module: ibm_sa_vol_map
short_description: Handles volume mapping on IBM Spectrum Accelerate Family storage systems

description:
    - "This module maps volumes to or unmaps them from the hosts on
        IBM Spectrum Accelerate Family storage systems."

options:
    vol:
        description:
            - Volume name.
        required: true
        type: str
    state:
        default: "present"
        choices: [ "present", "absent" ]
        description:
            - When the state is present the volume is mapped.
                When the state is absent, the volume is meant to be unmapped.
