Using the storage access control tool to enable thinly provisioned LUNs

You can use the storacl.exe tool on a Windows host to set the space reservation option for any volume on a storage system to manage whether LUNs are fully provisioned or thinly provisioned.

Before you begin

Run the storage access control (storacl.exe) tool from any Windows host to create the ThinProvision.xml file on your storage system in the /etc directory of the root volume.
The executable is part of your SnapDrive installation and is located in the SnapDrive directory on your host.
HTTPS must be enabled using the options ssl.enable command and secureadmin setup ssl command on the storage system.
You must be logged in as root on the storage system.

About this task

Note: The storage system access tool provides command-line Help and usage information. Enter spacereserve help at the storacl.exe prompt for a list of additional commands and how to use them.

Step

Run storacl.exe from your Windows host, and then enter the spacereserve set command to set space reservation on the specified storage system volume to either True or False. 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.
Note: The default value is set to True on storage system volumes that do not have space reserve set in the ThinProvision.xml file.
