ML150G2无法找到第二块硬盘

[会飞的鱼520]

我有一台ML150G2服务器，突然这几天找不到第二块SCSI硬盘，在BIOS里面看不到，通过系统安装盘也无法发现。我用EZ-SCSI6.0去检查，提示：A SCSI Host Adapter with Device ID:800FH Subsystem ID:005FH is not fully supported by this application some of the Host Adapter's inforn and settings may not be available for viewing.请教下，到底是出什么问题了，急。
