Post-Configuration Steps - Using the PowerStore system This topic describes the post-configuration steps using the PowerStore system. After the host configuration is completed, you can use the PowerStore storage from the host. You can create, present, and manage volumes accessed from the host via PowerStore Manager, CLI, or REST API. Refer to the PowerStore Manager Online Help, CLI Reference Guide, or REST API Reference Guide for additional information. Presenting PowerStore Volumes to the Windows Host This topic discusses presenting PowerStore Volumes to the Windows host. When adding host groups and hosts to allow Windows hosts to access PowerStore volumes, specify Windows as the operating system for the newly-created hosts. NOTE: Setting the host's operating system is required for optimal interoperability and stability of the host with PowerStore storage. You can adjust the setting while the host is online and connected to the PowerStore cluster with no I/O impact. NOTE: Refer to the PowerStore Configuring Volumes Guide for additional information. Creating a File System This topic discusses creating a file system. File system configuration and management are out of the scope of this document. NOTE: Some file systems may require you to properly align the file system on the PowerStore volume. It is recommended to use specified tools to optimally match your host with application requirements. NOTE: Creating a file system formatting with UNMAP enabled on a host connected to PowerStore may result in an increased amount of write I/Os to the storage subsystem. It is highly recommended to disable UNMAP during file system creation. To disable UNMAP during file system creation: 1. Open a Windows CMD window on the host. 2. Run the following fsutil command to temporarily disable UNMAP on the host (before creating the file system): fsutil behavior set DisableDeleteNotify 1 3. Once file system creation is complete, reenable UNMAP by running the following command: fsutil behavior set DisableDeleteNotify 0 NOTE: To verify the current setting of the file system, run the following fsutil command: fsutil behavior query DisableDeleteNotify ● DisableDeleteNotify=0 - Indicates that the 'Trim and Unmap' feature is on (enabled). ● DisableDeleteNotify=1 - Indicates that the 'Trim and Unmap' feature is off (disabled).

Creating a File System
This topic discusses creating a file system.
File system configuration and management are out of the scope of this document.
NOTE:
Some file systems may require you to properly align the file system on the PowerStore volume. It is recommended
to use specified tools to optimally match your host with application requirements.
NOTE:
Creating a file system formatting with UNMAP enabled on a host connected to PowerStore may result in an
increased amount of write I/Os to the storage subsystem. It is highly recommended to disable UNMAP during file system
creation.
To disable UNMAP during file system creation:
1.
Open a Windows CMD window on the host.
2.
Run the following
fsutil
command to temporarily disable UNMAP on the host (before creating the file system):
fsutil behavior set DisableDeleteNotify 1
3.
Once file system creation is complete, reenable UNMAP by running the following command:
fsutil behavior set DisableDeleteNotify 0
NOTE:
To verify the current setting of the file system, run the following
fsutil
command:
fsutil behavior query DisableDeleteNotify
