Configuring ASM with Udev SCSI on SuSE Linux Enterprise SP1

1. Edit the/etc/scsi_id.config file, if the file does not exist, create the file, and add the following line:Options=–whitelisted–replace-whitespace

2. Get the disk UUID that needs to be bound to ASM disk, for example we want to use/DEV/SDC and/DEV/SDD as ASM disks, then:

#/LIB/UDEV/SCSI_ID–WHITELISTED–REPLACE-WHITESPACE–DEVICE=/DEV/SDC

1ata_vbox_harddisk_vb36a9e548-1838194a

#/LIB/UDEV/SCSI_ID–WHITELISTED–REPLACE-WHITESPACE–DEVICE=/DEV/SDD

1ata_vbox_harddisk_vb9808fc7f-cdf35030

The path to scsi_id on SUSE Linux Enterprise SP1 is not the same as Rhel.

3. Write Udev rules file, program write scsi_id command, result in the above command to write the UUID returned.

Vi/etc/udev/rules.d/99-oracle-asmdevices.rules
kernel== "sd*", subsystem== "block", program== "/lib/udev/scsi_id–whitelisted–replace-whitespace–device=/dev/$name" , result== "1ata_vbox_harddisk_vb36a9e548-
1838194a ", name=" Asm-disk1″, owner= "grid", group= "Asmadmin", mode= "0660″
kernel== "sd*", subsystem== "block", program== "/lib/udev/scsi_id–whitelisted–replace-whitespace–device=/dev/$name" , result== "1ata_vbox_harddisk_vb9808fc7f-
Cdf35030″, Name= "Asm-disk2″, owner=" grid ", group=" Asmadmin ", mode=" 0660″

4. Test with UDEVADM, note that the Udevadm command does not accept a mount device name such as/DEV/SDC, and must be the original device name using/SYS/BLOCK/SDC.

Udevadm TEST/SYS/BLOCK/SDC in the display, there is an output similar to the following, indicating that the test is correct and that the/DEV/SDC device will be bound to/dev/asm-disk1 after Udev starts:

Udevadm_test:udev_log=6
Udevadm_test:devpath=/devices/pci0000:00/0000:00:0d.0/host4/target4:0:0/4:0:0:0/block/sdc
Udevadm_test:major=8 udevadm_test:minor=32
Udevadm_test:devname=/dev/asm-disk1
Udevadm_test:devtype=disk
Udevadm_test:action=add
Udevadm_test:subsystem=block

5. Start Udev

#/etc/init.d/boot.udev Restart–udev boot mode is different from Rhel

6. Check if the device is properly bound

# ls-l/dev/asm*
