• If an FC switch becomes unavailable, the storage system is accessed from the switch in the other fault
domain.
• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move to
the physical ports on the other storage controller.
Steps
1. Connect each server to both FC fabrics.
2. Connect fault domain 1 (shown in orange) to fabric 1.
• Storage controller 1: port 1 to FC switch 1
• Storage controller 1: port 3 to FC switch 1
• Storage controller 2: port 1 to FC switch 1
• Storage controller 2: port 3 to FC switch 1
3. Connect fault domain 2 (shown in blue) to fabric 2.
• Storage controller 1: port 2 to FC switch 2
• Storage controller 1: port 4 to FC switch 2
• Storage controller 2: port 2 to FC switch 2
• Storage controller 2: port 4 to FC switch 2
