Linux / UNIX：Smartctl 检查 3Ware RAID 卡后面的硬盘
我有一台基于 CentOS Linux 和 FreeBSD 的服务器，使用 3Ware (9650SE-2LP) RAID 卡运行。我知道如何检查Adaptec RAID 控制器后面的硬盘，但如何使用smartctl 命令查看 3ware SCSI RAID 控制器后面的 ATA/SATA 磁盘？
您需要使用以下设备名称：
a) IDE / ATA – /dev/hd[at]
b) SCSI / SATA – /dev/sd[az]或/dev/twe[0-9]或/dev/twa[0-9]
操作方法：查看 3ware SCSI RAID 控制器后面的 ATA/SATA 磁盘
使用以下语法：
smartctl -a -d 3ware,N /dev/tweY smartctl -a -d 3ware,N /dev/twaY
参数 3ware,N，整数 N 是 3ware ATA RAID 控制器内的磁盘编号（3ware“端口”）。N 的允许值从 0 到 31（含）。您可以使用以下tw_clin 命令找出 3ware 端口并检查 RAID 卡的健康状况：
# tw_cli info
示例输出：
Ctl Model (V)Ports Drives Units NotOpt RRate VRate BBU
------------------------------------------------------------------------
c0 9650SE-2LP 2 2 1 0 1 1 -
要获取 c0 控制器的端口信息，请输入：
# tw_cli info c0
示例输出：
Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy ------------------------------------------------------------------------------ u0 RAID-1 OK - - - 232.82 W ON VPort Status Unit Size Type Phy Encl-Slot Model ------------------------------------------------------------------------------ p0 OK u0 233.81 GB SATA 0 - WDC WD2503ABYX-01WE p1 OK u0 233.81 GB SATA 1 - WDC WD2503ABYX-01WE
键入以下命令查看 3Ware RAID 卡后面硬盘的智能信息，输入：
示例输出：
# smartctl -a -d 3ware,0 /dev/twa0
# smartctl -a -d 3ware,1 /dev/twa0

请注意，如果特殊字符设备节点 /dev/twa? 和 /dev/twe? 不存在，或者存在错误的主编号或次编号，smartctl 将动态重新创建它们。通常，/dev/twa0 指第一个 9000 系列控制器，/dev/twa1 指第二个 9000 系列控制器，依此类推。同样，/dev/twe0 指第一个 6/7/8000 系列控制器，/dev/twa1 指第二个 6/7/8000 系列控制器，依此类推。
