module: vmware_target_canonical_facts
deprecated:
  removed_in: '2.13'
  why: Deprecated in favour of C(_info) module.
  alternative: Use M(vmware_target_canonical_info) instead.
short_description: Return canonical (NAA) from an ESXi host system
description:
    - This module can be used to gather facts about canonical (NAA) from an ESXi host based on SCSI target ID.

version_added: "2.0"
author:
- Joseph Callen (@jcpowermac)
- Abhijeet Kasurde (@Akasurde)
notes:
requirements:
    - Tested on vSphere 5.5 and 6.5
    - PyVmomi installed
options:
  target_id:
    description:
    - The target id based on order of scsi device.
    - version 2.6 onwards, this parameter is optional.
    required: False
    type: int
  cluster_name:
    description:
    - Name of the cluster.
    - Facts about all SCSI devices for all host system in the given cluster is returned.
    - This parameter is required, if C(esxi_hostname) is not provided.
    version_added: 2.6
    type: str
  esxi_hostname:
    description:
    - Name of the ESXi host system.
    - Facts about all SCSI devices for the given ESXi host system is returned.
    - This parameter is required, if C(cluster_name) is not provided.
    version_added: 2.6
