ASM下添加磁盘
linux下asm磁盘扩容，此次扩容添加4块480G磁盘
第一步：multipath -ll ： 查看多路径映射磁盘（两节点都做）
配置 /etc/multipath.conf文件，配置新加磁盘的alias 的wwid （两节点都做）
第二步：停库 （最好停库，有时候start_udev容易发生磁盘错误） （两节点都做）
第三步： 1、multipath -F ： 删除现有路径 （两节点都做）
2、multipath -v2 ： 格式化路径 两节点都做）
3、multipath -ll ： 查看多路径 （两节点都做）
[root@chicbi1 bin]# multipath -F

第四步：配置udev规则 （两节点都做），此次添加四块磁盘
for i in data4 data5 data6 data7;
do echo "KERNEL==\"dm-*\", SUBSYSTEM==\"block\", PROGRAM==\"/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/\$name\", RESULT==\"`/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/mapper/$i`\", NAME=\"asm$i\", OWNER=\"grid\", GROUP=\"asmadmin\", MODE=\"0660\"" >> /etc/udev/rules.d/-oracle-asmdevices.rules done
查看udev规则，确认配置正确： （两节点都做）
[root@chicbi1 rules.d]# cat -oracle-asmdevices.rules KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6777", NAME="asmocr1", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6832", NAME="asmocr2", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6778", NAME="asmocr3", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6774", NAME="asmdata1", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6835", NAME="asmdata2", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6775", NAME="asmdata3", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6844", NAME="asmdata4", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b6849", NAME="asmdata5", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b684b", NAME="asmdata6", OWNER="grid", GROUP="asmadmin", MODE="" KERNEL=="dm-*", SUBSYSTEM=="block", PROGRAM=="/sbin/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600a0980383046304a5d4c68436b684c", NAME="asmdata7", OWNER="grid", GROUP="asmadmin", MODE=""
