Found the problem. I had wiped my previous installation of xCAT with the following commands:
yum erase xCAT\* rm -rf /opt/xcat /etc/xcat /root/.xcat (and a few more places) The second step removed the actual ipmitool-xcat binary, but the first step didn't clean up the corresponding RPM, so when I later reinstalled xCAT, yum did not try to reinstall ipmitool-xcat. The fix was: yum reinstall ipmitool-xcat. bmcdiscover is working beautifully now. The servers are Dell PowerEdge R230, with default user name and password. But that's now moot, of course!
