powerstore_metro_volume_group (Resource)

This resource is used to manage metro volume group replication on PowerStore. Metro replication provides synchronous replication (RPO=0) between two PowerStore clusters for disaster recovery. The resource takes an existing volume group ID and configures it as a metro volume group with a remote system. Running terraform destroy will end the metro configuration.

# Commands to run this tf file : terraform init && terraform plan && terraform apply
# This resource configures metro (synchronous) replication on an existing volume group.
# Metro replication provides RPO=0 (zero data loss) between two PowerStore clusters.
# The volume group must already exist - use powerstore_volumegroup resource to create it first.

# Example: Configure metro replication on an existing volume group
resource "powerstore_metro_volume_group" "example" {
  volume_group_id  = "volume-group-id-here"
  remote_system_id = "remote-system-id-here"

  # Optional: specify a remote appliance
  # remote_appliance_id = "remote-appliance-id"

  # Optional: control destroy behavior
  # delete_remote_volume_group = false
  # force                      = false
}

Schema

Required

  • remote_system_id (String) Unique identifier of the remote system for metro replication. The remote system must support metro volumes.
  • volume_group_id (String) Unique identifier of the existing volume group to configure as a metro volume group.

Optional

  • delete_remote_volume_group (Boolean) Whether to delete the remote volume group when ending metro configuration. Default is false.
  • force (Boolean) Force end metro even if the remote side has errors. Not recommended unless the remote is known to be down.
  • is_replication_paused (Boolean) Whether the replication is paused. When set to true, replication is paused. When set to false, replication is resumed.
  • remote_appliance_id (String) Specific remote appliance to assign the volume group. If not specified, the system chooses based on space, load, and connectivity.

Read-Only

  • data_transfer_state (String) Current data transfer state of the replication session.
  • id (String) Unique identifier of the metro replication session.
  • metro_replication_session_id (String) Unique identifier of the metro replication session assigned to the volume group.
  • remote_resource_id (String) Unique identifier of the remote storage resource.
  • state (String) Current state of the replication session.
