RAID处理

1，查看Adapter

/opt/MegaRAID/MegaCli/MegaCli64 -cfgdsply -aALL   

指定硬盘做raid

查看新加盘的Enclosure ID 和Slot号

/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -aall | egrep "Raw|Enclosure|Slot|Firmware"

Slot Number: 3
Enclosure position: 0
Raw Size: 558.911 GB [0x45dd2fb0 Sectors]
Firmware state: Online, Spun Up
Device Firmware Level: AD02
Enclosure Device ID: 10
Slot Number: 4
Enclosure position: 0
Raw Size: 447.130 GB [0x37e436b0 Sectors]
Firmware state: Online, Spun Up
Device Firmware Level: 0100

/opt/MegaRAID/MegaCli/MegaCli64 -cfgldadd -r0(raid级别) [10(Enclosure Device ID):4(Slot Number)] WB Direct -a0(Enclosure position)
