Iscsi booting vmware

I am trying to setup a UCSB to boot esxi off an iSCSI drive.  I have the iSCSI boot setup and it looks good, but when I boot ESXi, it does not show the iSCSI drive as available to install to.  Any ideas where I should be looking?

Forgot to mention, its ESXi 5.5 and UCS 2.2.2c

Are you sure that you have

Are you sure that you have end to end IP connectivity to your iSCSI storage system ?

- is the iSCSI device directly connected or via a network ?

- the iSCSI boot requires the Vlan to be native !

I would as a quick test install ESXi locally (if this is possible at all ? or on a USB, if you don't have local disks) and see whether you can see the iSCSI lun ?

There is IP connectivity.

There is IP connectivity.  The iSCSI  plan is set native and is on the same plan as the NAS (no routing).

Trying to install ESXi locally and connecting the iscsi to it.

If I install ex locally, I

If I install ex locally, I can connect to the iscsi drive I am trying to boot from.  Could it be a driver issue on the install disk?  It is the customized cisco one from vmware, ESXi-5.5.0-1746018-Custom-Cisco-

Boot policy is setup to boot

Boot policy is setup to boot iSCSI first, and it does appear to try and boot it.  Problem is the drive does not show up as an installable drive in ESXi setup program.

Maybe I miss something, but I can't find this box on the interop matrix for iSCSI boot.

This is the time where you need a protocol analyzer to see where the problem is.

You might open a TAC case, but most likely its a waste of time, see above.
