Using the storage access control tool to enable thinly provisioned LUNs

You can use storacl.exe to set the space reservation option for any volume on a storage system. The space reservation option determines whether LUNs are fully provisioned or thinly provisioned. Thin provisioning using storacl.exe is not supported with clustered Data ONTAP 8.1.

Before you begin

About this task

You can run spacereserve help at the storacl.exe prompt to view a list of additional commands and how to use them.

Setting space reservation to True indicates that LUNs on the volume are fully provisioned, and setting space reservation to False indicates that LUNs are thinly provisioned. The default value is set to True on storage system volumes that do not have space reserve set in the ThinProvision.xml file.

Steps

  1. Run storacl.exe from your Windows host.
  2. Run spacereserve help and determine which additional commands you must run to enable thinly provisioned LUNs.

    Setting space reservation to True indicates that LUNs on the volume are fully provisioned, and setting space reservation to False indicates that LUNs are thinly provisioned.

    A file named ThinProvision.xml is created on the storage system to store the space reservation settings you specify.
