xDoctor 報告以下警告，指出其中一個 ECS 介面已關閉：

Displaying xDoctor Report (2017-09-01_064438) Filter:['CRITICAL', 'ERROR', 'WARNING'] ...

Timestamp    = 2017-09-01_064438
    Category = platform
    Source   = ip show
    Severity = WARNING
    Node     = 169.254.1.1
    Message  = One or more network interfaces are down or missing
    Extra    = {'1xx.2xx.1.4': ['slave-0']}

檢查叢集上的介面連結狀態。在下面的示例中，節點 4 具有 NO-CARRIER，這意味著沒有連接到 secondary-0 介面。

命令：

# viprexec -i 'ip link show | egrep "slave-|public"'

範例：

admin@node1:~> viprexec -i 'ip link show | egrep "slave-|public"'

確認個別介面偵測到連結：

命令：

# viprexec -i "echo slave-0;sudo ethtool slave-0 | grep 'Link detected:';echo slave-1;sudo ethtool slave-1 | grep 'Link detected:'"

範例：

admin@node1:~> viprexec -i "echo slave-0;sudo ethtool slave-0 | grep 'Link detected:';echo slave-1;sudo ethtool slave-1 | grep 'Link detected:'"

Output from host : 1xx.1xx.219.1
slave-0
        Link detected: yes
slave-1
        Link detected: yes

Output from host : 1xx.1xx.219.2
slave-0
        Link detected: yes
slave-1
        Link detected: yes

Output from host : 1xx.1xx.219.3
slave-0
        Link detected: yes
slave-1
        Link detected: yes

Output from host : 1xx.1xx.219.4
slave-0
        Link detected: no
slave-1
        Link detected: yes

確認交換器在第 1 代或第 2 代環境中為 Arista，以及在第 3 代環境中為 Dell （或其他型號）。

注意：如果交換器不是 Arista 或 Dell 交換器，則它們是使用者管理的交換器。我們必須通知使用者他們有連線中斷以進行補救。

檢查節點上公用介面組態的 secondary-0 和 secondary -1 的公用繫結，顯示步驟 2 中的命令未偵測到任何連結：

命令：

# sudo cat /etc/sysconfig/network/ifcfg-public

範例：

admin@node4:~> sudo cat /etc/sysconfig/network/ifcfg-public
BONDING_MASTER=yes
BONDING_MODULE_OPTS="miimon=100 mode=4 xmit_hash_policy=layer3+4"
BONDING_SLAVE0=slave-0
BONDING_SLAVE1=slave-1
BOOTPROTO=static
IPADDR=xxx.xxx.xxx.xxx/xx
MTU=1500
STARTMODE=auto

確認已在節點上設定正確的連結聚合控制通訊協定（LACP）參數。（IEEE 802.3ad 動態連結聚合是預設設定，也是預期設定。）

命令：

# viprexec -i "grep Mode /proc/net/bonding/public"

範例：

admin@node1:~> viprexec -i "grep Mode /proc/net/bonding/public"

Output from host : 1xx.1xx.219.1
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.2
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.3
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

Output from host : 1xx.1xx.219.4
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

執行下列步驟，確認連接埠的連線一致，且介面已連接：

ECS Gen 1 或 Gen 2：

節點的第一代或第二代 ECS 對應如下，對應至對應的交換器連接埠：

乙太網 9 = 節點 1
乙太網 10 = 節點 2
乙太網 11 = 節點 3
乙太網 12 = 節點 4
乙太網 13 = 節點 5
乙太網 14 = 節點 6
乙太網 15 = 節點 7
乙太網 16 = 節點 8

命令：

# viprexec -i "sudo lldpcli show neigh | egrep 'SysName|PortID'"

範例：

（第一代或第二代 ECS 的範例）

admin@ecssh121:~> viprexec -i "sudo lldpcli show neigh | egrep 'SysName|PortID'"                                                                                                                                                     
Output from host : 1xx.1xx.219.1
    SysName:      rabbit
    PortID:       ifname Ethernet9
    SysName:      hare
    PortID:       ifname Ethernet9
    SysName:      turtle
    PortID:       ifname Ethernet1

Output from host : 1xx.1xx.219.2
    SysName:      rabbit
    PortID:       ifname Ethernet10
    SysName:      hare
    PortID:       ifname Ethernet10
    SysName:      turtle
    PortID:       ifname Ethernet2

    SysName:      hare
    PortID:       ifname Ethernet11
    SysName:      rabbit
    PortID:       ifname Ethernet11
    SysName:      turtle
    PortID:       ifname Ethernet3

Output from host : 1xx.1xx.219.4
    SysName:      hare
    PortID:       ifname Ethernet12
    SysName:      turtle
    PortID:       ifname Ethernet4

注意：在上述範例中，節點 4 遺失與 Ethernet12 rabbit 的連線。透過目前收集的所有資訊，我們現在知道連接埠 12 位於 rabbit 交換器上連接到節點 4 的 secondary-0 介面

ECS Gen 3：
節點的第三代 ECS 對應如下，對應至對應的交換器連接埠：

乙太網 1/1/1 = 節點 1 乙太網 1/1/2 = 節點 2
乙太網 1/1/3 = 節點 3
乙太網 1/1/4 = 節點 4
乙太網 1/1/5 = 節點 5
乙太網 1/1/6 = 節點 6
乙太網 1/1/7 = 節點 7
乙太網 1/1
/8 = 節點 8

確認連線至四個 ECS Gen 3 交換器前端兔和野兔後端狐狸和獵犬的 ECS 連線已開啟。

檢查可能的網路介面卡問題：
另一個元件，用以檢查受影響節點上最近的 NIC 節點上的節點訊息緩衝區（dmesg）是否有最近的 NIC 問題。在以下範例中，NIC 會在處於開啟和關閉狀態之間迴圈。

如果 dmesg 中有 NIC 警示，則可能需要更換。

如果 ECS Gen 1 或 Gen 2 - 提供輸出給 ECS 支援硬體工程師進行分析。
如果是 ECS Gen 3 - 將輸出提供給會成為 EX 系列硬體專家的 Dell 硬體團隊。

命令：

# sudo dmesg -T

Cause

此問題的可能原因：

有時，小型可插拔（SFP）在安裝階段未正確安裝。
使用者管理的交換器，是在控制之外進行變更（在維護使用者管理的交換器的情況下，例如韌體升級，連結可能會中斷，並可能重新協商，如下方解決方案部分所示。）
彈性雲端伺服器硬體故障：
- 網路介面卡
- 網路纜線
- 小型可插拔（SFP）
- 網路交換器或交換器連接埠

Resolution

做任何工作
之前在使用者管理的交換器得到維護的情況下（例如韌體升級），連結可能會中斷，並可能重新協商。以下範例適用於使用者在使用者管理的 FE 交換器上完成韌體升級後的 secondary-0 關閉。以下命令用於重新協商介面：

注意：如果介面仍然故障且無法重新協商，則必須有 Dell 代表到場檢查並重新安裝 SPF 和纜線。如果這樣做無法解決，建議更換從交換器至節點的 SFP 和纜線連線。

有不同的 SFP 機型使用銅線或光纖。此外，後端和前端交換器可能使用不同類型的 SFP 電線。在更換零件之前，請先確認需要哪一個零件。

網路佈線
網路佈線圖適用於 Dell 或客戶提供機架中的 U 系列、D 系列或 C 系列 ECS 應用裝置。

為了區分這三個交換器，每個交換器都有一個暱稱：

野兔：10 GbE 公用交換器位於 U 系列或 D 系列的機架頂端，或是 C 系列段的頂端交換器。
兔子：10 GbE 公用交換器位於 U 系列或 D 系列機架頂端的 Hare 下方，或 C 系列網段中 Hare 交換器的下方。
海龜：1 GbE 專用交換器，位於 U 系列機架頂端的 rabbit 下方，或是 C 系列網段的 hare 交換器下方。

U 系列和 D 系列網路佈線
下圖顯示由 Dell 或客戶設定之 U 系列或 D 系列 ECS 之八節點機架組態的簡化網路佈線圖。在此圖之後，其他詳細圖和表格提供了埠、標籤和電纜顏色資訊。

請參閱下表以瞭解交換器和連接埠的配對資訊，以及適當的交換器連接埠號碼

。交換器 1 = Rabbit = 底部交換器交換器 2 = Hare = 頂部交換器

節點連接埠：
次要-0 = P01 = 右連接埠 - 連接到交換器 1/Rabbit/底部交換器。
次要 1 = P02 = 左側連接埠 - 連接到交換器 2/Hare/Top 交換器。
