shall I use rescan-sci?

You should rescan your scsi and make your linux see the device.  you should see that disk in fdisk output, then you partition it, create a filesystem on it and then you mount.
If you have multipath, then you should configure multipath on the way as well.

Thanks for the update. Should I stop all services before running the rescan-scsi-bus.sh script?

You dont need to stop the services while scanning scsi. See the following;
