Chapter 3. Implementing the INRANGE FC/9000 Fibre Channel Director 227
In our example, we have four loop devices attached to one director port. This is
shown in Figure 3-46.
Figure 3-46 IN-VSN: Bypassing loop devices
We have decided that device 3 should not be seen in the fabric. To achieve this
kind of filtering, device 3 must be disabled and thereby set to Bypassed. In this
case, it means that a bypassed device is disabled from being used in the fabric.
This does not change the availability of the external Arbitrated Loop itself. For
instance, even if a bypassed device fails it might affect the other external loop
members as well. So, take into account that this kind of bypassing is just a way of
filtering but not necessarily an improvement of the availability.
To disable a particular device select it in the Loop Devices menu of the specific
director port. Click Disable to change its state to Bypassed.
