GLYPH<SM590000> VLAN tagging by default is disabled for any IP address of a node port. You can use the CLI  or GUI to optionally set the VLAN ID for port IPs on both systems in the IP partnership. GLYPH<SM590000> When a VLAN ID is configured for the port IP addresses that are used in remote copy port  groups, appropriate VLAN settings on the Ethernet network must also be configured to  prevent connectivity issues. Setting VLAN tags for a port is disruptive. Therefore, VLAN tagging requires that you stop the  partnership first before you configure VLAN tags. Restart the partnership after the  configuration is complete. The IP partnership terminology and abbreviations that are used are listed in Table 11-12. 11.8.5 IP partnership and terminology 580  Implementing the IBM System Storage SAN Volume Controller with IBM Spectrum Virtualize V8.2.1 Table 11-12 Terminology for IP partnership IP partnership terminology  Description  Remote copy group or Remote copy port group The following numbers group a set of IP addresses that are  connected to the same physical link. Therefore, only IP  addresses that are part of the same remote copy group can  form remote copy connections with the partner system:  GLYPH<SM590000> 0: Ports that are not configured for remote copy GLYPH<SM590000> 1: Ports that belong to remote copy port group 1  GLYPH<SM590000> 2: Ports that belong to remote copy port group 2  Each IP address can be shared for iSCSI host attach and  remote copy functionality. Therefore, appropriate settings must  be applied to each IP address.  IP partnership Two systems that are partnered to perform remote copy over  native IP links. FC partnership Two systems that are partnered to perform remote copy over  native FC links. Failover Failure of a node within an I/O group causes the volume access  to go through the surviving node. The IP addresses fail over to  the surviving node in the I/O group. When the configuration  node of the system fails, management IPs also fail over to an  alternative node. Failback  When the failed node rejoins the system, all failed over IP  addresses are failed back from the surviving node to the  rejoined node, and volume access is restored through  this node. linkbandwidthmbits Aggregate bandwidth of all physical links between two sites  in Mbps. IP partnership or partnership over native IP links  These terms are used to describe the IP partnership feature.  Discovery Process by which two IBM Spectrum Virtualize systems  exchange information about their IP address configuration. For  IP-based partnerships, only IP addresses configured for  Remote Copy are discovered.  For example, the first Discovery takes place when the user is  running the  mkippartnership  CLI command. Subsequent  Discoveries can take place as a result of user activities  (configuration changes) or as a result of hardware failures (for  example, node failure, ports failure, and so on).
