Online Migration service template prerequisites

Software prerequisites

The following software prerequisites are required for the Online Migration service template.

• Hitachi Ops Center Protector v7.0 or Hitachi Data Instance Director v6.9.4 or later
• Configuration Manager v8.6.0-00 or later
• To use Quorum less, the following conditions must be satisfied:
  • When using VSP G200, G400, G600, G800, VSP F400, F600, F800, VSP N400, N600, N800, VSP G1000, VSP G1500, or VSP F1500, enable SSL between the Configuration Manager REST API server and the storage system when registering the storage by using the Ops Center API Configuration Manager. If you register the storage from the Ops Center Automator Administration tab, choose the Enable SSL communication with SVP option.
  • Stop all CCI instances between 1020-1039 on the Ops Center API Configuration Manager server.

  • Add the Ops Center API Configuration Manager server to the Ops Center Automator Agentless Remote Connections. When adding the connection, match the IP Address/Host Name setting of the Web Service Connection with the IP Address/Host Name setting of the Agentless Remote Connection setting.

• Brocade Network Advisor version 12.4, 14.2, 14.4 (SAN System Administrator or Zone Administrator role is required)

  Required for acquiring or updating Brocade FC switch Zone information.

• Data Center Network Manager version 7.1 (network-admin role is required)

  Required for acquiring or updating Cisco FC switch Zone information.

• Ops Center Administrator v10.0.0 or later

Setup prerequisites

The following setup prerequisites are required for the Online Migration service template.

Resource prerequisites

You must create the following resources before you run this service:

• Protector-DataFlow

  Source: Specify the Protector-Source Node

  Target: Specify the Protector-Target Node

  Type: Active-Active Remote Clone (Global-active device)

  Transfer Type: Continuous

• Protector-Source Node

  Type: Hitachi Block Host

• Protector-Target Node

  Type: Hitachi Block Device

• Protector Policy

  Classifications: Physical - HitachiBlock

  Operations:

  • Type - Replicate
  • Run Options - When manually triggered
  • Source Options - Quiesce configured applications before backup
• VSM (Resource Group)

  The Resource Group name (=VSM) used in this service does not include character that are not valid in CCI.

  Because Ops Center Protector acquires Resource Group information from Command Control Interface (CCI), if the Resource Group name contains characters that are not valid in CCI, the group does not appear in Resource Group options.

• Pool

  The Pool name used in this service does not include character that are not valid in CCI.

  Because Ops Center Protector acquires Pool information from CCI, and it contains characters that are not valid in CCI, the pool does not appear in Pool options.

• When using the host selection feature, create a web service connection for Ops Center Administrator that uses System Administrator credentials.
• Import the Ops Center Protector and Ops Center Administrator server certificates.

  Secure communication (HTTPS) is required for communication between Ops Center Automator and Ops Center Protector/Ops Center Administrator.

  Therefore, you must import the Ops Center Protector and Ops Center Administrator server certificate into the Ops Center Automator Trust Store.

  For details, refer to Setting up secure communications between Automator and each product.

• Resolve the Ops Center Protector and Ops Center Administrator host name. After you import the Ops Center Protector and Ops Center Administrator server into the Ops Center Automator Trust Store, ensure that the system can resolve the Ops Center Protector and Ops Center Administrator server name.
• Create a web service connection for the BNA or DCNM server.
• Create a web service connection for the Configuration Manager REST API that uses the same credentials for each storage system managed by Ops Center API Configuration Manager.
• Verify that the common credentials used to access all storage systems are assigned the following roles:
  • Security Administrator (View and Modify)
  • Storage Administrator (Provisioning)
• If the source volumes have asynchronous remote clone pairs:
  • The Hitachi Block Device node indicating the storage system of the asynchronous remote clone destination of the migration destination volume must be registered in Ops Center Protector.
  • The journal volume that can be used in the asynchronous remote clone pair must be created in the storage system of the migration destination volume and the storage system of the asynchronous remote clone destination.
  • The zoned remote path group must be defined between the storage system of the migration destination volume and the storage system of the asynchronous remote clone destination.
• If you use the Quorum-less feature, an unused common Quorum ID must exist for both the source and target.
