Sun Cluster 系統管理指南 (適用於 Solaris 作業系統)

關閉與啟動叢集概觀

Sun Cluster scshutdown(1M) 指令以順序方式停止叢集服務，並徹底關閉整個叢集。您可以在移動叢集的位置時使用 scshutdown 指令。如果由於應用程式錯誤導致資料毀損，您也可以使用這個指令關閉叢集。

注意 –

請使用 scshutdown 指令，而不是 shutdown 或 halt 指令，以確保整個叢集正常關閉。Solaris shutdown 指令與 scswitch(1M) 指令配合使用來關閉個別節點。請參閱 如何關閉叢集 或 關閉與啟動單一叢集節點，以取得詳細資訊。

scshutdown 指令以下列方式停止叢集中所有節點：

  1. 使所有執行中的資源群組進入離線狀態。

  2. 卸載所有的叢集檔案系統。

  3. 關閉作用中的裝置服務。

  4. 執行 init 0，將所有節點引入 OpenBootTM PROM ok 提示符號處 (在以 SPARC6 為基礎的系統上) 或引入啟動子系統 (在以 x86 為基礎的系統上)。在System Administration Guide: Basic Administration中的「Boot Subsystems」中對啟動子系統進行了更詳細的說明。

注意 –

如有需要，您可在非叢集模式下啟動節點，如此該節點便不會以叢集成員身份參與。在安裝叢集軟體或執行某些管理程序時，非叢集模式非常有用。請參閱 如何以非叢集模式啟動叢集節點，以取得詳細資訊。

表 3–1 作業清單：關閉與啟動叢集

工作 

相關說明 

停止節點 

    － 使用 scshutdown(1M)

請參閱如何關閉叢集

以啟動所有節點的方式來啟動叢集。 

節點和叢集互連之間必須有運轉中的連線，才能夠成為叢集成員。 

請參閱如何啟動叢集

重新啟動叢集 

    － 使用 scshutdown

在 [目前的啟動參數] 螢幕上顯示 ok 或 Select (b)oot or (i)nterpreter 提示符號時，請使用 boot(1M) or the b 指令個別啟動每一個節點。

節點和叢集互連之間必須有運轉中的連線，才能夠成為叢集成員。 

請參閱如何重新啟動叢集

如何關閉叢集

注意 – 注意 –

請勿在叢集主控台上使用 send brk 來關閉叢集節點。叢集中並不支援這個指令。

  1. SPARC：如果您的叢集正在執行 Oracle Parallel Server 或 Real Application Clusters，請關閉所有資料庫實例。

    請參閱 Oracle Parallel Server or Oracle Real Application Clusters 產品說明文件，以取得關機程序的說明。

  2. 成為叢集中任何節點的超級使用者。

  3. 立即關閉叢集。

    從叢集中的單一節點，輸入下列指令。


    # scshutdown -g0 -y

  4. 在以 SPARC 為基礎的系統或在以 x86 為基礎的系統之啟動子系統上，請確認所有節點均顯示 ok 提示符號。

    在基於 SPARC 的系統或在基於 x86 的系統之啟動子系統上，除非所有叢集節點均已顯示 ok 提示符號，否則不要關閉任何節點的電源。

  5. 必要時，關閉節點的電源。

SPARC: 範例—關閉叢集

以下範例顯示在停止叢集正常作業並關閉所有節點使其顯示 ok 提示符號時的主控台輸出。-g 0 選項可將關機寬限期設成零，-y 提供自動的 yes 回應，以確認問題。關機訊息還會顯示在叢集中其他節點的主控台上。

下一步

請參閱 如何啟動叢集，以重新啟動已經關機的叢集。

如何啟動叢集

  1. 若要啟動節點已關閉、並在 [目前的啟動參數] 螢幕上顯示 ok 提示符號或 Select (b)oot or (i)nterpreter 提示的叢集，請 boot(1M) 每個節點。

    如果您在關機期間變更任何配置，請先以最近的配置啟動節點。除此情形外，節點的啟動順序並無影響。

    • SPARC：


      ok boot

    • x86：


                            <<< Current Boot Parameters >>>
Boot path: /pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/
sd@0,0:a
Boot args:

Type    b [file-name] [boot-flags] <ENTER>  to boot with options
or      i <ENTER>                           to enter boot interpreter
or      <ENTER>                             to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b

    當叢集元件啟動時，訊息會出現在啟動節點的主控台上。

    注意 –

    叢集節點和叢集互連之間必須有運轉中的連線，才能夠成為叢集成員。

  2. 確認節點啟動成功而且是在線上狀態。

    scstat(1M) 指令可報告節點的狀態。


     # scstat -n

    注意 –

    如果叢集節點的 /var 檔案系統已滿，Sun Cluster 可能無法在該節點上重新啟動。如果發生此問題，請參閱如何修復整個 /var 檔案系統。

如何重新啟動叢集

執行scshutdown(1M) 指令關閉叢集，然後在每個節點上使用 boot(1M) 指令啟動叢集。

  1. SPARC：如果叢集正在執行 Oracle Parallel Server or Oracle Real Application Clusters，請關閉所有資料庫實例。

    請參閱 Oracle Parallel Server or Oracle Real Application Clusters 產品說明文件，以取得關機程序的說明。

  2. 成為叢集中任何節點的超級使用者。

  3. 關閉叢集。

    從叢集中的單一節點，輸入下列指令。


    # scshutdown -g0 -y

    會關閉每一個節點。

    注意 –

    叢集節點和叢集互連之間必須有運轉中的連線，才能夠成為叢集成員。

  4. 啟動每一個節點。

    節點的啟動順序沒有任何影響，除非您在兩次關機之間進行配置變更。如果您在關機期間變更任何配置，請先以最近的配置啟動節點。

    • SPARC：


      ok boot

    • x86：


                            <<< Current Boot Parameters >>>

or      <ENTER>                             to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b

    當叢集元件啟動時，訊息會出現在啟動節點的主控台上。

  5. 確認節點啟動成功而且是在線上狀態。

    scstat 指令可報告節點的狀態。


     # scstat -n

    注意 –

    如果叢集節點的 /var 檔案系統已滿，Sun Cluster 可能無法在該節點上重新啟動。如果發生此問題，請參閱如何修復整個 /var 檔案系統。

SPARC: 範例—重新啟動叢集

以下範例顯示先停止叢集正常作業並關閉所有節點使其顯示 ok 提示符號、然後重新啟動叢集時的主控台輸出。-g 0 選項可將寬限期設成零，-y 提供自動的 yes 回應，以確認問題。關機訊息還會出現在叢集中其他節點的主控台上。
