Use Command Line to create SM-BC issue

[AllenChang]

I try to use command line to create SM-BC

This is my command line

snapmirror create -destination-path svm1_dr:/cg/cg1_dr -source-path svm1:/cg/cg1 -cg-item-mappings vol1:@vol1_dr -policy AutomatedFailOver

And when it finish,I think it work,

but in fact,it didn't

the two lun in the two cluster,they have different UUID,

And for client to say,the client will see two different drive in OS,

and can't merge then by MPIO,

What's wrong with the command?

Thanks?

After the Snapmirror Create , the above command completed , 

snapmirror initialize -destination-path svm1_dr:/cg/cg1_dr

After the Initialize command completes 

At the Primary Cluster for snapmirror list-destination

At Secondary Cluster snapmirror show command should have similar outptu stating that the snapmirrror relationship is in InSync state

====
When the sm-bc is in healthy state (InSync State)

Below are the Primary and Secondarys LUNs from the SM-BC Relationship and the lun uuid and lun serial number will be replicated and will be the same on the primary and secondary. (for lun show -instance command output)
==========
Vserver Name: c1_vs1
LUN Path: /vol/c1_vol1/lu1
Serial Number: wtJh6?VjHVhe
LUN UUID: e04c0011-f2c7-41e4-b70b-270fd5eab797 <<< Unique
Mapped: mapped
Vdisk ID: 8071588b0000000000000000000000650cd5fd97 <<< Not Unique
ZRTO Status: primary-in-sync <<< this is the primary LUN.
Local Target Uses Offset RTPIDs: false
ZRTO Volume consensus: true
SMBC Is Source: true << since primary it is called as smbc source
SMBC Policy Type: automated-failover

====

lun show -path /vol/c2_vol1/lu1 -instance

Vserver Name: c2_vs1
LUN Path: /vol/c2_vol1/lu1
Serial Number: wtJh6?VjHVhe
LUN UUID: e04c0011-f2c7-41e4-b70b-270fd5eab797 <<< this is Unique. 
Vdisk ID: 80130e2c0000000000000000000000650cd5fd97 <<< this will be unique
ZRTO Status: secondary-in-sync <<< LUN in the Secondary
Local Target Uses Offset RTPIDs: true
ZRTO Volume consensus: false
SMBC Is Source: false <<< this is secondary hence it is called false.
SMBC Policy Type: automated-failover
