[grid@node1 ~]$
2.5 检查SCAN
检查scan-ip地址的配置
[grid@node1 ~]$ srvctl config scan
SCAN name: scan-cluster.com, Network: /192.168.0.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /scan-cluster/192.168.0.24
SCAN VIP name: scan2, IP: /scan-cluster/192.168.0.25
SCAN VIP name: scan3, IP: /scan-cluster/192.168.0.26
[grid@node1 ~]$ 检查scan-ip地址的实际分布及状态

ASM listener: LISTENER
ASM is enabled.
[grid@node1 ~]$ 检查磁盘组
[grid@node1 ~]$ srvctl status diskgroup -g DATA
Disk Group DATA is running on node1,node2
[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
