Sun Cluster 系统管理指南（适用于 Solaris OS）

Procedure如何验证基本群集配置

sccheck(1M) 命令运行一组检查来验证群集正常运行所需的基本配置。如果所有检查均未失败，sccheck 将返回到 shell 提示符。如果某项检查失败，sccheck 将在指定输出目录或缺省输出目录中生成报告。如果对多个节点运行 sccheck，sccheck 将为每个节点和多个节点的检查分别生成一个报告。

sccheck 命令按以下两个步骤运行：数据收集和数据分析。数据收集可能会耗费较长的时间，具体时间取决于系统配置。您可以通过在详细模式下使用 -v1 标志调用 sccheck 来打印进度信息，还可以通过在高度详细模式下使用 -v2 标志运行 sccheck 来打印更为详细的进度信息（尤其是在收集数据的过程中）。

注 –

在执行可能导致设备、卷管理组件或 Sun Cluster 的配置发生更改的管理过程之后，都应运行 sccheck。

步骤

  1. 成为群集中任一节点上的超级用户。

  2. 检验群集配置。


     # sccheck
示例 1–7 检查群集配置并且所有检查均通过

以下示例显示了针对节点 phys-schost-1 和 phys-schost-2 在详细模式下运行的 sccheck，其中节点通过了所有检查。


# 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
#
示例 1–8 检查群集配置并且某项检查未通过

以下示例显示了群集 suncluster 中缺少安装点 /global/phys-schost-1 的节点 phys-schost-2。报告是在输出目录 /var/cluster/sccheck/myReports/ 中创建的。


# 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.
