The start volumeGroup fullProvisioning command starts a full provisioning operation on all volumes in the disk pool and optionally disables resource provisioning on the volume group.

Supported Series

This command applies to any individual storage system, including the AB6100 and AB3100 series; as long as all SMcli packages are installed.

Roles

To execute this command on an AB6100 and AB3100 storage system, you must have the Storage Admin role.

Context

The Resource Provisioning feature improves SSD wear-life and increases write performance by leaving a larger portion of the drive blocks in an unallocated state than a standard volume. A resource-provisioned volume is a thick volume in an SSD volume group or pool, where drive capacity is allocated (assigned to the volume), but the drive blocks are deallocated (unmapped) during volume creation. Drive blocks are allocated as needed to complete host write IOs. Host unmap operations can return drive blocks back to the unallocated state . Resource Provisioning also eliminates time-bound background initialization, allowing for large volumes to be initialized quickly.

Resource Provisioned volumes are supported only on SSD volume groups and pools, where all drives in the group or pool support the NVMe Deallocated or Unwritten Logical Block Error Enable (DULBE) error recovery capability. Performance improvement varies with each drive model and capacity.

The full provisioning format ensures all blocks needed by the volumes in the volume group are fully mapped on the drives. This command is only applicable to resource provisioned volume group. If the option to disableResourceProvisioning is not set to FALSE, then the volumes will still be resource provisioned and new volumes created on the volume group will be resource provisioned. If the option to disable resource provisioning is set to TRUE, then the volumes will no longer be resource provisioned and new volumes created on the volume group will not be resource provisioned.

Syntax

start volumeGroup[volumeGroupName] fullProvisioning [disableResourceProvisioning=(TRUE | FALSE)]

Parameters

Parameter Description

volumeGroup

The volume group you want to start the full provisioning operation. Enclose the volume group name in square brackets ([ ])

disableResourceProvisioning

The setting to specify if resource provisioning should be disabled after the full provisioning operation completes. To skip disabling resource provisioning, set this to FALSE. The default value is TRUE.

To re-enable resource provisioning on a volume group and all associated volumes, use the Start Volume Group Resource Provisioning command.
