九、 创建ASM磁盘
删除asm磁盘
oracleasm deletedisk DATA_0003 清理asm磁盘
dd if=/dev/zero of=/dev/sdc1 bs=1024 count=100 dd if=/dev/zero of=/dev/sdd1 bs=1024 count=100 dd if=/dev/zero of=/dev/sdf1 bs=1024 count=100
创建ASM磁盘
/etc/init.d/oracleasm createdisk NCRS_0001 /dev/sdc1 /etc/init.d/oracleasm createdisk NCRS_0002 /dev/sdd1 /etc/init.d/oracleasm createdisk NCRS_0003 /dev/sdf1
/etc/init.d/oracleasm createdisk DATA_0001 /dev/sdb1 /etc/init.d/oracleasm createdisk DATA_0002 /dev/sde1 /etc/init.d/oracleasm createdisk DATA_0003 /dev/sdg1 /etc/init.d/oracleasm createdisk DATA_0004 /dev/sdh1
查看以创建的ASM磁盘
[root@localhost ~]# /etc/init.d/oracleasm listdisks VOL1 VOL2
以下操作在另一个节点上进行 oracleasm scandisks
使用UDEV来管理： for i in b c d e f g h do echo \BUS==\\\PROGRAM==\\\--whitelisted --replace-whitespace --device=/dev/\\$name\\\RESULT==\\\--whitelisted --replace-whitespace --device=/dev/sd$i`\\\NAME=\\\OWNER=\\\GROUP=\\\done ;
将结果插入/etc/udev/rules.d/99-oracle-asmdevices.rules
十、 登录VNC安装grid infrastructure软件
