Did you re-scan the bus for new disks?

Two additional thoughts:

multipathing requires a minimum of setup, in particular configuring the multipath.conf file. Your distro probably has a guide for that.

The command multipath -v4 will give you extremely verbose information, including devices it found and what it did with them (e.g. blacklisting them or making a multipath).
