Detach Tape Link from Partition
The Detach Tape Link from Partition operation detaches a tape link from a partition specified by the {partition-id} portion of the request URI.
HTTP method and URI
POST /api/partitions/{partition-id}/operations/detach-tape-link
In this request, the URI variable {partition-id} is the object ID of the partition.
Request body contents
Name | Type | Rqd/Opt | Description |
---|---|---|---|
tape-link-uri | String/ URI | Required | The canonical URI of the Tape Link object to be detached from the partition. |
Description
The Detach Tape Link from Partition operation detaches a tape link from the partition specified by the {partition-id} portion of the request URI. The virtual tape resources that were created for this partition will be deleted as part of this operation.
On successful execution, the tape link is detached from the partition and the virtual tape resources created in this tape link specifically for this partition are removed. The operating system in the partition will no longer be able to access the tape library targeted by this tape link. If this operation changes the value of any property for which property-change notifications are due, those notifications are emitted asynchronously to this operation.
The URI path must designate an existing Partition object and the API user must have object-access permission to it. In addition, tape-link-uri field in the request body must designate an existing Tape Link object. If either of these conditions are not met, status code 404 (Not Found) is returned.
In addition, the API user must have action/task permissions to the Partition Details task; otherwise, status code 403 (Forbidden) is returned.
If the partition is in any of the transitional states ("starting" or "stopping") or if the CPC is not in a valid state, 409 (Conflict) status code is returned. If the partition does not have the "dpm-fcp-tape-management" feature enabled, a 409 (Conflict) status code is returned.
Authorization requirements
- Object-access permission to the Partition object designated by {partition-id}.
- Action/task permission to the Partition Details task.
