These are so-called "fastpaths". Instead of calling "smitty" (which takes you to a main menu) and going through a series of smitty-panels you can go to a certain panel directly. If unsure, just use "smitty" and follow the panels, they are pretty self-explanatory.

Also anymore steps to follow or just updating using smitty is enough (hoping that no reboot is required)
No, that is enough. Hostname and IP address only take a "touchdown" (stop/start) of the network. Depending on the IP addresses involved you might need to change also the routing, but this need no reboot too.


Quote:
1) remove server A from network and update hostname and IP address (to Server B's hostname and IP) using smitty

2) move network connection cables from server B to server A

3) update hostname and IP of server B (to that of server A's old values)

4) attach network cables removed from server A to server B
Looks good. The only thing you have to avoid is to have the same IP address twice on the network. Pulling cables is a pretty sure way of avoiding to be on the network, regardless of the validity of the IP address. ;-))

I hope this helps.

NAME
aseqnet - ALSA sequencer connectors over network SYNOPSIS
aseqnet [remotehost] DESCRIPTION
aseqnet is an ALSA sequencer client which sends and receives event packets over network. Suppose two hosts connected by network, hostA as a server and hostB as a client. The ALSA sequencer system must be running on both hosts. For creating the server port, run the following on hostA: hostA% aseqnet sequencer opened: 128:0 Then a user client 128 with port 0 was opened on hostA. (The client number may vary.) For creating the (network-)client port, run aseqnet with the hostname of the server: hostB% aseqnet hostA sequencer opened: 132:0 Now all events sent to hostA:128:0 are transferred to hostB:132:0, and vice versa. The ports created by aseqnet can be connected arbitrary to other sequencer ports via aconnect(1). For example, to connect hostB:132:0 to a MIDI output device 65:0: hostB% aconnect 132:0 65:0 Then events to hostA:128:0 will be delivered to hostB:65:0. The following command plays MIDI on hostB. hostA% pmidi -p 128:0 foo.mid The multiple clients may exist simultaneously. If hostC is connected as a client to hostA, events from from hostA are sent to all con- nected network clients, i.e. hostB and hostC. However, only one connection is allowed from a client to a server. To disconnect network, stop all clients before server by ctrl-C or sending signal to them. The server will automatically quit. OPTIONS
-p port Specify the TCP port number or TCP service name. -s addr Subscribe to the given address for read automatically. -d addr Subscribe to the given address for write automatically. -v Verbose mode. SEE ALSO
