This read-create StorageType object records whether a QoS Shaper table row's configuration is stored in volatile, non-volatile, or permanent memory. It matters to an admin planning maintenance windows or firmware upgrades, since a shaper configured as volatile storage will not survive a reboot and would need to be reprovisioned. For example, before scheduling a device restart, an admin would check cmQosShaperStorageType on critical customer shapers to confirm they are nonVolatile and will persist across the reload.
