Device hitachi_vsp0_04c6 is already imported in other disk group

The possible causes of having duplicated disk ID are

1. hardware level data mirroring

2. data copy between disks (eg.  dd data from one disk to the other)

3. SAN storage provision issue

Oradg is already imported.  When tried to import the testdg , running into the error listed below

vxdg import testdg

VxVM vxdg ERROR V-5-1-16890, Disk group import of testdg failed.
Device hitachi_vsp0_04c6  is already imported in other disk group.

Solution:

The diskid need to be clear from the disk hitachi_vsp0_03cb in order to import the diskgroup testdg with a correct publen and puboffset to preserve the data

#vxdisk -f init hitachi_vsp0_03cb format=cdsdisk publen=207294208 puboffset=65792.
 

After that, vxvm will automatic import the diskgroup with one dma show no device

Add the disk back to the testdg by running the command below:

#vxdg -g testdg -k adddisk testdg14=hitachi_vsp0_03cb

To start up all the volumes in testdg after adding the disk back to it, run

#vxvol -g testdg  startall
