  • Login using Putty to the management IP.
  • Check diskspace using the following command: aggr show_space -h
    Look for avail space and the volume name.
  • Expand the volume Volume using the following command: vol size file_server_lun_vol +200g (For 200gb expansion)
  • Get the Lun path by running the following command: Lun show
  • Resize the Lun using the following command: lun resize /vol/FILE_SERVER_LUN_vol/FILE_SERVER_LUN +200g
  • In Windows disk management: Rescan disks and expand the disk.
