Udev Rule For ASM Disks

In Case of RAC configure on VM - After Adding ASM disk on Node 1 adding asm disk in UDEV rules for persistent.

------------------
IN RHEL/OEL-5/6/7
------------------Set Asm disk using UDEV
/sbin/scsi_id -g -u -d /dev/sdb
/sbin/scsi_id -g -u -d /dev/sdc
/sbin/scsi_id -g -u -d /dev/sdd
/sbin/scsi_id -g -u -d /dev/sde
/sbin/scsi_id -g -u -d /dev/sdf
/sbin/scsi_id -g -u -d /dev/sdg

-Above the command execute not showing any scsi_id for udev rule. I'm not testing much more but find some doc and fix this issue on above linux versions.

- Adding below rules into "/etc/udev/rules.d/50-udev.rules" in my case my OS version is 5. For more detail follow oracle-base.

- No execute again below the command and wondering got the output of scsi_id.

- Creating a file and insert below commands into this file "vim /etc/udev/rules.d/99-oracle-asmdevices.rules"

- Add the following to the "/etc/scsi_id.config" file to configure SCSI devices as trusted. Create the file if it doesn't already exist.
options=-g

- Execute below commands
/sbin/partprobe /dev/sdb1
/sbin/partprobe /dev/sdc1
/sbin/partprobe /dev/sdd1
/sbin/partprobe /dev/sde1
/sbin/partprobe /dev/sdf1
/sbin/partprobe /dev/sde1

# #OL5 and OL6
# /sbin/start_udev
ls -lrt /dev/asm*
Now proceed your next action plan for node 2.
