You can change S-VOLs that are assigned to snapshot data. You cannot simultaneously specify and operate on both a Thin Image pair and a Thin Image Advanced pair. Specify one or the other pair.
Note: If the amount of snapshot data in selected P-VOLs or the total number of pairs in selected snapshot groups exceeds 32,768, an error message appears when attempting to perform pair tasks.

If you use CCI commands, see Pair tasks using CCI or Device Manager - Storage Navigator.

You must have the Storage Administrator (Local Copy) role.

  1. In the Explorer pane, click Storage Systems, expand the storage system tree, expand Replication, and then click Local Replication.
  2. In the Local Replication window, select a P-VOL in the TI Root Volumes tab or a snapshot group in the Snapshot Groups tab.
  3. Click Operate TI Pairs.
  4. In the TI Pairs window, click More Actions > Assign Secondary Volumes.
  5. From the Available LDEVs table, select the LDEV you want to assign as the S-VOL, and then click Set.
    The selected LDEV is displayed in the Secondary Volumes column of the Selected Pairs table.
    Note:
    • The nondisruptive migration volumes do not appear in the Available Primary Volumes table.
    • If you select a capacity in Capacity, the Available LDEVs and Selected Pairs tables display the LDEVs that match the selected capacity.
    • If you select a row in the Available LDEVs table and a row in the Selected Pairs table and then click Set, you can configure a pair.
    • If you select LDEVs that were assigned to an S-VOL with the Exclude Assigned Volumes check box unchecked, the S-VOL to which snapshot data is assigned can be changed.
    • (VSP 5000 series) If you want to change an S-VOL of a Thin Image Advanced pair to an S-VOL that is already assigned to a different pair, select the S-VOL that is already assigned to the same P-VOL from the Available LDEVs table. For the Thin Image Advanced pair, the S-VOL cannot be changed between different P-VOLs.
  6. Click Finish, and then confirm the settings.
