Manual hba Registartion and UCS

not sure i am following your zoning example but what you want to do is to have each HBA zoned to SPA and SPB, something like this:

Fabric A

HBA 1 - SPA0

HBA 1 - SPB2

Fabric B

HBA 2 - SPB0

HBA 2 - SPA2

I assume that you will have multiple ESX boxes booting from VNX, as you probably know a host can only belong to one storage group, LUNs can belong to multiple storage groups. So your storage group configuration will look like this

storage group 1 -  esx1 - LUN0 (boot LUN)

                                     LUN4 (datastore LUN)                   

storage group 2 - esx2 - LUN1 (boot LUN)

                                   LUN4 (datastore LUN)

storage group 3 - esx3 - LUN2 (boot LUN)

                                    LUN4 (datastore LUN)

so each storage group has a dedicated boot LUN, it's only presented to one storage group. You will also add "datastore" LUN to every storage group. You have to make that Host ID is identical when you add these "shared" LUNs.

if system has SanCopy installed, i would not put multiple ports in one zone, they will login into each other. Don't think this is something that you want. Single initiator / single target zoning is your safest bet.

Ok so this would be 2 zones per switch (2)?

And San Copy is installed....

Agreed.

So, you zoning in my example, should look like this:

Switch A - Zone1 Members

vHBA0

SPA - Port 0

Switch A - Zone2 Members

vHBA0

SPB - Port 0

Switch B - Zone1 Members

vHBA1

SPA - Port1

Switch B - Zone2 Members

vHBA1

SPB - Port1

And from that example I do not see any Interconnects as members....

That's right. FI does not show up in the zoning.

i am not familiar with UCS servers, but on regular servers during POST ..you can select to go into HBA BIOS and configure your boot LUN.

did you enable and setup HBA bios ?

Everything works and the LUN is picked up when I install ESXi, but upon reboot it asks "to Insert Boot Media in selected Boot device...bla...bla..", I did check the boot policy and all seems ok.......

Is that in Servers - BIOS Policies some place???

This is generally related to Boot Config in Service Profile.

Considering the zoning I suggested, your blade has 4 paths to the Storage. 2 using SPA and 2 using SPB

Check what is the SP that own the LUN. Let's presume you configured as SPA.

Your boot configuration must have 2 boot options:

vHBA0 booting SPA - Port 0 WWN

vHBA1 booting SPA - Port1 WWN

Also make sure you configure BOOT LUN ID correclty. This should be the HOST LUN ID number in the VNX. The same LUN can have various Host Lun ID depending on the order you add the LUNs to the Storage Groups.
