I have a lun serviced by mutliple paths .I had to disable one path for 
reconfiguration purpose,since I longer need it.I disabled the controller c10 
and I still get 5 paths with one path as NONAME device.

How can i remove the NONAME without a reboot?

Even vxdmpadm iostat command throws error because of the NONAME

# vxdmpadm iostat show dmpnodename=c10t1d7s2 interval=5 count=10
VxVM vxdmpadm ERROR V-5-1-8668 Invalid argument.
