You have to have an "active port" in that vlan which shows a connected status in order for the SVI to come up or it must be in an active trunk link . If the port that you assigned to that vlan is not active then the SVI will not come up .
Is the switchport you assigned to that VLAN up? The SVI will only go up if there is an access or trunk port up and in the STP forwarding state. If you have assigned an interface to the VLAN and it is down the SVI will remain down also.
