You cannot increase the size. Because your LUN is already configured with 350GB. > mpath4 (3600507630affc39e0000000000000005) dm-2 IBM,2107900 > > [size=350G][features=1 queue_if_no_path][hwhandler=0][rw] > \_ round-robin 0 [prio=4][active] > \_ 2:0:0:0 sdc 8:32 [active][ready] > \_ 2:0:1:0 sdf 8:80 [active][ready] > \_ 3:0:0:0 sdi 8:128 [active][ready] > \_ 3:0:1:0 sdl 8:176 [active][ready] But, if you really need to increase the size, backup the data, reconfigure the size disk of LUN (mpath4). Contact the storage engineer to resize the LUN. And reinitiate the multipath in your Linux machine.
