The wwidmgr -quickset command provides a reachability display

equivalent to entering the wwidmgr -show reachability

command. The reachability part of the display provides the

following information:

1 The worldwide name (WWN) for the storage unit that is to be

accessed. This WWN is assigned to a wwidn variable.

2 In the connected column, whether the storage unit is

currently available through the Fibre Channel host bus

adapter to controller port connection.

3 The new device name for the storage unit.

4 The Fibre Channel adapters through which a connection to the

storage unit is potentially available.

5 The port WWN of the controller ports (N_Ports) that will be

used to access the storage unit. This will show up as an Nn

variable.

b. Set the device unit number for the first cluster member system boot

disk to 106, as shown in Example 4-17.
