Description (partial)

When the boot policy contains an iSCSI boot target and nothing else, adapter firmware will never receive a request from Option ROM to populate iBFT and pass control to OS during installation.  Therefore, LUN's will never be seen during the install and only seen during boot.

2.2(1c) also tested downgrading blade/adapter to 2.1(2a), which had the same result
NetApp 8.1.2 running in 7 Mode

-confirmed that IP Subnet matches for both Target and Initiator
-confirmed this is set to native VLAN
-Option ROM successfully loads
-iSCSI ping is successful
-iscsi_get_config shows no errors
-jumbo's are disable in UCS
-ensured that initiator group on array was set to type iSCSI
-ensured boot LUN on array was set to type VMware
-ensured the initiator group was granted access to this LUN and only includes a single server for this boot LUN
