一、识别硬盘的scsi_id(/sbin/scsi_id)
RHEL5
/sbin/scsi_id -g -u -s /block/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
RHEL6
/sbin/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
RHEL7
/usr/lib/udev/scsi_id -g -u -d /dev/sdb
SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_
二、使SCSI设备可信
编辑文件 “/etc/scsi_id.config”.
options=-g
三、创建UDEV Rules File(以分区为对象而不是硬盘)
编辑文件etc/udev/rules.d/99-oracle-asmdevices.rules” .
vi /etc/udev/rules.d/99-oracle-asmdevices.rules
RHEL5
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asm-disk2", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asm-disk3", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -s /block/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", NAME="asm-disk4", OWNER="grid", GROUP="asmadmin", MODE="0660"
RHEL6.
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", NAME="asm-disk1", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", NAME="asm-disk2", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172_", NAME="asm-disk3", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", NAME="asm-disk4", OWNER="grid", GROUP="asmadmin", MODE="0660"
RHEL7
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBd306dbe0-df3367e3_", SYMLINK+="asm-disk1", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB46dec7e0-192e8000_", SYMLINK+="asm-disk2", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VBce8c63bb-ac67a172", SYMLINK+="asm-disk3", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd?1", SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id -g -u -d /dev/$parent", RESULT=="SATA_VBOX_HARDDISK_VB7437a3b7-95b199cd_", SYMLINK+="asm-disk4", OWNER="grid", GROUP="asmadmin", MODE="0660"
四、加载更新后的块设备 (/sbin/partprobe)
/sbin/partprobe /dev/sdb1
/sbin/partprobe /dev/sdc1
/sbin/partprobe /dev/sdd1
/sbin/partprobe /dev/sde1
五、测试rule文件 (udevtest)
RHEL5
udevtest /block/sdb/sdb1
udevtest /block/sdc/sdc1
udevtest /block/sdd/sdd1
udevtest /block/sde/sde1
RHEL6 and RHEL7
udevadm test /block/sdb/sdb1
udevadm test /block/sdc/sdc1
udevadm test /block/sdd/sdd1
udevadm test /block/sde/sde1
六、重启UDEV Service
RHEL5
/sbin/udevcontrol reload_rules
RHEL6 and RHEL7
udevadm control --reload-rules
RHEL5 and RHEL6(RHEL7不需要)
/sbin/start_udev
七、查看所有者和权限
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:在OL 6上创建UDEV规则,以硬盘为单位而不是分区
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$name", RESULT=="36001405a6f3fb71b9c5470894e6a2f4d", NAME="asm-disk1", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$name", RESULT=="3600140537d716c0e80d445d9fb330d3f", NAME="asm-disk2", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -u -d /dev/$name", RESULT=="360014058f70453d23c7493dae489a42d", NAME="asm-disk3", OWNER="grid", GROUP="asmadmin", MODE="0660"
