■Maximum cascading distance is ten kilometers

■In cascaded configurations, hosts cannot be connected to both switches in a single zone with storage connected, and storage cannot be connected to both switches in a single zone. In other words, a switch zone can have remote storage only or local storage only, but cannot mix the two.

■Switch-to-switch connection is supported for distance only

■Only LW GBICS are supported between switches

■Cascading is supported for nameserver zones only. These are used for Sun StorEdge T3 array and FCIP connectivity.

■A maximum of two switches can be connected for distance

■Both 8-port to 16-port and 16-port to 8-port switch connectivity is supported

Rules for Adding and Removing Devices While the Hosts are Online

You can add all initial and additional storage devices while the host is online, except the Sun StorEdge A3500 FC array, which requires rebooting the host on the first LUN addition.

In high availability configurations, where alternative methods to reconstruct the data exist, a device or path to the device can be removed. Host volume management or multi-pathing software handles this device removal. For non-available configurations, the user must ensure that no host application is configured to use the device.

In the case of a Fabric configuration (nameserver zone) the user must unconfigure the device on the host. This ensures that during the boot process the host does not attempt to probe this device to create device nodes.

For details on adding a storage device, refer to “Adding Storage Devices” on page 123. For details on removing a storage device, refer to “Removing Storage Devices” on page 124.

You can add or remove a host without shutting down the SAN.
