Udev scsi Rules configuration in Oracle Linux

The configuration of ASM in Oracle RAC can be implemented in two ways: raw and asmlib. Raw is recommended for actual maintenance.

There are two ways to use raw: multipath and UDEV. On the RedHat platform, refer:

Redhat 5.4 + ASM + RAW + Oracle 10g RAC installation documentation

For ASMLIB, refer:

RAW + asm rac installation document

In this article, let's take a look at the UDEV configuration in Oracle Linux.

Reference:

My experiment platform here is Oracle Linux 6.1 + Virtual Box.

Oracle Virtual Box installation instructions

I.Preparations

1.1 Create a shared Disk

Use the VirtualBox command to create the image. Shut down the VM before creating the VM.

F: \ VBox \ sharedisk

1.1.2Create virtual Media

1.1.3Match the virtual media to the Virtual Machine

F: \ VBox \ sharedisk> VBoxManage storageattach OraLinuxRAC1 -- storagectl "SATA controller" -- port 1 -- device 0 -- type hdd -- medium asm01.vdi -- mtype retriable

F: \ VBox \ sharedisk> VBoxManage storageattach OraLinuxRAC1 -- storagectl "SATA controller" -- port 2 -- device 0 -- type hdd -- medium asm02.vdi -- mtype retriable

F: \ VBox \ sharedisk> VBoxManage storageattach OraLinuxRAC1 -- storagectl "SATA controller" -- port 3 -- device 0 -- type hdd -- medium asm03.vdi -- mtype retriable

F: \ VBox \ sharedisk> VBoxManage storageattach OraLinuxRAC1 -- storagectl "SATA controller" -- port 4 -- device 0 -- type hdd -- medium asm04.vdi -- mtype retriable

Notes:

(1) controller name

What I wrote here is: "SATA controller", because my VM is displayed in Chinese, such:

In English, the name must be written as "SATA Controller", for example:

F: \ VBox \ sharedisk> VBoxManagestorageattach OraLinuxRAC1 -- storagectl "SATA Controller" -- port 1 -- device 0 -- type hdd -- medium asm04.vdi -- mtype retriable

(2) storageattach corresponds to the name of the VM displayed in the VM.

(3) to add a disk to another node, you only need to change the Virtual Machine name here. For example:

F: \ VBox \ sharedisk> VBoxManagestorageattach OraLinuxRAC2 -- storagectl "SATA controller" -- port 1 -- device 0 -- typehdd -- medium asm04.vdi -- mtype retriable
