I just installed the latest package management tools to XIV (4.4 Build 56 for Windows, Hyper-Scale Manager 184.108.40.206) and does not allow me to map any volume manually using the GUI. The table on the right shows only the mapped LUN and not shows free addresses. I tried with an older version (4.3 Build 19 GUI) and it works properly. Manual mapping from the command line (XCLI 4.4) (map_vol vol=vol_test cluster=CL01_test lun=9) also works well.
All are XIV Gen2 version 10.2.4.e-3.
