Parameters
Parameter |
Comments |
|---|---|
The ID of the consistency group. It can be used only for get, modify, add/remove volumes, or delete operations. |
|
The name of the consistency group. It is mandatory for the create operation. Specify either cg_name or cg_id (but not both) for any operation. |
|
Description of the consistency group. |
|
This is a list of hosts. Either the host ID or name must be provided for mapping/unmapping hosts for a consistency group. If hosts are given, then mapping_state should also be specified. Hosts cannot be mapped to a consistency group, if the consistency group has no volumes. When a consistency group is being mapped to the host, users should not use the volume module to map the volumes in the consistency group to hosts. |
|
The ID of the host. |
|
The name of the host. |
|
String variable, describes the state of hosts inside the consistency group. If hosts are given, then mapping_state should also be specified. Choices:
|
|
The new name of the consistency group, used in rename operation. |
|
The password of the Unity management server. |
|
Port number through which communication happens with Unity management server. Default: |
|
Settings required for enabling replication. |
|
Name of the destination consistency group. Default value will be source consistency group name prefixed by ‘DR_’. |
|
Id of pool to allocate destination Luns. Mutually exclusive with destination_pool_name. |
|
Name of pool to allocate destination Luns. Mutually exclusive with destination_pool_id. |
|
Details of remote system to which the replication is being configured. The remote_system option should be specified if the replication_type is |
|
IP or FQDN for remote Unity unisphere Host. |
|
Password of remote Unity unisphere Host. |
|
Port at which remote Unity unisphere is hosted. Default: |
|
User name of remote Unity unisphere Host. |
|
Boolean variable to specify whether or not to validate SSL certificate of remote Unity unisphere Host.
Choices:
|
|
The replication mode. Choices:
|
|
Type of replication. Choices:
|
|
Maximum time to wait before the system syncs the source and destination LUNs. Option rpo should be specified if the replication_mode is The value should be in range of |
|
State of the replication. Choices:
|
|
Snapshot schedule assigned to the consistency group. Specifying an empty string “” removes the existing snapshot schedule from consistency group. |
|
Define whether the consistency group should exist or not. Choices:
|
|
Tiering policy choices for how the storage resource data will be distributed among the tiers available in the pool. Choices:
|
|
IP or FQDN of the Unity management server. |
|
The username of the Unity management server. |
|
Boolean variable to specify whether or not to validate SSL certificate.
Choices:
|
|
String variable, describes the state of volumes inside consistency group. If volumes are given, then vol_state should also be specified. Choices:
|
|
This is a list of volumes. Either the volume ID or name must be provided for adding/removing existing volumes from consistency group. If volumes are given, then vol_state should also be specified. Volumes cannot be added/removed from consistency group, if the consistency group or the volume has snapshots. |
|
The ID of the volume. |
|
The name of the volume. |
