Description of Error:

HN4Linux联盟
 lbolt value: 18270782

   World wide name (unique identifier) for following device has HN4Linux联盟
   changed HN4Linux联盟
   nport Id = 0x13800 HN4Linux联盟
 

Probable Cause / Recommended Action:

 Unlike paralled SCSI, Fibre Channel allows easy hot-swapping of disks HN4Linux联盟
  Due to address conflicts it is possible for disks to swap loop IDs HN4Linux联盟
  accidently when re-plugging them into a hub. HN4Linux联盟
  In order to reduce the chance of user data corruption or file system HN4Linux联盟
  panics, we normally require the world wide names for a particular device HN4Linux联盟
  to stay the same. Requiring the fcmsutil replace_dsk command ensures HN4Linux联盟
  that the replacement is intentional. HN4Linux联盟
  The driver has detected a new "world-wide name" unique identifier HN4Linux联盟
  at a loop position previously occupied by a device with a different HN4Linux联盟
  identifier.HN4Linux联盟
      If this is due to a deliberate replacement of the HN4Linux联盟
      previous device, use the fcmsutil replace_dsk command HN4Linux联盟
      to allow the new device to be used. If there has HN4Linux联盟
      been no intentional replacing of any devices, check HN4Linux联盟
      for conflicts in address assignments of devices on HN4Linux联盟
      the loop.

分析:

是光纤卡报告的问题,所以应该查看与光纤卡连接的设备

HN4Linux联盟
步骤:

1.使用ioscan查看光纤卡HN4Linux联盟
#ioscan -fnCfcHN4Linux联盟
Class     I  H/W Path   Driver S/W State   H/W Type     DescriptionHN4Linux联盟
============================================HN4Linux联盟
fc        0  1/0/2/1/0  td   CLAIMED     INTERFACE    HP Tachyon XL2 Fibre Channel Mass Storage AdapterHN4Linux联盟
                       /dev/td0HN4Linux联盟
fc        1  1/0/4/1/0  td   CLAIMED     INTERFACE    HP Tachyon XL2 Fibre Channel Mass Storage AdapterHN4Linux联盟
                       /dev/td1

2.为了避免是光纤卡的问题,检查每个光纤卡:

#fcmsutil /dev/td0

                           Device ID is = 0x001029HN4Linux联盟

发现这两个光纤卡都是online状态.

3.检查光纤卡上连接的设备中到底是哪个有问题(主要担心外接存储有问题,因为这会影响应用),用ioscan查看disk和tape

#ioscan -funC diskHN4Linux联盟
发现所有外接硬盘均能认到,且,状态正常.

#ioscan -funC tapeHN4Linux联盟
发现有几个设备是NP_HW状态:HN4Linux联盟
tape     34  1/0/2/1/0.1.56.255.0.0.0  stape    NO_HW       DEVICE       HP      Ultrium 3-SCSIHN4Linux联盟

     /dev/rmt/c26t0d1BESTb   /dev/rmt/c26t0d1BESTnb

4.结论:HN4Linux联盟
确定是带机的问题.现在正有HP工程师在对带机做些操作.该EMS不是系统问题.而是td0和td1这两个光纤卡无法识别该带机.

****************************************

5.总结:HN4Linux联盟
也可以用一个相对简单的方法来检查.HN4Linux联盟
1)先看报错的设备的nportID为0x13800.HN4Linux联盟
2)其中,0x后面的1,对应的是设备地址中第一个小数点后面的1.HN4Linux联盟
3)再看nport中,1后面的38.该数值是16进制,转换成10进制,则为56.即可判断问题设备的硬件地址为1/0/4/1/0.1.56HN4Linux联盟
4)经ioscan查看,该设备为Ultrium 3的带库.HN4Linux联盟
