查看服務器RAID卡信息的SHELL腳本及MegaCLI命令介紹
目前維護的dDell服務器，大多使用的都是LSI的MegaRAID卡。
查看系統使用的什麼RAID卡，可以使用以下命令：
# dmesg |grep -i raid # cat /proc/scsi/scsi # lspci
MegaRAID卡，可以通過官方提供的工具MegaCli來進行檢查和控制。

磁帶狀態的變化，從拔盤，到插盤的過程中：
Device |Normal|Damage|Rebuild|Normal Virtual Drive |Optimal|Degraded|Degraded|Optimal Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
磁盤各個狀態說明：
A physical disk drive property indicating the status of the drive. A physical disk drive can be in one of the following states: >Unconfigured Good A disk accessible to the RAID controller but not configured as a part of a virtual disk or as a hotspare. >Online A physical disk can be accessed by the RAID controller and is part of the virtual disk. >rebuild A physical disk to which data is being written to restore full redundancy for a virtual disk. >failed A physical disk that was originally configured as Online but on which the firmware detects an unrecoverable error. >Unconfigured bad A physical disk on which the firmware detects an unrecoverable error; the physical disk was Unconfigured Good or the physical disk could not be initialized. Disks with a status of "Unconfigured bad" cannot be used for RAID configurations. >Missing A physical disk that was Online, but which has been removed from its location. >offline The drive is offline or absent. No actions can be performed on the drive until it is back online. >Global hotspare The drive will be used to repair any array in the system that had a drive failure, if the failed drive is equal to, or smaller than the hot spare drive. >Ready The drive is online and operating correctly. >Foreign The drive is part of an array created on a different controller, or created within one enclosure and moved to another on the same controller. It can be used to create a new array after clearing configuration. >None A physical disk with the unsupported flag set. An Unconfigured Good or Offline physical disk that has completed the prepare for removal operation. >copyback A bad physical disk replaced by a good one, then hotspare will copyback data to the good one and change back to hotspare
