1. 使用vi /etc/udev/rules.d/99-oracle-asmdevices.rules命令,创建udev规则文件:
##OL5
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asm-disk2", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asm-disk3", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", NAME="asm-disk4", OWNER="oracle", GROUP="dba", MODE="0660"
##OL6
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asm-disk2", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asm-disk3", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", NAME="asm-disk4", OWNER="oracle", GROUP="dba", MODE="0660"
##OL7
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", SYMLINK+="asm-disk1", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", SYMLINK+="asm-disk2", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172", SYMLINK+="asm-disk3", OWNER="oracle", GROUP="dba", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", SYMLINK+="asm-disk4", OWNER="oracle", GROUP="dba", MODE="0660"
某些参考资料有如下:
创建配置文件
[root@strong ~]# cat /etc/scsi_id.config
options=-g --配置SCSI设备为可信任的
2.更新块设备的分区(/sbin/partprobe)
/sbin/partprobe /dev/sdb1
/sbin/partprobe /dev/sdc1
/sbin/partprobe /dev/sdd1
/sbin/partprobe /dev/sde1
3.测试规则
##OL5
udevtest /block/sdb/sdb1
udevtest /block/sdc/sdc1
udevtest /block/sdd/sdd1
udevtest /block/sde/sde1
##OL6 and OL7
udevadm test /block/sdb/sdb1
udevadm test /block/sdc/sdc1
udevadm test /block/sdd/sdd1
udevadm test /block/sde/sde1
4.重新载入规则文件及启动udev服务(重启UDEV服务):
##OL5
/sbin/udevcontrol reload_rules
##OL6 and OL7
udevadm control --reload-rules
##OL5 and OL6,Not needed for OL7
/sbin/start_udev
5.检查磁盘的所属关系和权限:
cd /dev
ls -al asm-disk*
brw-rw---- 1 oracle dba 8, 17 Apr 8 22:47 asm-disk1
brw-rw---- 1 oracle dba 8, 33 Apr 8 22:47 asm-disk2
brw-rw---- 1 oracle dba 8, 49 Apr 8 22:47 asm-disk3
brw-rw---- 1 oracle dba 8, 65 Apr 8 22:47 asm-disk4
附上一个在OL6上快速生成udev规则文件的脚本:
for i in b c d e f g;
do
echo "KERNEL==\"sd*\", BUS==\"scsi\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/sd$i`\", NAME=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"" >> /etc/udev/rules.d/99-oracle-asmdevices.rules
done
OL7上快速生成udev规则文件的脚本:for i in c1 c2 c3;doecho "KERNEL==\"sd$i\", SUBSYSTEM=\"block\", PROGRAM==\"/usr/lib/udev/scsi_id -g -u -d /dev/\$parent\", RESULT==\"`/usr/lib/udev/scsi_id --device=/dev/sd$i`\", SYMLINK+=\"asm-disk$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\""done
