Enabling/disabling tier relocation of a DP-VOL

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

You can enable or disable tier relocation of individual DP-VOLs or on all DP-VOLs.

DP-VOLs on which tier relocation is disabled are excluded from the targets for the tier range calculation, and are not reflected in the performance information of pools. If tier relocation is disabled on all DP-VOLs in a pool, performance information of a pool is unavailable in the View Tier Properties window.
