Note

This module is part of the hitachivantara.vspone_block collection (version 3.4.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install hitachivantara.vspone_block. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: hitachivantara.vspone_block.sds_block.hv_sds_block_compute_node.

New in hitachivantara.vspone_block 3.0.0

Synopsis

• This module allows for the creation, update and deletion of compute node, adding iqn initiators to compute node, remove iqn initiators from compute node, attach volumes to compute node, detach volumes from compute node.

• It supports various compute node operations based on the specified task level.
