Important
After the library is powered on and the Fibre Channel arbitrated loop is initialized,
avoid disconnecting the drives in the library from the loop. If you need to
disconnect the library from the loop, use the utility provided with your switch or
hub to bypass the affected ports before breaking the connection. The bypass sets
the port to a non-participating state on the loop. When you reconnect the library,
use the utility to return the port to a participating state.
