Reserving volumes

By default, all Device Manager - Storage Navigator users with proper permissions can make LU path settings and command device settings. If you perform the following procedure in Device Manager - Storage Navigator, all users, including yourself, will not be allowed to make LU path settings and command device settings on the specified volume. RAID Manager users can still make LU path settings and command device settings on the volume.

Device Manager - Storage Navigator secondary windows must be defined for use in advance. When you select Modify from the Data Retention secondary window to disable an S-VOL, other users or programs are prevented from changing storage system settings. When you close the secondary window, Modify mode is released. For more information about Hitachi Device Manager - Storage Navigator secondary windows and Modify mode, see the Hitachi Device Manager - Storage Navigator User Guide.

  • Protecting volumes using Data Retention Utility

    After provisioning your system, you can assign access attributes to open-system volumes to protect the volumes against read, write, and copy operations and to prevent users from configuring LU paths and command devices. Data Retention Utility software is required to assign access attributes to volumes.
