Sun Cluster 系統管理指南（適用於 Solaris 作業系統）

Procedure如何驗證基本叢集配置

sccheck(1M) 指令執行一系列檢查，以驗證叢集所需的基本配置是否運作正常。如果所有檢查均順利完成，sccheck 將返回到 shell 提示符號。如果有某個檢查失敗，則 sccheck 將在指定的或預設的輸出目錄中產生報告。如果您對一個以上的節點執行 sccheck，sccheck 將會產生一個針對各個節點的報告和一個針對多個節點檢查的報告。

sccheck 指令分兩個步驟執行﹕資料收集與分析。依據系統配置的不同，資料收集可能會很費時。您可以使用 -v1 旗標在冗長模式中呼叫 sccheck 來列印進度訊息，或者您可以使用 -v2 旗標在特別冗長的模式中執行 sccheck，在此模式下，可以列印更詳細的進度訊息，尤其是在資料收集期間。

備註 –

請於執行完某個可能導致裝置、容體管理元件或 Sun Cluster 配置變更的管理程序之後，執行 sccheck。

步驟

  1. 成為叢集中任何節點的超級使用者。

  2. 確認叢集配置。


     # sccheck
範例 1–7 檢查叢集配置時所有檢查全部通過

以下範例顯示針對節點 phys-schost-1 和 phys-schost-2 在詳細模式中執行的 sccheck，且所有檢查全部通過。


# sccheck -v1 -h phys-schost-1,phys-schost-2

sccheck: Requesting explorer data and node report from phys-schost-1.
sccheck: Requesting explorer data and node report from phys-schost-2.
sccheck: phys-schost-1: Explorer finished.
sccheck: phys-schost-1: Starting single-node checks.
sccheck: phys-schost-1: Single-node checks finished.
sccheck: phys-schost-2: Explorer finished.
sccheck: phys-schost-2: Starting single-node checks.
sccheck: phys-schost-2: Single-node checks finished.
sccheck: Starting multi-node checks.
sccheck: Multi-node checks finished
#
範例 1–8 檢查叢集配置時有一個檢查未通過

以下範例顯示缺少掛載點 /global/phys-schost-1 的叢集 suncluster 中的節點 phys-schost-2。報告建立在輸出目錄 /var/cluster/sccheck/myReports/ 中。


# sccheck -v1 -h phys-schost-1,phys-schost-2 -o /var/cluster/sccheck/myReports
sccheck: Requesting explorer data and node report from phys-schost-1.
sccheck: Requesting explorer data and node report from phys-schost-2.
sccheck: phys-schost-1: Explorer finished.
sccheck: phys-schost-1: Starting single-node checks.
sccheck: phys-schost-1: Single-node checks finished.
sccheck: phys-schost-2: Explorer finished.
sccheck: phys-schost-2: Starting single-node checks.
sccheck: phys-schost-2: Single-node checks finished.
sccheck: Starting multi-node checks.
sccheck: Multi-node checks finished.
sccheck: One or more checks failed.
sccheck: The greatest severity of all check failures was 3 (HIGH).
sccheck: Reports are in /var/cluster/sccheck/myReports.
# 
# cat /var/cluster/sccheck/myReports/sccheck-results.suncluster.txt

------------------------------------
CHECK ID : 3065
SEVERITY : HIGH
FAILURE  : Global filesystem /etc/vfstab entries are not consistent across 
all Sun Cluster 3.x nodes.
ANALYSIS : The global filesystem /etc/vfstab entries are not consistent across 
all nodes in this cluster.
Analysis indicates:
FileSystem '/global/phys-schost-1' is on 'phys-schost-1' but missing from 'phys-schost-2'.
RECOMMEND: Ensure each node has the correct /etc/vfstab entry for the 
filesystem(s) in question.
