11gr2 rac改IP系列之四：修改私網IP為其它IP

--------------------------
修改私有ip為其它網段IP。
-----------------修改前：
192.168.58.1   bys1-priv.bys.com bys1-priv
192.168.58.2   bys2-priv.bys.com bys2-priv
-----------------修改後：
192.168.59.1   bys1-priv.bys.com bys1-priv
192.168.59.2   bys2-priv.bys.com bys2-priv
參考MOS文件：How to Modify Private Network Information in Oracle Clusterware (文件 ID 283684.1)
從11.2 Grid Infrastructure開始，私有網路配置儲存在OCR和gpnp配置檔案中。 如果專用網路不可用或其定義不正確，CRSD程式將不會啟動，並且後續不能對OCR進行更改。 注意，不支援手動修改gpnp配置檔案。
--------目錄
1.備份gpnp配置檔案
2.檢視當前叢集是執行狀態及OS層面網路卡資訊
3.檢視並修改私網配置資訊--單個節點進行
4.關閉CRS--兩個節點均進行
5.OS層面修改IP並修改/etc/hosts中記錄（兩個節點均修改）並測通
6.重新啟動叢集
7.刪除原有私網資訊並驗證
8.檢查叢集狀態

具體步驟：--僅顯示節點1，節點2同樣步驟。

1.備份gpnp配置檔案

$ cd $GRID_HOME/gpnp/<hostname>/profiles/peer/
---
[grid@bys1 ~]$ cd /u01/11.2.0/grid/gpnp/bys1/profiles/peer/
[grid@bys1 peer]$ ls
pending.xml  profile.old  profile_orig.xml  profile.xml
[grid@bys1 peer]$ cp profile.xml profile.xmlbak

[grid@bys2 ~]$ cd  /u01/11.2.0/grid/gpnp/bys2/profiles/peer/
[grid@bys2 peer]$ cp profile.xml profile.xmlbak

2.檢視當前叢集是執行狀態及OS層面網路卡資訊

[grid@bys2 peer]$ crsctl stat res -t

3.檢視並修改私網配置資訊--單個節點進行

4.關閉CRS--兩個節點均進行
[root@bys1 ~]#  crsctl stop crs
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'bys1'
………………
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'bys1' has completed
CRS-4133: Oracle High Availability Services has been stopped.
[root@bys1 ~]# crsctl disable crs
CRS-4621: Oracle High Availability Services autostart is disabled.


###############
5.OS層面修改IP並修改/etc/hosts中記錄（兩個節點均修改）並測通

-----------------修改前：

192.168.58.2   bys2-priv.bys.com bys2-priv
-----------------修改後：
192.168.59.1   bys1-priv.bys.com bys1-priv
192.168.59.2   bys2-priv.bys.com bys2-priv

7.刪除原有私網資訊並驗證

[grid@bys1 ~]$ oifcfg getif
