5.1.3 如何添加Cluster Transport Cable和传输适配器

使用以下过程从节点中移除群集传输电缆和群集传输适配器。当禁用一个电缆后,电缆的两个端点 仍处于已配置状态。如果一个适配器仍用作一个传输电缆的一个端点,则无法移除该适配器。


小心:小心:

一个群集节点要成为一个群集的成员,至少需要有一个使用中的电缆连接到 群集互连。每次禁用一个电缆前,都要检验节点的群集互连的状态。对于一个电缆连接,只有验证了它是 冗余的(即除它之外还有另外一个连接),才予以禁用。禁用节点所剩的最后一个工作电缆会使节点 脱离群集。


  1. 成为群集中任一节点上的超级用户。

  2. 检查尚存的群集传输路径的状态。


    # scstat -W
    

    小心:小心:

    如果在尝试移除由两个节点组成的群集的一个节点时接收到一个 错误(如 "path faulted"),请在继续进行此过程前调研该问题。这样一个问题可能 表明一个节点路径不可用。如果移除所剩的正常路径,则会使节点脱离群集,并可能导致群集重新配置。


  3. 执行 scsetup 公用程序。


    # scsetup
    

    出现主菜单。

  4. 通过输入 2(群集互连)访问群集互连菜单。

  5. 通过输入 4(移除一个传输电缆)移除传输电缆。

    按说明操作并输入系统请求的信息。您需要输入您尝试标识的电缆的一个端点的节点名称和适配器名称。


    *** Cluster Interconnect Menu ***
        Please select from one of the following options:
        ...
        4) Remove a transport cable
        ...
        Option: 4
        ...
    >>> Remove a Cluster Transport Cable <<<
        ...
        Is it okay to continue (yes/no) [yes]? <Return>
        ...
        To which node is the cable attached? nodename
        Name of the adapter on "node"? adaptername
        Is it okay to proceed with the update (yes/no) [yes]? <Return>
        ...
        Command completed successfully.    Hit ENTER to continue: <Return>
    

    注意:

    如果您要移除一个物理电缆,请断开端口与目标设备之间的电缆。


  6. 要移除一个适配器,请输入 5(从一个节点移除一个传输适配器)。

    按说明操作并输入系统请求的信息。您需要输入您尝试标识的电缆的一个端点的节点名称和适配器名称。


    *** Cluster Interconnect Menu **    Please select from one of the following options:
        ...
        5) Remove a transport adapter
        ...
        Option: 5
        ...
    >>> Remove a Cluster Transport Adapter <<<
        ...
        Is it okay to continue (yes/no) [yes]? <Return>
        ...
        To which node is the cable attached? nodename
        Name of the adapter on "node"? adaptername
        Is it okay to proceed with the update (yes/no) [yes]? <Return>
        ...
        Command completed successfully.    Hit ENTER to continue: <Return>
    

    注意:

    如果您要从节点移除一个物理适配器,请参见 Sun Cluster 3.0 Hardware Guide 中的硬件维护过程。


  7. 检验是否已移除电缆或适配器。


    # scconf -p | grep cable
    # scconf -p | grep adapter
    

    此命令的输出中不应出现已从给定节点移除的传输电缆或适配器。

5.1.3.1 示例-移除传输电缆或传输适配器

以下示例展示如何使用 scsetup 命令来移除一个传输电缆或传输适配器。


[Become superuser on a node in the cluster.]
[Execute the scsetup utility:]
# scsetup
[Enter option 2:]
*** Main Menu ***
    Please select from one of the following options:
    ...
      2) Cluster interconnect
    ...    Option: 2
[Enter option 4 to remove a cable:]
*** Cluster Interconnect Menu ***
    Please select from one of the following options:
    ...
      4) Remove a transport cable
    ...
    Option: 4
[Enter the requested information:]
>>> Remove a Cluster Transport Cable <<<
    ...

    ...
    To which node is the cable attached? phys-schhost-2
    Name of the adapter on "phys-schost-2"? qfe-0
    Is it okay to proceed with the update (yes/no) [yes]? <Return>	.
scconf -a -m endpoint=phys-schost-2:hme1,endpoint=hub0
    Command completed successfully.    Hit ENTER to continue: <Return>
[Enter option 5 to remove an adapter:]
