The Create Online Migration Pair service template runs from the creation of zones to the creation of copy pairs for online host migration through Configuration Manager. After this service is complete, you must submit the Migrate Data for Online Migration Pair service to complete the migration.
When using this template, be aware of the following:
- The Online Migration with Configuration Manager service template that existed in v10.5.1 or earlier has been split into two service templates: Create Online Migration Pair and Migrate Data for Online Migration Pair. We recommend that you use the new service templates.
- In the configuration where the source volumes have clone pairs, before running the tasks, wait a few minutes after the clone process, or update the storage system cache of configuration information.
- In the configuration where the source volumes have clone pairs, make sure that no secondary volume of the clone pairs is included in the source volumes, and that no secondary volume of the clone pairs is allocated to the selected host as source hosts.
- When you use the Capacity Saving settings, remember that Capacity Saving works even when copying data by GAD, except when After migration is selected for the Set Capacity Saving property. See "About adaptive data reduction" in the Provisioning Guide for your storage system in advance.
- By default, this service automatically enables the host mode option "88. Port Consolidation" for the target host groups when the migration is performed. This lets you specify the same port on the target storage system even if there are multiple source storage systems for the same server. In v10.9.3 or later, you can disable this function by unchecking the "Set Host Mode Option 88 to Host Groups automatically" option.
- When you create a new host group, the host group number of the specified resource group is given priority. If the host group numbers that are registered in the specified resource group are insufficient, the host group number in the resource group named "meta_resource" is used.
- If the Use Diskless Quorum option is enabled and the task fails and one of the following conditions are met, the automatically created Diskless Quorum might remain. In this case, check the Quorum ID shown in the message and manually delete the Diskless Quorum:
- KNAE07604-I is not output to the task log. This message is output for the source and target storage systems respectively.
- KNAE07606-I is output to the task log.
- The features integrating with FC switches are not supported when you select the "Host Mappings" option for "Mappings" in Target Settings. When you use any feature integrating with FC switches such as zoning, select the "Storage Port Mappings" option for "Mappings".
