I should start off by saying that I know a lot more about linux than I do z/series hardware.... I've tried centos 3.3 and 4.4 for s390 and s390x, if it make any difference.... Trying to install 4.4 on an lpar on a z9-BC and having trouble figuring out how to get the OSA adapter working. I've been told that when I ftp-boot from the iso image, I should choose "eth" for adapter type, and enter "0xe38,0xe39,0xe3a" for the addresses. For the additional parameters, I've tried: add_parms,0x10,(0xe38,0xe3a),portname:CHIP00 portname:CHIP00 and just hitting enter (which looks like it's supposed to work with centos 4.4, but not 3.3) After subsequently entering the various IP params (addr, net addr, mask, fqdn, and so on), I typically get messages somewhat like the one below (copied verbatim from the s390x with 4.4 attempt): IPv6 over IPv4 tunneling driver divert: not allocating divert_blk for non-ethernet device sit0 qeth: loading qeth S/390 OSA-Express driver cat: /sys/devices/qeth/0xe38/if_name: No such file or directory SIOCSIFNETMASK: No such device SIOCSIFBRDADDR: No such device Can anyone shed a little light on what I should be doing? I have a feeling that I'm just not seeing the 800-lb gorilla in the room..... Thanks, -- Kelly F.
