11.2.0.3 rac增加节点执行root.sh报 ORA-15018,ORA-15072,ORA-15080

在rac增加节点时,在新节点执行root.sh报错:

这个是oracleasm 磁盘 新节点和老节点的 的主版本不一样导致的

郑全

具体修改新的节点的 /etc/sysconfig/oracleasm 文件ORACLEASM_SCANORDER="dm"
修改后,再重起新节点,磁盘的主版本就一样了.

看存在节点的磁盘主版本:
ls -ltr /dev/oracleasm/disks

两者明显不一样,这个需要修改 asm扫描的顺序:
具体修改新节点的 /etc/sysconfig/oracleasm 文件:
ORACLEASM_SCANORDER="mpath dm"
修改后,再重起新节点,磁盘的主版本就一样了.
