求助：AS4 SCSI故障

submarineLv

服务器上面跑Squid，在Squid重启的时候，有写硬盘的操作，导致某个SCSI硬盘无法访问，查看日志/var/log/message,查看到错误的信息是：
Oct 13 09:36:33 HostName kernel: mptbase: ioc1: IOCStatus(0x0047): SCSI Protocol Error
Oct 13 09:36:33 HostName kernel: mptbase: ioc1: IOCStatus(0x0043): SCSI Device Not There
Oct 13 09:36:33 HostName kernel: SCSI error : <1 0 2 0> return code = 0x10000
Oct 13 09:36:33 HostName kernel: mptbase: ioc1: IOCStatus(0x0043): SCSI Device Not There
Oct 13 09:36:33 HostName kernel: SCSI error : <1 0 2 0> return code = 0x10000
Oct 13 09:36:34 HostName kernel: mptbase: ioc1: IOCStatus(0x0043): SCSI Device Not There
Oct 13 09:36:34 HostName kernel: SCSI error : <1 0 2 0> return code = 0x10000

Oct 13 09:36:34 HostName kernel: SCSI error : <1 0 2 0> return code = 0x10000


而过一些时候，内核就自动恢复了SCSI，也就可以访问这个磁盘了，相关的信息如下：
Oct 13 10:16:34　sc37 kernel: Attached scsi generic sg0 at scsi1, channel 0, id 1, lun 0,  type 0
Oct 13 10:16:34 sc37 kernel: Attached scsi generic sg1 at scsi1, channel 0, id 2, lun 0,  type 0


已经百度了，没有找到类似的错误。
请帮忙分析一下出错的原因，解决的办法是什么。。
谢谢
