Use the volumes for which LU paths or namespaces for NVMe-oF have been set to create a GAD pair. You can add LU paths or namespaces for NVMe-oF to or delete them from GAD pair volumes. However, you cannot delete the last LU path because at least one LU path must be set for GAD pair volumes.
A volume for which no LU path or namespace for NVMe-oF has been set cannot be used as a GAD pair volume.
When a port has a path defined for an LDEV with the GAD reserve attribute and you need to configure the port (delete a host group, set a command device, or change the host mode, topology, AL-PL, or transfer speed), the operation might fail if you configure more than one port at a time. For ports that have a path defined on an LDEV with the GAD reserve attribute, perform these operations on one port at a time.
