3174L has nothing to do with whether it is SNA or not, its how you config
it
also 3174R is remote and is not channel attached
on a new CPU which has not BUS/TAG you need to make sure you have a ESCON
attached 3174

Kris,
Thanks for reminding me about the 3174L (Local) vs 3174 (SNA). Was that a
3174R or just plain 3174?
With the 3174L both TCP/IP and VTAM are not required as the are LOCAL
terminals to VM.
Jim

As already replied; DDR cannot restore to a disk of another device
type. So if your input is on tape, you will need to find a system
with that type of DASD. I don't know by heart, but may DITTO is able
to restore DDR tapes to another type of disk.
If however you have a running system with different types of DASD
connected, you can use DFSMS COPY to copy CMS formatted minidisks
from one disk type to another (even from CKD to FBA). DFSMS comes
free of charge with VM, but it is only installed when you explictely
do it (DFSMS COPY is high speed, it used to be a lot faster than
DDR). If this is your case, contact me again, I have some execs to
help you during such a migration.
3174's came in two versions: a SNA one and a channel attached
version. To use the channel attached version, no extra SW is
required on VM, no TCP/IP, no VTAM either. The SNA model requires
VTAM. If you got a modern CPU (like a z series) and a not too old
z/VM, you can use the integrated 3270 console and install VM from the
HMC (hardware console). No need to search for any other 3270-like
device.
P.S. 9345's were not FBA, but CKD

I can answer the second. VTAM and TCP/IP are totally independent
on VM. TCP/IP does not use CSA in GCS as it does on OS/390
systems.
I am unfamiliar with a 9395. If it is also an FBA device, you can
restore block ranges but the entire DASD depends on the amount of
blocks. You may go smaller to larger but not larger to smaller.

Subject: Two Questions About VM
Hi List,
I don't work with VM for a long time, but now, have a friend
that ask some questions, and I don't remember very well, so,
I need a help in this list.
The first question are about DDR,
Is possible do a DDR Backup from 9345 DASD, and restore this
to a 9395 DASD ?
Another question is if need install TCP/IP under VM, using a
3174 device, is necessary have also VTAM installed under VM.
This TCP/IP will be used only for Telnet.
Thanks in advance
Sergio Lima Costa
