Yes and No

It is used to access the Specialist web interface.
The IP info is set from the front console.

We don't do this, but I believe you also use the ethernet interface to have the 
3584 access a Master Console for dial home.  See the topic "Remote Support 
through a Master Console" in the 3584 "Introduction and Planning Guide".  I 
think it says you need 2 ethernet interfaces to do this.

Curiously, there are ethernet connections in each frame with drives.  It's on a 
small box above the top most drive.  Via the console you can set IP info on 
each frames ethernet port.  You can then access the specialist from multiple IP 
addresses.  We had a issue where the specialist became unresponsive.  IBM said 
the library would need power cycled to free it up - which we couldn't do right 
then.  They then suggested just moving the IP address to one of the other 
ethernet ports and move the lan cable to that port.  This worked until we got a 
power cycle on the lib.  I found this interesting - a hung specialist in the 
first frame and working specialist when accessed via other frames.

You are correct that the ethernet connection is NOT used for library 
communications from the TSM server.  That is handled via control paths defined 
on some number of drives.  These show up as a separate device at the server.  
On AIX they show up as smcX devices.  So library communications occurs across 
the fibrechannel san.

Am I correct that the IP connection in the L23 frame is used purely for the 
Tape Library Specialist web interface, not like the 3494 where its IP 
connection was also used for management interface with the TSM servers?

My network folks want to change/move the address.
