[font=Tahoma,][size=26px]oracle udev用法[font=Tahoma,][font=Arial, sans-serif]
最近在用vbox安装oracle 11g rac 需要用udev绑定asm盘，所以总结了一下udev用法。
1、修改配置文件 /etc/scsi_id.config ，添加配置项(不添加该项经测试也能成功)[font=Arial, sans-serif]options=-g

[font=Arial, sans-serif]2、如添加了三块SCSI磁盘 /dev/sdb,/dev/sdc,/dev/sdd[font=Arial, sans-serif]Oracle Linux 5 配置规则如下：[font=Arial, sans-serif]KERNEL=="sdb", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/sdb", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asmdisk1", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sdc", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/sdc", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asmdisk2", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sdd", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/sdd", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asmdisk3", OWNER="grid", GROUP="asmdba", MODE="0660"[font=Arial, sans-serif]Oracle Linux 6 配置规则如下:[font=Arial, sans-serif]KERNEL=="sdb", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/sdb", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asmdisk1", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sdc", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/sdc", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asmdisk2", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sdd", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/sdd", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asmdisk3", OWNER="grid", GROUP="asmdba", MODE="0660"[font=Arial, sans-serif]注：也可先对磁盘分区，再对分区进行配置，同时使用通配符，如下所示(Oracle Linux 6)[font=Arial, sans-serif]KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asmdisk1", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asmdisk2", OWNER="grid", GROUP="asmdba", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asmdisk3", OWNER="grid", GROUP="asmdba", MODE="0660"[font=Arial, sans-serif]3、更行块设备分区表信息[font=Arial, sans-serif]/sbin/partprobe /dev/sdb[font=Arial, sans-serif]/sbin/partprobe /dev/sdc[font=Arial, sans-serif]/sbin/partprobe /dev/sdd[font=Arial, sans-serif]
4、重启udev设备[font=Arial, sans-serif]/sbin/udevcontrol reload_rules (Oracle Linux 5)[font=Arial, sans-serif]/sbin/udevadm control --reload-rules (Oracle Linux 6)[font=Arial, sans-serif]/sbin/start_udev[font=Arial, sans-serif]5、测试udev设备[font=Arial, sans-serif]/sbin/udevtest /block/sdb (Oracle Linux 5)[font=Arial, sans-serif]/sbin/udevadm test /dev/sdb (Oracle Linux 6)
