Expand a storage pool
Expands a storage pool. The operation accepts a list of system drives to be used during storage pool expansion.
HTTP request syntax (URI)
POST <base_URI>/v7/storage/storage-pools/{id}/expand
Parameters
| Name | Type | Required | Values | Description |
| id | URI_PARAM | Y | string/number | Specifies either the storage pool object ID or HNAS storage pool ID. |
| systemDrives | BODY | Y | array | System drives to be used to expand the storage pool. For rules on expansion, see examples in the note below. |
| tier | BODY | N | string | Only required when expanding a tiered storage pool. Possible values are:
|
NoteExample of systemDrives values:
- Example 1 System drive number expansion requirement: If the storage pool was initially created with 4 system drives, you need at least 4 or more system drives to expand.
- Example 2 Capacity expansion requirement: List capacity refers to the amount of storage of the drive with the lowest capacity value in the grouping. When you expand the storage pool of a series of system drives, you must increment each by the list value. As an example, consider the capacity of each drive in a grouping of 4 system drives is as follows:
- 1 GB for drive 1
- 1 GB for drive 2
- 1 GB for drive 3
- 5 GB for drive 4
