命令設定主機名稱（ip_switch_a_1）、IP位址（10.10.10.10）、網路遮罩（255．255．255．255．0（24））和閘道（10．10．10）：「net add hostname>'、「net add interface eth0 ip address<IPAddress/mask>'、「net add interface eth0 ip gateway <gateway>」（網路新增介面eth0 IP閘道<gateway>）。

  6. 使用「show reboot"命令重新啟動交換器。

    cumulus@cumulus:~$ sudo reboot

    當交換器重新開機時、您可以使用中的步驟套用新的組態 下載並安裝NVIDIA RCF檔案。

[[Download-and -install]]下載並安裝NVIDIA RCF檔案

您必須將交換器RCF檔案下載並安裝到MetroCluster 各個交換器、以供採用此功能的介面IP組態。

開始之前

  • 您必須擁有root密碼才能存取命令。

  • 交換器軟體已安裝且管理網路已設定完成。

  • 您依照步驟、使用方法1或方法2開始安裝交換器。

  • 初始安裝之後、您並未套用任何其他組態。

    註 如果您在重設交換器之後以及套用RCF檔案之前執行進一步的組態、則無法使用此程序。
關於這項工作

您必須在MetroCluster 各個IP交換器上重複上述步驟（全新安裝）或更換交換器（更換交換器）。

步驟

  1. 產生NVIDIA RCF檔案MetroCluster 以利知識IP。

    1. 下載 "RcfFileGeneratorfor MetroCluster EfIP"。

    2. 使用RcfFileGeneratorfor MetroCluster EscIP、為您的組態產生RCF檔案。

    3. 瀏覽至您的主目錄。如果您記錄為「累計」、則檔案路徑為「home/gumulus」。

      cumulus@IP_switch_A_1:mgmt:~$ cd ~
cumulus@IP_switch_A_1:mgmt:~$ pwd
/home/cumulus
cumulus@IP_switch_A_1:mgmt:~$

    4. 將RCF檔案下載至此目錄。以下範例顯示、您可以使用scp將檔案「M f2 2100 v1.0」_ip_switch_a_1.txt’從伺服器「50、50」下載到您的主目錄、並將其儲存為「M f2 2100、v1.0、ip_switch_a_1.py」：

      cumulus@Switch-A-1:mgmt:~$ scp username@50.50.50.50:/RcfFiles/MSN2100_v1.0_IP_switch_A_1.txt ./MSN2100_v1.0_IP_switch-A1.py
The authenticity of host '50.50.50.50 (50.50.50.50)' can't be established.
RSA key fingerprint is SHA256:B5gBtOmNZvdKiY+dPhh8=ZK9DaKG7g6sv+2gFlGVF8E.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '50.50.50.50' (RSA) to the list of known hosts.

cumulus@IP_switch_A_1:mgmt:~$

  2. 執行RCF檔案。RCF檔案需要選項才能套用一或多個步驟。除非技術支援人員指示、否則請在不使用命令列選項的情況下執行RCF檔案。若要驗證RCF檔案各個步驟的完成狀態、請使用選項「-1」或「ALL」來套用所有（擱置中）步驟。

    cumulus@IP_switch_A_1:mgmt:~$ sudo python3 MSN2100_v1.0_IP_switch_A_1.py

停用未使用的 ISL 連接埠和連接埠通道

NetApp 建議停用未使用的 ISL 連接埠和連接埠通道、以避免不必要的健全狀況警示。

  1. 使用 RCF 檔案橫幅識別未使用的 ISL 連接埠和連接埠通道：

    註 如果連接埠處於中斷連線模式、則您在命令中指定的連接埠名稱可能與 RCF 橫幅中指定的名稱不同。您也可以使用 RCF 纜線檔案來尋找連接埠名稱。

    net show interface

  2. 使用 RCF 檔案停用未使用的 ISL 連接埠和連接埠通道。

    cumulus@mcc1-integrity-a1:mgmt:~$ sudo python3 SN2100_v2.0_IP_Switch-A1.py runCmd
[sudo] password for cumulus:
    Running cumulus version  : 5.4.0
    Running RCF file version : v2.0
Help for runCmd:
    To run a command execute the RCF script as follows:
    sudo python3 <script> runCmd <option-1> <option-2> <option-x>
    Depending on the command more or less options are required. Example to 'up' port 'swp1'
        sudo python3 SN2100_v2.0_IP_Switch-A1.py runCmd swp1 up
    Available commands:
        UP / DOWN the switchport
            sudo python3 SN2100_v2.0_IP_Switch-A1.py runCmd <switchport> state <up | down>
        Set the switch port speed
            sudo python3 SN2100_v2.0_Switch-A1.py runCmd <switchport> speed <10 | 25 | 40 | 100 | AN>
        Set the fec mode on the switch port
            sudo python3 SN2100_v2.0_Switch-A1.py runCmd <switchport> fec <default | auto | rs | baser | off>
        Set the [localISL | remoteISL] to 'UP' or 'DOWN' state
            sudo python3 SN2100_v2.0_Switch-A1.py runCmd [localISL | remoteISL] state [up | down]
        Set the option on the port to support DAC cables. This option does not support port ranges.
            You must reload the switch after changing this option for the required ports. This will disrupt traffic.
            This setting requires Cumulus 5.4 or a later 5.x release.
            sudo python3 SN2100_v2.0_Switch-A1.py runCmd <switchport> DacOption [enable | disable]
cumulus@mcc1-integrity-a1:mgmt:~$

    下列範例命令會停用連接埠 "swp14" ：

    sudo python3 SN2100_v2.0_Switch-A1.py runCmd swp14 state down

    針對每個識別出未使用的連接埠或連接埠通道重複此步驟。
