  That day I have dealed with one case about vxvm disk group.
First of all, I tried to import oradg.

# vxdg import oradg
VxVM vxdg ERROR V-5-1-587 Disk group oradg: import failed: Disk is in use by another host
But there are no any servers including oradg imported.

Then, I tried to import oradg forcedly
# vxdg -f -C import oradg
VxVM vxdg ERROR V-5-1-587 Disk group oradg: import failed: Serial Split Brain detected. Run vxsplitlines

Now I think why the disk group can not be imported anyway?
I start to talk with the Field engineer, and discuss the server process recently. I found out some disk error happend to the exact oradg!

   I searched one relavant document from support.veritas.com, and followed by the instruction of the articles. But I could not resovle it!

    Here we should backup the disk group private slice information
# vxprivutil dumpconfig /dev/rdsk/c3t4d6s3 >/var/tmp/c4t4d6s3.bak

run explorer to collect all system configuaration, messages and so on.

Now only I can do is remove the suspective disks from oradg

# vxdisk offline c4t5d6
(some same commands ignored)

Import oradg again. Well done!
# vxdg import oradg

Now remove the defective disks
# vxdg -g oradg -k rmdisk c4t5d6
(some same commands ignored)

re-initialized the disks
vxdiskunsetup -C c4t5d6
vxdisksetup -i c4t5d6 format=sliced

# vxdg -g oradg -k adddisk oradg04=c4t5d6

# vxrecover -g oradg -sb

The end.

From the phenomenon, It maybe a VxVM 4.0 bug in my viewpoint. But not sure this
