以上操作将加载oracleasm.o驱动，并且mount上ASM文件系统，同时我们可以通过以下命令来手工的卸载和加载ASMLib# /etc/init.d/oracleasm disable Writing Oracle ASM library driver configuration [ OK ] Unmounting ASMlib driver filesystem [ OK ] Unloading module "oracleasm" [ OK ] # /etc/init.d/oracleasm enable Writing Oracle ASM library driver configuration [ OK ] Loading module "oracleasm" [ OK ] Mounting ASMlib driver filesystem [ OK ] Scanning system for ASM disks [ OK ]

如果当前操作系统的内核和编译ASMLib的内核不同，那么上面的操作将会出错，请检查/var/log/messages文件，确认需要更新的系统内核版本。

添加init文件使系统启动时自动加载ASMLib$ su – # cd /etc/rc3.d # ln -s ../init.d/oracleasm S99oracleasm # ln -s ../init.d/oracleasm K01oracleasm

注意：如果系统启动是自动进入图形界面，也就是系统的init level是5，那么上面生成链接的命令应该在/etc/rc5.d目录中操作。

重新启动系统，确认ASMLib已经可以自动加载#lsmod | grep oracleasm oracleasm 14224 1 #dmesg | grep oracleasm ASM: oracleasmfs mounted with options:
