rhel6.3挂载HP-EVA6400磁阵

要求：rhel6.3挂载HP磁阵上的2个500G vdisk

1.安装部署multipath
yum search multipath
yum install device-mapper-multipath.x86_64

找到multipath.conf文件，然后复制到/etc/下
# find / -name "multipath.conf"
/usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf
# cp /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf /etc/
编辑 multipath.conf
vim /etc/multipath.conf
在最后加入下面一段
device {
vendor “HP”
product "HSV20|HSV300|HSV40"
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
prio_callout "/sbin/mpath_prio_alua /dev/%n"
hardware_handler "0"
path_selector "round-robin 0"
path_grouping_policy group_by_prio
failback immediate
rr_weight uniform
rr_min_io 100
no_path_retry 18
path_checker tur
}

chkconfig multipathd on
service multipathd start

查看存储映射过来的磁盘，执行如下2个命令
(说明：磁阵上面vdisk划分省略，大家可以参考我的另外一个博文)

上面显示的为存储路径聚合，mpathc mpathd 为新添加磁盘，如果查看不到，果断reboot。

# pwd
/dev/mapper
#ls
controlmpathcmpathdvg00-lvhomevg00-lvrootvg00-lvusr   vg00-lvvar

2.划分LVM磁盘：
过程省略不会的可以去看下fdisk命令，
要注意的是先分扩展分区(Extended)，然后在分lvm，选8e
mpathd一样的方法划分
# fdisk /dev/mapper/mpathc

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
      switch off the mode (command 'c') and change display units to
      sectors (command 'u').

Command (m for help): p

Partition 5 does not start on physical sector boundary.

划分完毕，w保存退出后，执行partprobe（或者reboot），然后在/dev/mapper下查看

# pwd
/dev/mapper
#ls
controlmpathcmpathcp1mpathcp5    mpathdmpathdp1mpathdp5
vg00-lvhomevg00-lvrootvg00-lvusr   vg00-lvvar

mpathcp5 mpathdp5 为划分出来的lvm分区

创建lvm
1）创建pv
   pvcreate /dev/mapper/mpathcp5 /dev/mapper/mpathdp5         #pvdisplay查看
   Writing physical volume data to disk "/dev/mapper/mpathcp5"
   Physical volume "/dev/mapper/mpathcp5" successfully created
   Writing physical volume data to disk "/dev/mapper/mpathdp5"
   Physical volume "/dev/mapper/mpathdp5" successfully created
2) 创建vg
   vgcreate ORAVG01 /dev/mapper/mpathcp5 /dev/mapper/mpathdp5 #vgdisplay查看
3) 创建lv
   lvcreate -L 999G -n ORADATALV01 ORAVG01
4) 创建文件系统
   mkfs.ext4 /dev/mapper/ORAVG01-ORADATALV01
5) 挂载
   创建挂载目录 mkdir /oradata01
   vim /etc/fstab
   /dev/mapper/ORAVG01-ORADATALV01 /oradata01      ext4    defaults      0 0
   保存退出
   mount -a 如果没有报错 执行df -h查看文件系统是否挂载到了对应的目录
   /dev/mapper/ORAVG01-ORADATALV01
                     984G200M934G   1% /oradata01
