As Figure 5-5 shows, the green and the red dotted paths are both active
paths. When the green path link fails, the red dotted path will continue to
access all the storage devices without interruption.
To set up the connection, perform these tasks in the RAID GUI:
• Create virtual volumes and specify the preferred controllers
• Specify the storage provisioning method
• Specify the LUN ID and map LUNs to fiber ports
The succeeding Configuration Tasks table shows the details of each
configuration task according to the example given in Figure 5-5.
