CLI to confirm unused devices by disk group.

I am looking for the correct CLI to get unused devices by disk group.

Is this possible?

I need to find unmapped volumes that are not in use by a host by disk group.

Please don't tell me about SPA etc my customer has no budget ;-) Ionix install eminent.

I have trawled through these forums and external forums.

I have also tried numerous CLI commands that don't give me the right info or fail due to my lack of experience.

V-Max 5874.248.194 SE 7.2 SMC 7.1 R5 and mirrored vols (See SMC is the problem made me lazy ;-))

Any help appreciated.

I will award points ;-)

Thanks
