oifcfg setif -global ens224/10.132.125.129:cluster_interconnect 保存了错误的gpnp profile.xml 中 心跳网络 ens224/10.132.125.128 正确的，被保存错了ens224/10.132.125.129，和 ocr 中私有网络无法匹配，导致 crs 服务无法启动。后来客户还对ocr还做了还原操作。（最近8小时的备份，修改心跳网络之前的ocr备份）
解决方案
[root@host01 ~]# cd /u01/app/11.2.0/grid/gpnp/host01/profiles/peer/
[root@host01 peer]# cp profile.xml profile.bak
– remove the oracle signature from the file –
[root@host01 peer]# gpnptool unsign -p=profile.bak
Warning: some command line parameters were defaulted. Resulting command line:
/u01/app/11.2.0/grid/bin/gpnptool.bin unsign -p=profile.bak -o-
– change the DiscoveryString itself –
unnamed1!
Resulting profile written to “profile.bak”.
Success.
-- 修改 net2 私有网络 和 profllesequence 序列号（改大）
vi profile.bak
/ * gpnptool edit xxx -p=profile.bak -o=profile.bak -ovr
-prf_sq=<序列号>
* /
– sign the profile xml file with the wallet (Notice: the path is only the directory to the wallet, NOT the wallet file itself) –
[root@host01 peer]# gpnptool sign -p=profile.bak -w=file:/u01/app/11.2.0/grid/gpnp/host01/wallets/peer/ -o=profile.new
Resulting profile written to “profile.new”.
Success.
– move the original profile.xml out of the way
[root@host01 peer]# mv profile.new profile.xml
– check that discovery string has been modified
[root@host01 peer]# cat profile.xml
修改后又遇到启动无法扫描的asm盘的问题
crsctl start crs -excl -nocrs 独占模式
sqlplus / as sysasm
create pfile='/home/oracle/xxx.pfile' from spfile = 'xxx' 保存一份pfile文件
alter system set asm_diskstring='/dev/mapper/*'; 会更新到gpnp里面
