After planning the network and services, complete specific configurations on the application server and storage systems, so that data can be migrated based on SmartVirtualization and SmartMigration.

Procedure

Change the network.
1. Connect OceanStor Dorado 6000 V6 to the existing network as the network diagram shown in Figure 4-2.
2. Create zones on the Fibre Channel switch to ensure normal communication among the HDS USP-V, S5600T, OceanStor Dorado 6000 V6, and AIX-based application server.
For details about how to create zones on the Fibre Channel switch, refer to the user manual of the Fibre Channel switch.
Log in to the S5600T, and create target LUNs for data migration.
Navigation path: Choose Storage Resources > LUNs > Create > LUN.
The preceding figure shows the parameter settings of Target_LUN_HDS1. When you create Target_LUN_HDS2, set parameters as follows:
- Set Name to Target_LUN_HDS2.
- Set Capacity to 1 TB.
Set up a logical connection between storage systems.
1. Set up a logical connection between the OceanStor Dorado 6000 V6 and the HDS USP-V.
  After you allocate the OceanStor Dorado 6000 V6 and the HDS USP-V to the same zone, the HDS USP-V automatically identifies the initiator corresponding to the OceanStor Dorado 6000 V6 and sets up a logical connection.
2. Log in to the S5600T, and set up a logical connection between the OceanStor Dorado 6000 V6 and the S5600T.
  1. Create a host group corresponding to the OceanStor Dorado 6000 V6.
    Navigation path: Choose SAN Services > Mappings > Host Groups > Create.
  2. Create a host corresponding to the OceanStor Dorado 6000 V6.
    Navigation path: Choose SAN Services > Mappings > Hosts > Create.
  3. Map the target LUNs created on the S5600T to the host corresponding to the OceanStor Dorado 6000 V6.
    Navigation path: Choose SAN Services > Mappings > Hosts, select the host whose Name is Host_1, and choose Mapping > Add LUN Mapping in the navigation bar.
Log in to the OceanStor Dorado 6000 V6, and check whether the SmartVirtualization and SmartMigration licenses are valid.
Navigation path: Choose Settings > License Management.
Use the OceanStor Dorado 6000 V6 to host LUNs created on the HDS USP-V and the S5600T.
1. Create a storage pool that is used to create eDevLUNs.
  Navigation path: Choose System > Storage Pools > Create.
2. Initiate automatic LUN scanning.
  Navigation path: Choose System > External Storage, select the remote device whose Name is HDS USP-V, and click Scan for External LUN.
3. Create eDevLUNs.
  Navigation path: Choose System > External Storage, select the remote device whose Name is HDS USP-V, and click Create eDevLUN.
  The preceding operations are performed to enable the OceanStor Dorado 6000 V6 to host LUNs created on the HDS USP-V. To enable the OceanStor Dorado 6000 V6 to host LUNs created on the S5600T, set parameters as follows:
  - Set Name of the remote device to S5600T.
  - Set WWNs of the remote LUNs to 60:02:2A:11:00:06:8d:fe:07:a4:a4:6d:26:00:00:00:75 and 60:02:2A:11:00:06:8d:fe:07:a4:a4:6d:26:00:00:00:76.
  - Set Name of eDevLUNs to eDevLUN_Target_HDS1 and eDevLUN_Target_HDS2.
  - Set Storage Pool to which the eDevLUNs belong to StoragePool1.
On the AIX-based application server, perform the following operations to stop services running on the HDS USP-V:
1. Close the database and enable the file system to go offline.
2. Delete the LUNs mapped from the HDS USP-V and the multipathing software delivered with the HDS USP-V.
  rmdev -dl hdiskX//Delete the LUNs mapped to the application server.
  
  smitty remove//Delete the multipathing software delivered with the HDS USP-V.
  
  lslpp -l | grep -i dlmanager//Check whether the multipathing software is deleted. If no command output is displayed, the multipathing software is successfully deleted.
3. Remove the AIX-based application server and the HDS USP-V from their joint zone.
4. Restart the AIX-based application server.
Enable the OceanStor Dorado 6000 V6 to take over services.
1. Install Huawei UltraPath on the AIX-based application server.
  
  For details about the operation procedure, see the relevant UltraPath user guide (applicable to the AIX operating system).
2. Log in to the OceanStor Dorado 6000 V6, and set up a mapping relationship between the AIX-based application server and eDevLUN_HDS1 as well as between the AIX-based application server and eDevLUN_HDS2.
  Perform the following operations:
  1. Create a host.
    Navigation path: Choose Services > Block Service > Hosts > Hosts > Create > Create Host.
  2. Create a host group.
    Navigation path: Choose Services > Block Service > Hosts > Host Groups > Create.
  3. Create a LUN group.
    Navigation path: Choose Services > Block Service > LUN Groups > Create.
  4. Create a mapping.
    Navigation path: Choose Services > Block Service > Hosts.
3. On the AIX-based application server, scan for LUNs and start the database.
  cfgmgr//Scan for mapped logical disks.
  
  show vlun//Query LUN information.
  
  importvg -y prod hdiskX//Import VG information into the ODM library.
  
  mount /dev/prodlv /Oracle//Mount the file system.
Use SmartMigration to set up a data migration relationship between source LUNs (eDevLUN_HDS1 and eDevLUN_HDS2) and target LUNs (eDevLUN_Target_HDS1 and eDevLUN_Target_HDS2).
Navigation path: Choose Services > Resource Tuning >SmartMigration > Create.
The preceding operations are performed to set up a data migration relationship between eDevLUN_HDS1 and eDevLUN_Target_HDS1. To set up a data migration relationship between eDevLUN_HDS2 and eDevLUN_Target_HDS2, set parameters as follows:
- Source LUN: eDevLUN_HDS2
- Target LUN: eDevLUN_Target_HDS2
- Migration speed: High
After data migration is complete, stop services running on the OceanStor Dorado 6000 V6.
1. Close the database and enable the file system to go offline.
2. Remove the OceanStor Dorado 6000 V6 and the AIX-based application server from their joint zone.
Enable the S5600T to take over services.
1. Log in to the S5600T, and set up a mapping relationship between the AIX-based application server and Target_LUN_HDS1 as well as between the AIX-based application server and Target_LUN_HDS2.
  Perform the following operations:
  1. Create a host group.
    Navigation path: Choose SAN Services > Mappings > Host Groups > Create.
  2. Create a host.
    Navigation path: Choose SAN Services > Mappings > Hosts > Create.
  3. Add LUN mappings.
    Navigation path: Choose SAN Services > Mappings > Hosts, select the host whose Name is Host_AIX1, and choose Mapping > Add LUN Mapping in the navigation bar.
2. On the AIX-based application server, scan for LUNs.
  cfgmgr//Scan for mapped logical disks.
  
  show vlun//Query LUN information.
  
  importvg -y prod hdiskX//Import VG information into the ODM library.
  
  mount /dev/prodlv /Oracle//Mount the file system.
