使用parted工具：
#yum install parted
#parted /dev/sdb //選擇要分的硬盤
#(parted) mklabel gpt //類型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 //確定
#(parted) mkpart prinmary 1 -1 //將硬盤分成一個分區
#(parted) print //查看
#(parted) quit //退出Information: You may need to update /etc/fstab.
#mkfs.ext4 /dev/sdb1 //格式化文件系統為ext4
GPT（全局唯一標識磁盤分區表，適合UEFI下啟動的系統）與MBR（主引導記錄，適合BIOS下啟動的系統）不同，GPT只有主分區，沒有邏輯分區

ipmitool和megacli這兩款硬件維護工具，俗稱業內“倚天劍”和“屠龍刀”
#megacli -PDList -aALL
#megacli -CfgLdAdd -r1 [252:0,252:1] WB Direct -a0
#megacli -CfgLdAdd -r1 [252:2,252:3] WB Direct -a0
此時/dev/下會多出 sdb 和 sdc，再進行分區就行。
#blkid /dev/sdb
[root@node-1 ~]# parted -l （查看所有磁盤狀態）
