linux下asm创建
1,关闭selinux
[root@rac1 opt]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
#SELINUX=enforcing
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
保证selinux的值为：disable，并重启主机
2，下载asm软件
[root@rac1 opt]# uname -a
Linux rac1 2.6.18-274.el5 #1 SMP Fri Jul 8 17:36:59 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

3,启动asm
[root@rac1 opt]# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: Default group to own the driver interface []:
Start Oracle ASM library driver on boot (y/n) [y]:
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 opt]# /etc/init.d/oracleasm enable
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
[root@rac1 opt]# df -ha | grep oracleasm
oracleasmfs 0 0 0 - /dev/oracleasm
附启用或禁用oracleasm自动启动方法:
# /etc/init.d/oracleasm disable
# /etc/init.d/oracleasm enable
4，创建asm磁盘卷
ASM磁盘名可以为大写字母,数字和下划线,且以字母开始:
# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb1
Marking disk "VOL1" as an ASM disk: [ OK ]
如果提示Failed, 可以跟踪日志:
# tail -f /var/log/oracleasm
附删除磁盘语句:
# /etc/init.d/oracleasm deletedisk VOL1
检查配置情况:
# /etc/init.d/oracleasm querydisk VOL1
# /etc/init.d/oracleasm querydisk /dev/sdb1
# /etc/init.d/oracleasm listdisks
# ls -l /dev/oracleasm/disks/*
# /etc/init.d/oracleasm status
如果oracle要安装在asm磁盘上，需要执行如下步骤！
[root@rac1 CentOS]# /opt/app/oracle/product/10.2.0/bin/localconfig add
/etc/oracle does not exist. Creating it now.
