为测试一个迁移方案，装了一套10g rac环境，可能是很久没有装过10g的RAC了，整个过程情况不断。
1.在把集群软件和数据库软件都装好之后，用crs_stat检测状态的时候，发现vip的状态不对，ping vipIP不通
[root@rac10g01 ~]# cd $CRS_HOME
[root@rac10g01 crs_1]# crs_stat -t
Name Type Target State Host
------------------------------------------------------------
ora....g01.gsd application ONLINE ONLINE rac10g01
ora....g01.ons application ONLINE ONLINE rac10g01
ora....g01.vip application ONLINE OFFLINE
ora....g02.gsd application ONLINE ONLINE rac10g02
ora....g02.ons application ONLINE ONLINE rac10g02
ora....g02.vip application ONLINE OFFLINE
2.随后用命令，crs_start去启动vip，也报错：
[root@rac10g01 crs_1]# crs_start ora.rac10g01.vip
Attempting to start `ora.rac10g01.vip` on member `rac10g01`
Start of `ora.rac10g01.vip` on member `rac10g01` failed.
Attempting to start `ora.rac10g01.vip` on member `rac10g02`

CRS-1006: No more members to consider
CRS-0215: Could not start resource 'ora.rac10g01.vip'.
3.查看了下vip的日志：$CRS_HOME/log/$hostname/racg/ora.rac10g01.vip.log，里面报错：

4.在log里面看到vip也显示的ping不通。debug一下启动的过程：
[root@rac10g01 bin]# crsctl debug log res "ora.rac10g01.vip:5"
Set Resource Debug Module: ora.rac10g01.vip Level: 5
[root@rac10g01 bin]# crs_start ora.rac10g01.vip

CRS-1006: No more members to consider
CRS-0215: Could not start resource 'ora.rac10g01.vip'.
在log里面显示:

5.看到ping网关的时候都ping不通，检查一下racgvip里面的DEFAULTGW设置
发现DEFAULTGW=
没有做设置。手工设置一下DEFAULTGW=192.168.146.1，在第二个节点也修改一下。两个节点都修改好之后，重启vip的资源，success了。
