SRM DR LUNs are visible to the host but others not

Hi

I have configured SRM with recoverpoint to handle VM failover and its working perfectly, my worry is that the LUNs that are presented to the DR host are visible to the host while others are not.The LUNs that are not visible become visible only during DR or SRM failover without my intervention, I would like to keep it this way to avoid "mistakes" of mounting the DR LUNs. Is there something I am missing in this setup to make sure the LUNs do not appear when scanned but only appear during SRM failover operations?

Kindly need your help

Regards
