Transferring operations back to the primary site if pairs were deleted

The Delete Pair by Force option of the Force Delete Pairs (TC Pairs) window of HDvM - SN must be used because the paired S-VOLs are in the SMPL state at the secondary site.

In Device Manager - Storage Navigator, connect to each primary system to make sure that all secondary systems are deleted.

• To use the same switches, change the operating mode to the opposite direction.
• To use the same extenders, change the operating mode to the opposite direction. The boxes/nodes connected to the primary system must be set to channel-mode, and the boxes/nodes connected to the secondary systems must be set to device-mode.

(VSP G/F350, G/F370, G/F700, G/F900, VSP E series) At the secondary site, set TrueCopy operations in the reverse direction.

(VSP G/F350, G/F370, G/F700, G/F900, VSP E series) At the secondary site, create a TC pair in the reverse direction, and synchronize the old P-VOL with the S-VOL.

Make sure to use Entire Volume for the Initial Copy Type option in HDvM - SN, or execute the paircreate command in CCI without specifying the -nocopy option. Confirm that the pairs are created and that status is PAIR.

If a failure occurs after the one volume capacity of a TC pair can be expanded, the swap resync operation of the TC pair cannot be performed because the capacity of both the volumes is not the same. Make sure to expand the other volume capacity so that the capacity of both the volumes is the same, and then retry the operation.

Confirm that the pairs are split and status is PSUS before proceeding. If an error occurs, resolve it before proceeding.

If a failure occurs after the one volume capacity of a TC pair can be expanded, the swap resync operation of the TC pair cannot be performed because the capacity of both the volumes is not the same. Make sure to expand the other volume capacity so that the capacity of both the volumes is the same, and then retry the operation.

• To use the same switches, change the operating mode back to the original direction.
• To use the same channel extenders, change the operating mode back to the original direction. The boxes/nodes connected to the primary system must be set to channel-mode, and the boxes/nodes connected to the secondary systems must be set to device-mode.

If all P-VOL and S-VOL are synchronized, you can use None for the Initial Copy Type option in HDvM - SN, or execute the paircreate command in CCI by specifying the -nocopy option. If P-VOL and S-VOL are not fully synchronized, use Entire Volume for Initial Copy Type.

If a failure occurs after the one volume capacity of a TC pair can be expanded, the swap resync operation of the TC pair cannot be performed because the capacity of both the volumes is not the same. Make sure to expand the other volume capacity so that the capacity of both the volumes is the same, and then retry the operation.
