Disabling an S-VOL

Assigning a read-only or protect attribute is one of the ways to prevent data in a volume from being overwritten by replication software. Volumes having the read-only or protect attribute are not only protected against these copy operations, but are also protected against any other form of write operations.

To protect a volume only from copy operations, you must ensure that the volume has the read/write attribute then assign the S-VOL Disable attribute to the volume. This setting prohibits the volume from being used as a secondary volume for copy operations.

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 on Storage Navigator secondary windows and Modify mode, see the Hitachi Device Manager - Storage Navigator User Guide.

To disable an S-VOL:

  1. Perform one of following to display the Data Retention window.

To use a volume as an S-VOL, ensure that the volume has the read/write attribute then assign the S-VOL Enable attribute to the volume.
