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.
During automatic SVOL creation in a pair setup, the system provisions a single secondary host group/iSCSI target.
The ShadowImage pair supports Fibre Channel, NVMe over FC, NVMe over TCP, and iSCSI protocols.
In Direct mode, you can create a ShadowImage pair without specifying a secondary volume ID. Instead, provide the secondary pool ID in the specification. Ansible then automatically creates the S-VOL and assigns it to the same NVMe subsystem, host group, and iSCSI target as the P-VOL.
For Create a ShadowImage pair for an existing secondary volume
1. When creating a ShadowImage pair, if the primary volume (P-VOL) is the same, use a different copy group name. If the P-VOL is different, you may reuse the same copy group name. The copy pair name must always be unique.
For Migrate ShadowImage pair
1. Once the data copy and synchronization between the source and target volumes are complete, the LDEV ID and host I/O of the source volume are swapped with those of the target volume. From the host perspective, the volume and path settings remain unchanged. However, the actual data now resides on the volume prepared for migration.
For Cancel Migration of ShadowImage Pair
1. If a pair migration is canceled, its status changes to SMPL, allowing you to restart the migration process.
For Create ShadowImage pair for an existing secondary volume for migration
1. When a volume migration pair is created, its status is set to SMPL. Data remains unchanged until the migration process begins.
For Create ShadowImage pair for non-existing secondary volume for migration
1. The S-VOL will be automatically created and mapped to same NVMe subsystem, host group, and iSCSI as the P-VOL. When a volume migration pair is created, the pair status is SMPL. Data is not copied until migration is performed.
