● wan-com - Configuration of inter-cluster connectivity.
● local-com - Configuration of connectivity between local directors.
● front-end - Configuration of connectivity with hosts.
● back-end - Configuration of connectivity with storage arrays.
port-groups context
The port groups (or communication paths) assigned to each connectivity role (back-end, front-end, local-com or wan-com) are
contained in the port-groups sub-context of each role.
Ports named WC-00 on each cluster are collectively referred to as ip-port-group-0. There are two ip-port-group-0s, one in each
cluster. The ip-port-group-0s on each cluster form one communication channel between the clusters.
Ports named WC-01 on each cluster are collectively referred to as ip-port-group-1. There are two port-group-1s, one in each
cluster. The ip-port-group-1s on each cluster form a second communication channel between the clusters.
In the following example, a metro node Metro configuration has two back-end fc-port-groups in each cluster:
VPlexcli:/clusters/cluster-1/connectivity/back-end> cd port-groups/
VPlexcli:/clusters/cluster-1/connectivity/back-end/port-groups> ll
Name Enabled Member Port
--------------- ----------- -----------
fc-port-group-2 all-enabled IO-02
fc-port-group-3 all-enabled IO-03
If multiple clusters exist, a local port-group has an analogous port-group of the same name at the remote cluster.
A port-group contains all the ports across all directors that share these characteristics:
● serve the same role
● are the same type
● have the same port number
● are on a slic that is inserted into the same position on the respective directors
Each communication role contains a list of port-groups. Use the ll command to display a summary of the role's port-groups:
VPlexcli:/clusters/cluster-1/connectivity/wan-com/port-groups> ll
Name Enabled Member Port
--------------- ----------- -----------
ip-port-group-0 all-enabled WC-00
ip-port-group-1 all-enabled WC-01
The Enabled column shows the enabled property of each port-group:
● all-enabled - All ports in the port-group are enabled.
● all-disabled - All ports in the port-group are disabled.
● inconsistent - All member-ports do not have the same enabled status.
The Member Port column lists the name of the port that belongs to this port-group. If the port name is not the same across all
directors, each unique name will be listed.
Use the set command on the enabled property to modify the enabled status of all reachable ports in the port-group:
● set enabled all-enabled: enables all reachable ports in this port-group
● set enabled all-disabled: disables all reachable ports in this port-group
port-group subcontexts
Specific port-group sub-contexts exist for each port-type: IP (ethernet) and FC (Fibre Channel), if the corresponding ports
exist. The sub-contexts associated with a particular port-group depends on both the role the port-group serves and the type
of port contained in the port group. A port-group is composed using a port-type prefix and a port-number suffix. Port-type
prefixes are:
● FC - Fibre Channel port
● IP - Ethernet port
All port-groups contain a member-ports context that provides information about the member-port from each director.
