是一款非常老的 RAID卡型号，经过google搜索，查到可以一款软件可以监控磁盘状态：

wget http://sven.stormbind.net/mpt-status-rhel/mpt-status-1.2.0-3.el5.centos.x86_64.rpm
                  wget ftp://ftp.hosteurope.de/mirror/fedora-epel/5/x86_64/daemonize-1.5.6-1.el5.x86_64.rpm

执行命令：

mpt-status -p
                  Checking for SCSI ID:0
                  Checking for SCSI ID:1
                  Found SCSI id=1, use ''mpt-status -i 1`` to get more information.  

按照提示执行：

mpt-status -i 1
