An engineer is deploying a Fabric Interconnect within a data center SAN over a Fiber Channel link in end-host mode. The hosts are connected through multiple vHBAs, each of which has been hard-pinned t
The correct answer is C. The vHBAs go down and remain down until the uplink is restored because the system cannot. In Fibre Channel End-Host Mode with static pinning, each vHBA is locked (“hard-pinned”) to its assigned uplink port. If that physical uplink fails, there’s no automatic repinning to another uplink-so the vHBA stays down until its original path comes back up.
Question
An engineer is deploying a Fabric Interconnect within a data center SAN over a Fiber Channel link in end-host mode. The hosts are connected through multiple vHBAs, each of which has been hard-pinned to a specific Fibre Channel uplink. What happens to the vHBAs if the Fibre Channel uplink port fails?
Options
- AThe vHBAs go down and remain down until the fabric interconnect mode is changed to switch
- BThe system performs repinning to an active uplink, and the vHBAs remain operational.
- CThe vHBAs go down and remain down until the uplink is restored because the system cannot
- DThe vHBAs remain operational because SAN pin groups are ignored in end host mode.
