- Sync a replication session.
- failover_with_sync (optional, bool, None)
If
true, Sync the source and destination resources before failing over the asynchronous replication session or keep them in sync after failing over the synchronous replication session.If
false, Failover a replication session.- failback (optional, bool, None)
- Failback a replication session.
- force_full_copy (optional, bool, None)
- Indicates whether to sync back all data from the destination SP to the source SP during the failback session. Needed during resume operation when replication session goes out of sync due to a fault.
- force (optional, bool, None)
- Skip pre-checks on file system(s) replication sessions of a NAS server when a replication failover is issued from the source NAS server.
- state (optional, str, present)
- State variable to determine whether replication session will exist or not.
- unispherehost (True, str, None)
- IP or FQDN of the Unity management server.
- username (True, str, None)
- The username of the Unity management server.
- password (True, str, None)
- The password of the Unity management server.
- validate_certs (optional, bool, True)
Boolean variable to specify whether or not to validate SSL certificate.
true- Indicates that the SSL certificate should be verified.
false- Indicates that the SSL certificate should not be verified.- port (optional, int, 443)
- Port number through which communication happens with Unity management server.
Note
- The check_mode is supported.
- The modules present in this collection named as 'dellemc.unity' are built to support the Dell Unity storage platform.
