Ok. We recently experience this when adding new storage on ESXi host takes awhile when you have multiple “new” LUNs presented on the host. The setup is common for environments with LUN replication and you would be attaching the LUNs manually on the DR site. Apparently, this is normal as ESXi is making sure that the “new” LUNs is not owned by anyone. In the wizard, it takes 30 seconds per Datas
