A user granted the super administrator permission can use the OceanStor DeviceManager to expand LUN capacity and make expanded LUNs available to application servers.
Prerequisites
- The storage system is working properly.
- The capacity that you want to add to LUNs has been determined.
- A LUN for which Clone, LUN Copy, HyperMirror, or SmartMigration is configured cannot be expanded.
Context
- For details about how to expand the capacity of remote replication LUNs, see "Expanding Remote Replication LUNs" in the HyperReplication Feature Guide specific to your product model.
- For details about how to expand the capacity of HyperMetro LUNs, see "Expanding the Capacity of a HyperMetro LUN" in the HyperMetro Feature Guide.
Procedure
- In the navigation tree on the right, choose Provisioning > LUN.The operation path varies with user types in vStore scenarios:
- System user: Click vStore, select the desired vStore, and click Details to go to the vStore view. Choose Provisioning > LUN.
- vStore user: In the vStore view, choose Provisioning > LUN.
