Hi, Thanks Mike and others who helped me. Changed the VSWITCH settings and TCPIP worked !!

DTCVSW1 is vswitch controller for 0503.P00 DTCVSW2 is vswitch controller for backup device 0506.P00 OK so you do have a VSWITCH defined, and it appears to be using real OSA devices 503, 504 and 505 (with 506, 507 and 508 as the backup triplet) So for your Linux to connect to it, it would need a NICDEF. Now we see: cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 ARP=no BOOTPROTO=static IPADDR=10.68.222.22 NETMASK=255.255.255.224 NETTYPE=qeth ONBOOT=yes SUBCHANNELS=0.0.0503,0.0.0504,0.0.0505 The SUBCHANNELS variable also show devices 503, 504 and 505 - however, these are virtual devices, not real devices. If they are supposed to be real devices, then that would explain why your Linux network is not working - it's trying to get the same three real devices that the VSWITCH grabbed when z/VM IPLed. If you were trying to use real OSA devices, you might have this in your Linux virtual machine's directory entry: DEDICATE 0503 0503 DEDICATE 0504 0504 DEDICATE 0505 0505 However, if you set the real and virtual OSA addresses to be the same, then you might have something like this in the directory entry: NICDEF 0503 TYPE QDIO LAN SYSTEM VSW1 If this is the case, then you would also have to give the virtual machine access to the VSWITCH (because there is no unrestricted VSWTICHes Alan :)). So, can you show us the user directory entry for the virtual machine that is running Linux? Also, what is the output of: ==> Q VSWITCH VSW1 ACC If you're not sure how to get these, ask the z/VM sysadmin. Hope this helps.
