Can anyone tell me how to enable iscsi storage and how can I make devstack running always ( avoiding ./stack.sh everytime when i boot).

Add n-vol to ENABLED_SERVICES in your localrc:

ENABLED_SERVICES=g-api,g-reg,key,n-api,n-cpu,n-net,n-sch,n-vnc,horizon,mysql,rabbit,openstackx,n-vol

If you do this, devstack will look for a volume group named "nova-volumes," and configure nova-volume to run with that. If such a volume group does not exist, it will configure nova-volume with a file-backed volume group of the same name.

As for the second question, we are thinking about adding a flag to devstack that would preserve existing data, so that subsequent runs to stack.sh use your existing configuration. Is that what you have in mind?

Diablo dashboard didn't support volumes, if you use the current master of dashboard instead of stable/diablo you will see volumes.
