Z/10 - Z/196 Migration SLES9 No Connectivity
Hello All, We are currently migrating from the z/10 hardware to a z/196. The z/196 is located on a different subnet within our internal network so I need to change IP address of each LINUX guest. I have performed the following procedure for changing an IP on a SLES9 Linux guest (since initially I can't access via PuTTy / YAST). I use ED to change the IP in /etc/sysconfig/network/ ifcfg-qeth-bus-ccw-0.0.0200 and the default gw in /etc/sysconfig/network/routes. Then I restart the server. After the Linux comes up ifconfig and the route commands are displaying the new correct information. Problem is I still have no connectivity FROM/TO hosts outside of the subnet. I can ping z/os and z/vm hosts on the same subnet but nothing outside of the subnet. Any help is appreciated.

Can the gateway access the other subnets? Is there a firewall on the other side of that gateway that might be stopping you?

Forgot to ask: Is it possible the subnet mask needs to change? Scott Rohling On Fri, Feb 25, 2011 at 7:24 AM, Scott Rohling scott.rohl...@gmail.comwrote: Can the gateway access the other subnets?

Re: Z/10 - Z/196 Migration SLES9 No Connectivity
Changed the route statement and things are looking better. Initially the z/VM IP address was set as the route gw (carry over from the z/10); that wasn't working so I changed GW to the address of the actual router on our subnet... (Could swear that I tried that already). Now the guest is pingable and the guest can ping outside the subnet. I'll post any additional issues that I encounter. Appreciate the replies so far. Thanks.

Looking for a good tutorial
Hi, I need to make a presentation describing the unique aspects of running Linux on zSeries to a few UNIX/Linux guys who don't have any mainframe background. I could throw something together myself but I figured I'd try online first to maybe save some time and effort. Any material that describes DASD utilities, IFL, memory management etc. without delving too much into Linux basics would be great. Thanks for any help.

Re: Looking for a good tutorial
I don't know what the name of the course is, any longer, but it was ZV050: Linux under z/VM... after that class I was looking at a P/390 in a lab I ran with some enthusiasm.. just before it had to be de-provisioned, yanked and scrapped. *darn*. I recall seeing a LOT of presentations that'd fulfill this... -soup On Fri, Feb 25, 2011 at 3:48 PM, Mrohs, Ray (JMD) ray.mr...@usdoj.gov wrote: Hi, I need to make a presentation describing the unique aspects of running Linux on zSeries to a few UNIX/Linux guys who don't have any mainframe background.
