ASM使用外部冗余的安装

原创 Oracle 作者:lucyne 时间:2015-09-07 16:27:35 0 删除 编辑
我们在使用asm的时候,选择的外部冗余,也就是使用raid10,不使用asm的二路,三路镜像。

大概记录一下安装步骤

1.磁盘做raid5,在做raid5的时候可以将整个raid虎头划分为几个逻辑盘
[root@statg2 ~]# MegaCli -CfgDsply -a0
                                     
==============================================================================
Adapter: 0
Product Name: PERC H700 Integrated

==============================================================================
Number of DISK GROUPS: 1


DISK GROUP: 0
Number of Spans: 1
SPAN: 0

2.fdisk 将以下逻辑盘格式化后相当于asm单块磁盘
[root@statdb183 ~]# sfdisk -l
Disk /dev/sdc: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdd: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sde: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdh: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdg: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdf: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdi: 82698 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdb: 104433 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdj: 26108 cylinders, 255 heads, 63 sectors/track
Disk /dev/sdk: 34854 cylinders, 255 heads, 63 sectors/track
3./etc/udev/rules.d设置权限文件
[root@statdb183 rules.d]# cat 99-oracle-asmdevices.rules 
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="36b8ca3a0f2c8a9001a25e35f2c724647", NAME="asm-diskb", OWNER="grid", GROUP="asmadmin", MODE="0660"

KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="36b8ca3a0f2c8a9001a25e4cc42352604", NAME="asm-diskk", OWNER="grid", GROUP="asmadmin", MODE="0660"

4.这样就可以在安装grid软件时选择建立数据组了。
