ASM扩容之udev

fdisk -l|egrep 'sdax|sday|sdaz|sdba'

blkid|egrep 'sdax|sday|sdaz|sdba'

准备：格式化磁盘
fdisk /dev/sdax
fdisk /dev/sday
fdisk /dev/sdaz
fdisk /dev/sdba

第一步：修改udev -- 双节点修改
cp /etc/udev/rules.d/99-Oracle-asmdevices.rules /etc/udev/rules.d/99-Oracle-asmdevices.rules.$(date +%F)
vim /etc/udev/rules.d/99-Oracle-asmdevices.rules
KERNEL=="sdax1", NAME="asm_arch3", OWNER="oracrs", GROUP="dba", MODE="0660"
KERNEL=="sday1", NAME="asm_arch4", OWNER="oracrs", GROUP="dba", MODE="0660"
KERNEL=="sdaz1", NAME="asm_data43", OWNER="oracrs", GROUP="dba", MODE="0660"
KERNEL=="sdba1", NAME="asm_data44", OWNER="oracrs", GROUP="dba", MODE="0660"
第二步：重新加载配置文件 -- 双节点执行
udevadm control --reload-rules
第三步： -- 双节点执行
start_udev
第四步： -- 2节点执行
partprobe /dev/sdax --此步骤可以忽略 如果/dev/asm未出现再执行
partprobe /dev/sday --此步骤可以忽略 如果/dev/asm未出现再执行
partprobe /dev/sdaz --此步骤可以忽略 如果/dev/asm未出现再执行
partprobe /dev/sdba --此步骤可以忽略 如果/dev/asm未出现再执行
第五步： 图形右键挂载

alter diskgroup ARCH add disk '/dev/asm_arch3';
alter diskgroup ARCH add disk '/dev/asm_arch4';
alter diskgroup SYPRODDATA add disk '/dev/asm_data43';
alter diskgroup SYPRODDATA add disk '/dev/asm_data44';

alter diskgroup ARCH mount;
alter diskgroup SYPRODDATA mount;
