I found the error, the Linux RHEL image does not have iSCSI boot and a mapping.

The iSCSI volume has RHEL on it (I used dd to copy it from an EBS instance onto the FSxN ISCSI volume). If I attach the EBS device to an instance, it boots just fine. I can see the partitions and MBR on the iSCSI volume, which I have mounted to a temp server just to investigate. My iPXE user data script is as follows; #!ipxe set initiator-iqn iqn.2010-04.org.ipxe:client123 sanboot iscsi:172.31.69.149::::iqn.1992-08.com.netapp:sn.4e1a726d7ce711ef8dbdb5f20130e1ac:vs.3 PXE seems to see the volume just fine, and boot proceeds until I get this screen (see attached). It’s a hang - could this possibly be due to the device order? I am not sure how to proceed. Thanks, Randy Seamans
