Notes

Note

• The output parameters entitlement_status, subscriber_id, and partner_id were removed in version 3.4.0. They were also deprecated due to internal API simplification and are no longer supported.

• Connection type gateway was removed starting from version 3.4.0. Please use an earlier version if you require this connection type.

• Ansible modules use a technology called copy group to manage all remote replication pair types (GAD, TC, HUR). Therefore, replication pairs created by tools that do not use copy group technology are not compatible with the Ansible modules. As a result, replication pairs created without copy group technology cannot be managed by the Ansible modules.

• Before managing a TrueCopy pair through Ansible Direct Connect, you must register (or pair) the source and target storage systems in the source storage’s API server. This step is required because Ansible uses REST API calls on the backend. If you skip this step—especially if you are unfamiliar with Hitachi’s REST API—you will encounter errors when managing a TrueCopy pair through Ansible. For instructions, see Manage remote storage registration.

• Before creating a TrueCopy pair, add the P-VOL to the host group, iSCSI target, or NVM subsystem on the primary storage system. Then, identify the host group to use on the secondary storage system.

• For Create a TrueCopy pair by specifying only the required fields, by specifying all the fields, and using a range for secondary volume ID

• 1. If the P-VOL is unnamed, the S-VOL will be assigned a name in the format smrha-[ldev_id]. If the P-VOL has a name, the S-VOL should use the same name. (Here, smrha stands for Storage Module Red Hat Ansible.)

• For Expand TrueCopy pair

• 1. First, the S-VOL size is increased, followed by the P-VOL size. If the pair is in the PAIR state, it is split before resizing. Once the resize operation is complete, the pair is re-synchronized.

• 2. To use this API, enable System Option Mode (SOM) 1198 and disable SOM 1199 on both primary and secondary storage systems.
