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 on 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
