[root@node1 bin]# oracleasm listdisks
VOL1
VOL2
[root@node1 bin]#
查看物理磁盤與asm 磁盤對應關系
[root@node1 bin]# oracleasm querydisk -v -p VOL1
Disk "VOL1" is a valid ASM disk

2.8檢查集群節點間的時鍾同步
檢查節點node1的時間同步 [grid@node1 ~]$ cluvfy comp clocksync -verbose ....... Verification of Clock Synchronization across the cluster nodes was successful. [grid@node1 ~]$
檢查節點node2的時間同步 [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：節點2的服務器時間出現問題
至此，對Grid的巡檢基本上就算完成了
