To set up the connection, perform these tasks in the RAID GUI:
• Specify the storage provisioning method
• Assign the WWPN for the HBAs in the server hosts
• Define the host group to which the server host belongs to
• Create storage groups for LUNs
• Bind storage groups to each host group across four fibre ports
In this configuration, for DG0LD0 and DG0LD1, the green path is the
active path while the red path is the standby path, when the green path
fails, the link transfroms and access will be continued by the red dotted
path; for DG1LD0 and DG1LD1, the condition is reversed.
In this configuration, each LUN is mapped to all fibre ports, one is active
path and the other is standby path. The Configuration Tasks table shown
below details each configuration task according to the example given in
Figure 5-8.
