Does zipl display a boot menu?  If so, you'll need to pass root= to
zipl, not IPL.  For example, at a prompt like this:

00: zIPL v1.5.3 interactive boot menu
00:
00:  0. default (linux)
00:
00:  1. linux
00:
00: Note: VM users please use '#cp vi vmsg <input>'
00:
00: Please choose (default will boot in 15 seconds):

You'll want to enter:

#cp vi vmsg 0 %root=/dev/dasdd1

This adds root=/dev/dasdd1 to the Linux kernel parameters.  Note: The %
is an escape character to '#cp vi vmsg' which sets input to lowercase.
Otherwise root= is sent as ROOT=, which Linux doesn't like very much.

Did you try - "IPL 1490 LOADPARM root=/dev/dasd1" ? What happened?

there a way to pass a Linux boot parm, when typing IPL XXXX from VM,
such as IPL 1490 root=/dev/dasda1
