求助 P570重启后硬盘不识别了！

a569021245

今天中午重启机器后发现一个硬盘不识别了，用cfgmgr命令后报如下错误

Method error (/usr/lib/methods/cfgefscsi -l fscsi0 ):
        0514-061 Cannot find a child device.
Method error (/usr/lib/methods/cfgefscsi -l fscsi1 ):
        0514-061 Cannot find a child device.
cannot open /dev/hdisk1: No such device
Please mount volume 1 on /dev/hdisk1
...and press Enter to continue installp: The specified device /dev/hdisk1
        is not a valid device or file.

问题一： 是不是硬盘坏了

还有这块盘所在的卷组也不能用了

用varyonvg命令激活vg报以下错误
0516-052 varyonvg: Volume group cannot be varied on without a
quorum. More physical volumes in the group must be active.
Run diagnostics on inactive PVs.

问题二：硬盘所在的vg该如何处理

jnwwww

可能硬盘坏了，也可能接硬盘的scsi卡出问题了。

如果vg没有重要数据，可以直接exportvg，如果有，尝试拔插该硬盘所在scsi卡及该硬盘。

首先在动手之前把现在能够得到的VG PV LV FS的有关信息尽量备份，然后再操作。
既然是硬件问题，先diag。方便的话将结果贴上来晒晒。

已经exportvg，服务器不在本地所以无法插该硬盘所在scsi卡及该硬盘。


diag的结果

  U7879.001.DQDVMLW-P1-T14-L4-L0

Has the resource been removed from the system, moved to another location
or address, or turned off?

  The resource has been turned off.
    This selection will leave the resource in the system configuration.
  The resource has been removed from the system.
    This selection will remove the resource and all of its children
    from the system configuration.
  The resource has been moved to another location within the system.
    This selection will associate any children of this resource with
    the new location. It will then remove the resource from the system
    configuration.
  The resource is present and turned on.
    This selection will determine why the resource is shown as missing.

硬盘坏了啊，换吧

hello_unix

fc光纤线路检查一下，可能是HBA卡友问题，也可能是光纤问题，也可能是存储问题
总之是光纤卡到存储控制器的这个链路有问题
去排查吧

jnwwww

检查连接存储的光纤链路相关设备及线缆。
