How can I get a uniqueID to set as disk signature?

I am creating the snapshot copy of primary disk using array CLI.

I want to access the primary disk and snapshot disk from same host. San policy is onlineALL on my host. Due to disk signature collision snapshot device is remaining in off-line state. I am looking for method/API to get uniqueID that can be set as disk signature. I think this will avoid disk signature collision.

I found that using diskpart if we online the disk, OS uniquely assign the disk signature to disk. but I would like to avoid the disk signature collision errors.

Thanks in advance.
