Oracle使用raw via lvm

早上为另外一个公司的一个生产库处理raw使用的问题，现场人员说要把新的lvm的空间给Oracle使用，已经化好lv了，也绑定了映射，但是一直看不到raw；检查了下相关绑定规则参数，而且已经有在使用的规则绑定，他只是copy了新的规则并稍作修改，但是就是不生效。以下是测试过程。[root@o564gtser1 ~]# fdisk -l Disk /dev/sddDisk /dev/sdd: 524 MB, 524288000 bytes

使用手工测试了下发现是可以的：
[root@o564gtser1 ~]# /bin/raw /dev/raw/raw3 /dev/mapper/oravg-oralv1
/dev/raw/raw3: bound to major 253, minor 0
[root@o564gtser1 ~]# /bin/raw /dev/raw/raw4 /dev/mapper/oravg-oralv2
/dev/raw/raw4: bound to major 253, minor 1
[root@o564gtser1 ~]# raw -qa
/dev/raw/raw1: bound to major 8, minor 16
/dev/raw/raw2: bound to major 8, minor 32
/dev/raw/raw3: bound to major 253, minor 0
/dev/raw/raw4: bound to major 253, minor 1
[root@o564gtser1 ~]# ll /dev/raw/*
crw-r----- 1 oracle oinstall 162, 1 04-18 13:03 /dev/raw/raw1
crw-r----- 1 oracle oinstall 162, 2 04-18 13:03 /dev/raw/raw2
crw-r----- 1 oracle oinstall 162, 3 04-18 13:09 /dev/raw/raw3
crw-r----- 1 oracle oinstall 162, 4 04-18 13:10 /dev/raw/raw4
只好将上述两行命令写入/etc/rc.d/rc.local ：
#add by gtlions test for lvm used in oracle
/bin/raw /dev/raw/raw3 /dev/mapper/oravg-oralv1
/bin/raw /dev/raw/raw4 /dev/mapper/oravg-oralv2
chown oracle:oinstall /dev/raw/raw3
chown oracle:oinstall /dev/raw/raw4
chmod 640 /dev/raw/raw3
chmod 640 /dev/raw/raw4
并删除/etc/udev/rules.d/60-raw.rules内的原来设置的内容即可。
这样就可以在Oracle中使用了：
