随心所欲的指定RAC中的节点号

标题:随心所欲的指定RAC中的节点号

作者:Lunar©版权所有[文章允许转载,但必须以链接方式注明源地址,否则追究法律责任.]

考虑到节点逐出的规则,其中有一个跟节点号有关系,即缺省节点号小的被保留,大的被逐出(还有很多其他条件,比如分组等,这里不细说)
那天群里有人说了希望修改节点号的需求,今天忽然想起来试试看,结论如下:
1,可以使用ocrpatch任意指定任一个节点的节点号
2,不指定的情况,安装的节点为节点1,其余的顺次往下排

备份下当前OCR和VOT的信息:

[root@RAC1 ~]# olsnodes -s -t -n
rac1    1       Active  Unpinned
rac2    2       Active  Unpinned
[root@RAC1 ~]# 

[root@RAC1 ~]# ocrconfig -showbackup

rac1     2013/11/01 19:37:35     /u01/11.2.0/grid/cdata/racdb/backup00.ocr

rac1     2013/11/01 15:37:33     /u01/11.2.0/grid/cdata/racdb/backup01.ocr

rac1     2013/11/01 15:37:33     /u01/11.2.0/grid/cdata/racdb/day.ocr

rac1     2013/11/01 15:37:33     /u01/11.2.0/grid/cdata/racdb/week.ocr
PROT-25: Manual backups for the Oracle Cluster Registry are not available
[root@RAC1 ~]# 


这里,我们可以看见,节点1(rac1)的节点号是1,节点2(rac2)的节点号是2。。。
我打算把它修改为节点1(rac1)的节点号是2,节点2(rac2)的节点号是1

再开2个会话,分别用于停止节点1和节点2的crs:

初始化votdisk:


[root@RAC1 tmp]# crsctl replace votedisk +DATA
CRS-4256: Updating the profile

voting disk重新配置的信息如下:

再次查询,以前的节点1,的节点号已经被修改为node 2了:


[root@RAC1 tmp]# olsnodes -s -t -n
rac2    1       Active  Unpinned
rac1    2       Active  Unpinned
[root@RAC1 tmp]# 


这里如果你不需要修改其他的节点,那么其他节点就从最小的没有被使用的数字中顺序读取,如果假设有8个节点,那么你可以指定其中的所有节点号,按照你希望的顺序,分别制定,方法同上面。
