Create a new storage pool

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The storage pool create command creates an SSD storage pool using a given list of spare SSDs.

When a storage pool is created, Data ONTAP splits the capacity provided by the SSDs into four equally-sized allocation units. In an HA configuration, two allocation units (containing 50% of the total capacity) are assigned to each node in the HA pair. This assignment can be modified using the storage pool reassign command.

After the storage pool is created, its allocation units can be provisioned into Flash Pool or All-Flash aggregates using the storage aggregate add-disks command and the -storage-pool parameter.

If capacity from a storage pool is already provisioned into a Flash Pool aggregate, the same storage pool cannot be used to provision an All-Flash aggregate and vice versa.

For provisioning storage pool capacity into All-Flash aggregates, the vserver option raid.storagepool.data.enable must be set to true . The storage pool data enabled mode of operation is not currently supported by OnCommand management software.

Parameters

-storage-pool <storage pool name> - Storage Pool Name

This parameter specifies the name of the storage pool that is to be created. The SSDs are partitioned and placed into the new storage pool.

{ [-nodes {<nodename>|local}] - Nodes Sharing the Storage Pool

This parameter specifies a list of nodes from which SSD disks are selected to create the storage pool. If two nodes are specified then they need to be in HA configuration. Spare disks are selected from either node or its partner or both. If this parameter is not specified, storage pool will be created by selecting disks from either the node or its partner or both from where command is run.

-disk-count <integer> - Number of Disks in Storage Pool

This parameter specifies the number of disks that are to be included in the storage pool. The disks in this newly created storage pool come from the pool of spare disks. The smallest disks in this pool are added to the storage pool first, unless you specify the -disk-size parameter.

[-disk-size {<integer>[KB|MB|GB|TB|PB]}] - Disk Size

This parameter specifies the size of the disks on which the storage pool is to be created. Disks with a usable size between 95% and 105% of the specified size are selected.

| -disk-list <disk path name>,…​ - Disk List for Storage Pool Creation }

This parameter specifies a list of SSDs to be included in the new storage pool. The SSDs must be spare disks and can be owned by either node in an HA pair.

[-simulate <true>] - Simulate Storage Pool Creation

This option simulates the storage pool creation and prints the allocation unit size that would be used for the storage pool.

Examples

The following example creates a storage pool named SP1. The storage pool contains 3 SSD disks, the spare disks selected are from either local node, or its partner or both based on spare availability.

cluster1::>  storage pool create -storage-pool SP1 -disk-count 3

The following example creates a storage pool named SP2. The storage pool contains 3 SSD disks, the spare disks selected are from either node0, or its partner node1 or both based on spare availability.

cluster1::>  storage pool create -storage-pool SP2 -disk-count 3 -nodes node0,node1

The following example creates a storage pool named SP3 from four SSDs using disk list.

cluster1::>  storage pool create -storage-pool SP3 -disk-list 1.0.13, 1.0.15, 1.0.17, 1.0.19
