netapp lun id getting changed after recovery to DR site in SRM 5.1

Dear Team,

I am testing Vmware SRM 5.1  with Netapp simulator 8.1.2.

The setup is completed and working successfull. But I have one concern after doing the recovey.

I am using ISCSI for SAN connectilty, 2 LUNS are created ESX connectivity , 1 for datastore and second for RDM for virtual machine.

before the recovery , the luns are mapped as follows

PRIMARY SITE

DR-NETAPP> lun show -m
LUN path                            Mapped to          LUN ID  Protocol
-----------------------------------------------------------------------
/vol/vol1/ESX_LUN-DATA              IS-IG-D                 2     iSCSI
/vol/vol1/ESX_LUN1                  IS-IG-D                 1     iSCSI

DR SITE

After the disaster recovery started and VMs moved to DR site, LUN mapped number changed as follows

PR-NETAPP> lun show -m
LUN path                            Mapped to          LUN ID  Protocol
-----------------------------------------------------------------------
/vol/vol1/ESX_LUN-DATA              IS-IG                   0     iSCSI
/vol/vol1/ESX_LUN1                  IS-IG                   1     iSCSI

Is there any way to keep the same LUN id for LUN after the revocery.

regards,

sarmakumar

We've seen the same issue here on FC presented datastores and are wondering the same thing - Is there a tickbox/script/something that can say 'Fail over but keep the original lun ID'?

Cheers.

Gary.
