1-18 Compaq StorageWorks Fibre Channel Troubleshooting Guide
The Storage Hub 12 is transparent to the data passing through it. It does not consume any
FC-AL addresses. Because of the intelligent signal detection tests, only valid Fibre Channel
devices will be connected to the FC-AL. When devices are added to the FC-AL, the Storage
Hub 12 will automatically test the new device and accept it into the FC-AL. Faulty devices will
be dropped by the Storage Hub 12 and dynamic node addressing will maintain the overall
FC-AL integrity.
