使用parted工具：
#yum install parted
#parted /dev/sdb //选择要分的硬盘
#(parted) mklabel gpt //类型GPT
Warning: The existing disk label on /dev/sdb will be destroyedand all data on this disk will be lost. Do you want to continue?
Yes/No? y //确定
#(parted) mkpart prinmary 1 -1 //将硬盘分成一个分区
#(parted) print //查看
#(parted) quit //退出Information: You may need to update /etc/fstab.
#mkfs.ext4 /dev/sdb1 //格式化文件系统为ext4
GPT（全局唯一标识磁盘分区表，适合UEFI下启动的系统）与MBR（主引导记录，适合BIOS下启动的系统）不同，GPT只有主分区，没有逻辑分区

ipmitool和megacli这两款硬件维护工具，俗称业内“倚天剑”和“屠龙刀”
#megacli -PDList -aALL
#megacli -CfgLdAdd -r1 [252:0,252:1] WB Direct -a0
#megacli -CfgLdAdd -r1 [252:2,252:3] WB Direct -a0
此时/dev/下会多出 sdb 和 sdc，再进行分区就行。
#blkid /dev/sdb
[root@node-1 ~]# parted -l （查看所有磁盘状态）
