Configure ASM using udev scsi Rules on Oracle Linux 5 and 6

UDEV ASMDisk Configuration
Because Oracle does not support the RHEL6 series ASMLib, we can change it to Udev to configure ASMDisk as follows:
 
Use udev to configure the block device information stored in ASM.
 
1. confirm that the udev package is installed.
[Root @ rac01 ~] # Rpm-qa | grep udev
Udev-147-2.40.el6.x86_64
 
2. Obtain the WWID system information of the hard disk.
(1) Use the following command in Oracle Linux 5
[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) Use the following command in Oracle Linux 6
[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. The hard drive of/dev/sdb 4G is divided into two primary partitions, two GB for each partition, to achieve OCR information redundancy.
[Root @ rac01 ~] # Fdisk/dev/sdb
 
4. Divide the hard drive of/dev/sdc 8 GB into four logic units, each of which is 2 GB to store data files.
[Root @ rac01 ~] # Fdisk/dev/sdc
 
5. Configure the udev configuration file
Important: each configuration file contains a rule with a space between (comma) and the next keyword.
[Root @ rac01 ~] # Cd/etc/udev/rules. d/
[Root @ rac01 rules. d] # vi 99-oracle-asmdisk.rules
(1) Oracle Linux 5 uses the following parameters:
KERNEL = "sd? [1-2] ", 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 ″

(2) Oracle Linux 6 uses the following parameters:
KERNEL = "sd? [1-2] ", 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? [5-8] ", 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 ″
6. confirm that the configuration is normal and the block device permission is correct.
