Retrieve the migration status for an SVM

Contributors

GET /svm/migrations/{uuid}

Introduced In: 9.10

Retrieves the migration status of an individual SVM.

Important notes

  • The "migrations" object includes a large set of fields and can be expensive to retrieve.

  • REST APIs only expose a data SVM as an SVM.

  • There are subsystem specific errors that can be returned from this endpoint. If a subsystem specific error is returned and this is the first migrate operation attempt, it is embedded in one of the following errors. If a subsystem specific error is returned and this is not the first migrate operation attempt, the subsystem specific error is returned directly.

Example

Retrieving an individual SVM migration status.

  GET "/api/svm/migrations/a14ae39f-8d85-11e9-b4a7-00505682dc8b/svms/f16f0935-5281-11e8-b94d-005056b46485"

Parameters

Name Type In Required Description

uuid

string

path

True

Migration UUID

fields

array[string]

query

False

Specify the fields to return.

Response

Status: 200, Ok
Name Type Description

auto_cutover

boolean

Optional property that when set to true automatically performs cutover when the migration state reaches "ready for cutover".

auto_source_cleanup

boolean

Optional property that when set to true automatically cleans up the SVM on the source cluster after the migration cutover.

check_only

boolean

Optional property that when set to true performs only migration pre-checks not the actual migration.

current_operation

string

destination

destination

Destination cluster details for the SVM migration.

ip_interface_placement

svm_migration_ip_interface_placement

Optional property used to specify the list of source SVM's IP interface and network port pairs in the destination for migrating the source SVM IP interfaces. Note that the SVM migration does not perform any reachability checks on the IP interfaces provided.

last_failed_state

string

Indicates the state of the migration.

last_operation

string

messages

array[messages]

Errors and warnings returned/displayed during migration.

point_of_no_return

boolean

Indicates if the migration has progressed beyond the point of no return. When true, the migration cannot be aborted or paused. When false, the migration can be paused or aborted.

restart_count

integer

Number of times migrate restarted the transfer, for example, rollback to transfer after starting the cutover.

source

source

Source cluster details for the SVM migration.

state

string

Indicates the state of the migration.

throttle

integer

Optional property to specify a throttle value in KB/s for each individual volume transfer. Defaults to 0 if not set, which is interpreted as unlimited. The minimum throttle value is 4 KB/s, so if you specify a throttle value between 1 and 4, it will be treated as if you specified 4.

time_metrics

time_metrics

Various time metrics details

uuid

string

SVM migration UUID
