Oracle Linux 配置 UDEV SCSI Rules 说明

Oracle RAC中ASM 的配置可以有2种方式实现:raw和asmlib。 在实际的维护中,更推荐使用raw。

使用raw又有两种方法:使用multipath和UDEV。在RedHat 平台下参考:

Redhat 5.4 +ASM + RAW+ Oracle 10g RAC 安装文档

对于ASMLIB,参考:

RAW+ASM 的RAC 安装文档

这篇看一下Oracle Linux 系统下UDEV的配置。

参考文档:

我这里的实验平台是Oracle Linux 6.1+Virtual Box。

Oracle Virtual Box 安装使用 说明 

一.准备工作

1.1   创建共享磁盘

这里直接使用VirtualBox命令来创建。 创建之前需要先关闭虚拟机。

F:\VBox\sharedisk

1.1.2 创建虚拟介质

C:\Users\Administrator.DavidDai>cdF:\VBox\sharedisk

C:\Users\Administrator.DavidDai>F:

F:\VBox\sharedisk>VBoxManage createhd --filename asm01.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:83552343-5254-4fe0-8f4d-949389a4d528

F:\VBox\sharedisk>VBoxManage createhd --filename asm02.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:b96d5ecb-168a-4eaf-851e-0f21961dae4e

 

F:\VBox\sharedisk>VBoxManage createhd --filename asm03.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:fd7bba6c-9530-433f-a7e0-24d470ba1fb9

 

F:\VBox\sharedisk>VBoxManage createhd --filename asm04.vdi --size 5120 --format VDI --variant Fixed

0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Disk image created. UUID:3239ed0d-bd0b-4124-a389-db21ecbb15db

 

 

1.1.3 将虚拟介质匹配到虚拟机上

 

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

 

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

 

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

 

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

 

几点注意的地方:

(1)    控制器名称

我这里写的是:"SATA控制器",因为我的虚拟机是中文显示的,如下图:

 


如果是英语的,,这里名称就要写成:"SATA Controller",如:

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

 

(2)storageattach 对应的是VM中显示的虚拟机的名称,我这里OraLinuxRAC1.

 

(3)如果要将磁盘加到其他的节点上,只需要更改这里的虚拟机名称即可。如:

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