Thank you Viktor!!
Right you are, I should have used chzdev instead of znetconf -a. The devices
are displaying as Pers YES with the lszdev command. I removed the devices from
the /etc/dasd.conf file (temporarily added them there so they wouldn't be
ignored), rebooted and they are active.
Thank you,
Bill

That's not the case. Upon reboot, the kernel command line determines the
devices seen by the operating system. In a next step the configured devices are
been freed from the ignore list. In your example the console (0009), the boot
disk (0150) and two QETH devices (0300-0302, 0700-0702) are removed from the
ignore list. If you want 1000-1002 and 2000-2002 to be persistently available
you should configure them, e.g. using chzdev(8).
