Mutimachine blueprint MSCS

Hi

We have a VCAC and EMC ViPr environment and we wanted to automate the deployment of MSCS using muti-machine blueprint.

For this we have custom vco workflows for each of the component machine  in multi-machine blueprint and will be invoked after the machine provisioning.

1. VCO workflow tagged to the fist component machine will provision the RDM with a shared iscsi adapter.

2. VCO workflow tagged to the second  component machine will add the disk of first machine using shared iscsi adapter.

So, I want to know is there any way to pass the parameters between these two workflows are is there any better way of doing the above .

Request if anyone can help on the above.

Thanks,

Deepak.
