Sun Cluster 系统管理指南（适用于 Solaris OS）

Procedure如何检查全局安装点

sccheck(1M) 命令可检查 /etc/vfstab 文件中是否有有关群集文件系统及其全局安装点的配置错误。

注 –

在进行了影响到设备或卷管理组件的群集配置更改后，请运行 sccheck。

步骤

  1. 成为群集中任一节点上的超级用户。


    % su

  2. 检验群集配置。


     # sccheck
示例 1–9 检查全局安装点

以下示例显示了群集 suncluster 中缺少安装点 /global/schost-1 的节点 phys-schost-2。 报告将发送至输出目录 /var/cluster/sccheck/myReports/ 


# 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.

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.

FAILURE  : An unsupported server is being used as a Sun Cluster 3.x node.
ANALYSIS : This server may not been qualified to be used as a Sun Cluster 3.x node.  
Only servers that have been qualified with Sun Cluster 3.x are supported as 
Sun Cluster 3.x nodes.
RECOMMEND: Because the list of supported servers is always being updated, check with 
your Sun Microsystems representative to get the latest information on what servers 
are currently supported and only use a server that is supported with Sun Cluster 3.x.
