连接盘阵问题 紧急求救!!!!

upup

sgi 3400 连接emc 盘阵,开始正常而且放入了大量数据,但是在重新启动后os 在/dev/dsk下找不到快设备了但是在dev/rdsk下可以看到通过prtvoc
/dev/rdsk/50060160b0204798/lun3vh/c30p780000000
pt# start    end      #blocks  type    owner
  vh 0        -1       0
/dev/rdsk/50060160b0204798/lun1vh/c30p780000000
pt# start    end      #blocks  type    owner
  vh 0        -1       0
请问是不是分区信息丢了?如何找回来?数据很重要
拜托了!谢谢!!!

EMC的数据应该不会丢，
你是把阵列当单个硬盘用？

应该试试/dev/rdsk/dkscxd0l1vh

你那个设备是原始的SCSI设备，找不到卷头的。

把hinv -c disk 结果贴上

如果你的几个Lun做了XLV卷，先别轻举妄动。
EMC有硬件RAID，数据应该是不会丢的

其中Fabric RAID lun是emc设备
使用scsicontrol -i /hw/scsi/500*/lun0vol/c30p1f80000000 返回
device is ready
但是在/dev/dsk/c500*/看不到块设备

谢谢

upup

在emc array上划分4个lun每个900G左右，在每个lun上分别创建文件系统。但是在reboot server后却只能看到裸设备，块设备却找不到

unixsam

我为你祈祷……

sgi1991

原来你在这四个Lun上都做了分区了吧？ （fx）并且都Mount上过？

如果这样，现在找不到块设备，意味着分区信息丢失，那有点问题。
或者是硬件没有准备好？用EMC的管理程看看你的这个Array有没有问题。

启动过程中有没有错误信息？

BTW: 你这机器可真过瘾，这么多存贮。
