Block storage APIs

Contributors netapp-reenu ciarm netapp-manini dmp-netapp

You can use Block Storage APIs to view and manage your block storage.

Before you create disks, you have to create block stores. When you create a disk, you have to a create host group or select an existing host group to access the disk. For more information, see Work with block storage.

Block stores

You can use Block Store APIs to retrieve and manage your block stores.

HTTP Verb Path Description Mandatory parameters/Request body

/v2.1/blockstores

You can retrieve the details of all your block stores. Retrieves details of the block stores, such as block store ID, IP address, region, zone, subnet ID, and tags.

offset: The number of items to skip before starting to collect the result set.

You can retrieve the details of a specific host group. Retrieves details of the host group, such as name, subtenant details, tenant details, zone, protocol, initiators, disks using the host groups, and tags based on the entered ID.

id: The ID of the host group.

POST

/v2.1/hostgroups

You can create a host group. Add the values in the request body to create a host group with the specified parameters, such as name, subtenant ID, zone, protocol, initiators, and tags.

name: The name of the host group.
subtenant_id: The ID of the subtenant.
zone: The name of the zone.
protocol: The storage protocol used for block device access.

Note

When adding initiators to a host group, the initiator should match the host group protocol. You should use IQNs for host groups with iSCSI protocol, and WWPNs for host groups with FC protocol.

Deleting an initiator from a host group affects all the disks to which the host group is mapped to.
