open_iscsi – Manage iSCSI targets with Open-iSCSI

Synopsis

  • Discover targets on given portal, (dis)connect targets, mark targets to manually or auto start, return device nodes of connected targets.

Requirements

The below requirements are needed on the host that executes this module.

  • open_iscsi library and tools (iscsiadm)

Parameters

Parameter Choices/Defaults Comments
auto_node_startup
boolean
    Choices:
  • no
  • yes
Whether the target node should be automatically connected at startup.

aliases: automatic
discover
boolean
    Choices:
  • no
  • yes
Whether the list of target nodes on the portal should be (re)discovered and added to the persistent iSCSI database.
Keep in mind that iscsiadm discovery resets configuration, like node.startup to manual, hence combined with auto_node_startup=yes will always return a changed state.
login
boolean
    Choices:
  • no
  • yes
Whether the target node should be connected.

aliases: state
node_auth
string
Default:
"CHAP"
The value for discovery.sendtargets.auth.authmethod.
node_pass
string
The value for discovery.sendtargets.auth.password.
node_user
string
The value for discovery.sendtargets.auth.username.
port
string
Default:
3260

Examples

- name: Perform a discovery on 10.1.2.3 and show available target nodes
  open_iscsi:
    show_nodes: yes
    discover: yes
    portal: 10.1.2.3

# NOTE: Only works if exactly one target is exported to the initiator
- name: Discover targets on portal and login to the one available
  open_iscsi:
    portal: '{{ iscsi_target }}'
    login: yes
    discover: yes

- name: Connect to the named target, after updating the local persistent database (cache)
  open_iscsi:
    login: yes
    target: iqn.1986-03.com.sun:02:f8c1f9e0-c3ec-ec84-c9c9-8bfb0cd5de3d

- name: Disconnect from the cached named target
  open_iscsi:
