A number of methods are available to move between 3270 station connections and TCP/IP 
LMU network attachment. StorageTek recommends cycling the HSC as the preferred 
process to transition between 3270 and TCP/IP. However, the following procedures 
offer alternative ways to accomplish the transition.

Note: The host ACS client must be upgraded to VM 4.0 or higher and must be running 
IBM TCP/IP.

 1. After the hardware modification to the LMU has been made to support network 

communications, vary the stations offline. 

 1. Users can also vary the ACS offline. 

 2. Station addresses specified in the LIBGEN SLISTATN macro do not have to be 

removed for the HSC to communicate to the LMU using TCP/IP.

 2. Load the LMUPDEF statements containing the LMUPATH parameters that specify 

the hostname or IP address for each ACS. 

StorageTek recommends that the LMUPDEF statement be specified in the 
initialization parameters, however, this statement can be issued from the console as 
well.

 3. Use the Vary ACS command to bring each ACS online. Message SLS0054I indicates 

that the ACS is online. After all ACSs to be network-attached are online, the HSC is 
ready for processing.

 1. Vary the ACS offline.

 2. Load an LMUPDEF control statement that includes either an empty data set (no 

statements) or a data set that only contains an OPTion TITLE statement.

 3. Either vary the ACS online, or vary the 3270 station addresses online.
