【vbox】Redhat 4、5、6设置裸设备

RedHat 4 RAW配置


1修改裸设备服务的配置文件: /etc/sysconfig/rawdevices. 添加下面2行。


 格式：裸设备名 块设备名
/dev/raw/raw1 /dev/sdb1
/dev/raw/raw2 /dev/sdb2


2 设置Oracle 用户对裸设备的访问权限。
编辑UDEV的权限文件：/etc/udev/permissions.d/50-udev.permissions
找到raw device部分，修改成如下格式：
# raw devices
raw*:oracle:dba:0660
raw/*:oracle:dba:0660




3 确认裸设备服务自启动，2个节点都要执行
[root@raw1 /]# chkconfig --list rawdevices
rawdevices      0:off   1:off   2:off   3:on    4:on    5:on    6:off


4. 启动raw devices 服务，确认裸设备创建成功，权限正确：
[root@raw1 /]# service rawdevices restart
Assigning devices:
/dev/raw/raw1  -->   /dev/sdb1
/dev/raw/raw1:  bound to major 8, minor 17
/dev/raw/raw1  -->   /dev/sdb2
/dev/raw/raw1:  bound to major 8, minor 18


done


[oracle@raw2 ~]$ cd /dev/raw
[oracle@raw2 raw]$ ls -lrt
total 0
crw-rw----  1 oracle dba 162, 1 Feb 28 03:08 raw1
crw-rw----  1 oracle dba 162, 2 Feb 28 03:08 raw2


 


RedHat 5 RAW配置


1修改/etc/udev/rules.d/60-raw.rules 文件


ACTION=="add", KERNEL=="/dev/sdb1", RUN+="/bin/raw /dev/raw/raw1 %N"

2 重启服务：


[root@rac1 ~]# start_udev
Starting udev:         [  OK  ]


3 查看raw设备：
[root@rac1 ~]# ls -lrt /dev/raw


 


RedHat 5 UDEV SCSI Rules配置
1 获取需要绑定为ASM Disk的磁盘uuid
# /sbin/scsi_id -g -u -s /block/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_


2 新建/etc/udev/rules.d/99-oracle-asmdevices.rules,增加以下内容
KERNEL=="sd*1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"


3 重启服务：
[root@rac1 ~]# start_udev
Starting udev:         [  OK  ]


 


RedHat 6 UDEV SCSI Rules
1 编辑/etc/scsi_id.config文件，如果该文件不存在，则创建该文件，添加如下行：
options=--whitelisted --replace-whitespace


备注：在我的测试中，此步骤可以省略


2 获取需要绑定为ASM Disk的磁盘uuid，比如我们要使用/dev/sdc作为ASM磁盘，那么：
# scsi_id --whitelisted --replace-whitespace --device=/dev/sdc
1ATA_VBOX_HARDDISK_VB36a9e548-1838194a
或
# /sbin/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_


3 新建/etc/udev/rules.d/99-oracle-asmdevices.rules,增加以下内容
KERNEL=="sd*1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"
或
