Volume Clone on VM and RDM

Hi

 

We have Physical server running Informix DB, and we do daily procedure which we clone the PROD volumes and map the Clone volumes to the DEV physical server,
we create via script this steps:

 

1) Enter DB into "hot-backup" mode

2) Create snapshot

3) Exit DB from "hot-backup" mode

4) Create volume clone from the snapshot

5) Bring the Luns Online

6) Map the clone luns to the DEV server

7) Rescan the DEV server HBA

8) Activate the vg

9) Mount the Luns

 

This is run in the first time - and from second time and on , there is also steps on the DEV server:

1) De-Activate the vg

2) Remove the VG/PV

3) Unmap the luns

 

All works fine with this procedure - now we move the DEV server to be VM guest on Vmware.

 

And things not working as expected , is there automatic procedure that can also work in VM env ?
