- Allow/deny NFS share access
* IP access rules are required for NFS share access
* User access rules are not allowed for NFS shares
* Access level (RW/RO) is ignored
* Shares created from snapshots are always read-only
* Shares not created from snapshots are read-write (and subject to ACLs)
- Allow/deny CIFS share access
* Both IP and user access rules are required for CIFS share access
* CIFS shares require user access rules.
* User access requires a 3PAR local user (LDAP and AD is not yet supported)
* Access level (RW/RO) is ignored
* Shares created from snapshots are always read-only

created. Networking must be configured to allow connectivity from clients to
shares.

effect.

The HPE 3PAR will do additional validation at share creation time. Refer to
HPE 3PAR CLI help for more details.
Delete Nested Shares
--------------------
When a nested share is deleted (nested shares will be created when
``hpe_3par_fstore_per_share`` is set to ``False``), the file tree also
attempts to be deleted.
With NFS shares, there is no additional configuration that needs to be done.
For CIFS shares, ``hpe3par_cifs_admin_access_username`` and
``hpe3par_cifs_admin_access_password`` must be provided. If they are omitted,
the original functionality is honored and the file tree remains untouched.
``hpe3par_cifs_admin_access_domain`` and ``hpe3par_share_mount_path`` can also
be specified to create further customization.
