Hello ,

Use lun unmap command to unmap the lun  & remap it again through lum map  /vol/volumename/qtree/lun. If  does not work try to reboot the server.

this could be production environment. so we cant able reboot and also not possible to unmap , remap LUN.

so kindly provide alternative way......
