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.

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 Device Manager - Storage Navigator secondary windows and Modify mode, see the System Administrator Guide.

Before you begin

  • The Storage Administrator (Provisioning) role is required to perform this task.

  • The volume is other than the volume assigned by the accelerated compression-enabled parity group

  • 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.
