DD140，160，610，620，630连续重新启动的故障排除
目的
本文介绍如何解决可能是由于磁盘故障导致DD无法开机或开机循环
适用于
DD140，160，610，620，630
5.1.3.0之前的所有软件版本
原因
发生磁盘的故障
解决方案
如果DD OS系统无法启动，在单用户模式下重新启动和审查dmesg日志的磁盘错误。
查看panic警报：消息
验证panic的原因是DG0的丢失：
PANIC: dd_dgrp.c:1052 dd_dgrp_stop:: Can't tolerate essential dgrp dg0 going down
审查kern.info的命令超时的迹象：

确定问题的磁盘。在上面的例子 磁盘是1:0:0:0，scsi1 Channel 0 / Target 0 / LUN 0
转换为1.10 [SDM]磁盘。
搜寻kern.info， 1:0:0:0的最后一次出现：

一旦确定了发生“命令超时”的磁盘，请重新安装磁盘和重新启动DDR，监视引导过程。如果系统继续不启动，更换磁盘。
这是由于错误＃58936引起，这是一个驱动程序问题。升级到DDOS 5.1.3.0或更高来修复驱动程序。
