-helpDisplay the command usage and options 
Note
  1. This command is only supported on servers where the IMM can access the RAID controller.
  2. Firmware information is displayed only for associated controllers, disks, and Flash DIMMs. Firmware information for associated pools and volumes are not displayed.
  3. Information is displayed on multiple lines due to space limitations.
  4. This command is only supported on servers that support RAID logs.
  5. This command is only supported on servers that support RAID configurations.
  6. The Enable value does not support RAID level 1 configurations.
  7. A partial list of available options are listed here. The remaining options for the storage -config vol -add command are listed in the following row.
