Manual hba Registartion and UCS
Hello,
We have a Cisco UCS and VNX5100 attached to a pair of FC switches. I would like to know how you can manually register the hba's of the blade so I can SAN boot and install ESXi 5.
Thanks for any info.....

Zoning will depend on you SAN topology. But let's consider you have 2 independent fabrics.
Fabric A has Brocade Switch A connected to UCS FI A
Fabric B has Brocade Switch B connected to UCS FI B
No ISL Between switches.
SPA Port 0 connected to Fabric A
SPA Port 1 connected to Fabric B
SPB Port 0 connected to Fabric A
SPB Port 1 connected to Fabric B
vHBA0 connected to Fabric A
vHBA1 connected to Fabric B
So, you Zoning should be:
Zone1 Members
vHBA0
SPA - Port 0
SPB - Port 0
Zone2 Members
vHBA1
SPA - Port1
SPB - Port1

Thanks for the reply. Do I need to add the IP information as this blade has no OS and will be the ESXi 5 host?
Thanks

ESXi still has an ip address that you use to manage the box. If you do not know the ip address right now, you can put a bogus one and change it to correct one later on.

also take a look at this document, there is a section on "boot from SAN"

ESXi has built-in Unisphere agent so once you install the system and it has IP connectivity to SPA/SPB ..it will over-ride the settings that you manually put it.

when you login to VNX, go into Connectivity Status and manualy create host initiator.

Getting closer... lol
ESXi doesn't see the LUN, so I think iy might be the masking as I have not zoned the switches until I get the LUN masking correct on the VNX first.
So the WWN/IQN I would enter on the VNX is the highlighted in the pic attached????

You can have everything configured so you boot your blade only once and start installing ESX, but from my experience, it's easier to configure boot on SAN using this steps:
1. Configure Blade Profile in the UCS (you should configure Storage WWN and LUN for Boot)
2. Boot the Blade
3. Blade WWN should now appear in the SAN switch, so you can easily configure SAN Zoning
4. Boot Blade again
5. Blade WWN should now appear in the storage, so you can easily register and configure masking.
Regards,
Rafa

WWNs look good, i don't have experience with UCS adapters though
. Once you complete zoning and masking, you need to go into your HBAs setup and enable boot Bios. That document that i mentioned above describes these steps.

Rafa, thanks this is a very good idea. How are you doing your switch zoning here is an example I was thinking about, we are using 2 brocade switches.
1 SAN zone per target/initiator WWPN pair
Example
1. Zone 1
Controller 1 port 0 Fab A
Controller 2 port 0 Fab A
ESXi-X service profile vHBA0 WWPN
2. Zone 2
Controller 1 port 1 Fab B
Controller 2 port 1 Fab B
ESXi-X service profile vHBA1 WWPN
3. Mask LUN as LUN0 to ESXi-X Service Profile vHBA0 and vHBA1 WWPNs
Thanks
