在Oracle Linux 5 和6上使用UDEV SCSI Rules配置ASM
UDEV ASMDisk 配置 因为Oracle 不出支持 RHEL6 系列的 ASMLib,所以我们可以改为 Udev 的方式配置ASMDisk,
UDEV ASMDisk 配置
因为Oracle 不出支持 RHEL6 系列的 ASMLib,,所以我们可以改为 Udev 的方式配置ASMDisk,详细如下:
优先使用udev 的方式配置ASM存储的块设备信息。
1.确认udev包已安装
[root@rac01 ~]# rpm -qa | grep udev
udev-147-2.40.el6.x86_64
2.获得硬盘WWID系统信息
(1) Oracle Linux 5 用如下命令
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdc
SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sdd
SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_
[root@rac01 ~]# /sbin/scsi_id -g -u -s /block/sde
SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_
(2) Oracle Linux 6 用如下命令
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdc
SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sdd
SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_
[root@rac01 ~]# /sbin/scsi_id -g -u -d /dev/sde
SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_
3.对/dev/sdb 4G的硬盘分2个主分区,每个区2G,以实现OCR信息的冗余
[root@rac01 ~]# fdisk /dev/sdb
4.对/dev/sdc 8G的硬盘分4个逻辑个,每个区2G,以存储数据文件
[root@rac01 ~]# fdisk /dev/sdc
5. 配置udev配置文件
重要:每个配置文件一行为一条规则,并且,(逗号)与下一个关键词之间有空格。
[root@rac01 ~]# cd /etc/udev/rules.d/
[root@rac01 rules.d]# vi 99-oracle-asmdisk.rules

6. 确认配置正常,块设备的权限正确
# cd /dev
# ls -al asm-disk*
