[grid@node1 ~]$  

查看ASM磁盘

[root@node1 bin]# oracleasm listdisks

VOL1

VOL2

[root@node1 bin]#

查看物理磁盘与asm 磁盘对应关系

[root@node1 bin]# oracleasm querydisk -v -p VOL1

Disk "VOL1" is a valid ASM disk

/dev/sdb1: LABEL="VOL1" TYPE="oracleasm"

[root@node1 bin]#

2.8检查集群节点间的时钟同步

检查节点node1的时间同步

[grid@node1 ~]$ cluvfy comp clocksync -verbose

.......

Verification of Clock Synchronization across the cluster nodes was successful.

[grid@node1 ~]$

检查节点node2的时间同步

[grid@node2 ~]$ cluvfy comp clocksync -verbose

..............

CTSS is in Active state. Proceeding with check of clock time offsets on all nodes...

Reference Time Offset Limit: 1000.0 msecs

Check: Reference Time Offset

  Node Name     Time Offset               Status

  ------------  ------------------------  ------------------------

  node2         -89900.0                  failed

Result: PRVF-9661 : Time offset is NOT within the specified limits on the following nodes:

"[node2]" 

PRVF-9652 : Cluster Time Synchronization Services check failed

Verification of Clock Synchronization across the cluster nodes was unsuccessful on all the specified nodes.

[grid@node2 ~]$

　　注：节点2的服务器时间出现问题

　　至此，对Grid的巡检基本上就算完成了
