Can't see my host's wwn in 3PAR

I can't see my host's wwn in 3par , although I can see it in switch and zoning is done perfectly.

 

Here is my environment...

 

I have two c7000 enclousres and I am planning to present 3par volumes to the servers in those enclosures.

When powered on the servers I can see its wwn in switch and did zoning. (Enclosure 1 and 2 are working fine untill this step)

But when I create host in 3par , I can't see the wwn of Enclosure 1 servers (Enclosure 2 is working fine).

 

I suspect that I misconfigured VC in Enclosure 1. But I could see the wwn of Enclosure 1 servers in switch , hence assuring myself VC is not a problem.

 

Someone help me where to start my debugging ?

Re: Can't see my host's wwn in 3PAR

Check the settings for the 3par ports. Must be target, not initiator.


Hope this helps!

Re: Can't see my host's wwn in 3PAR

I checked those settings. It is not a problem as one server is working fine.

 

Additional information : I created another one server profile. So totally now I have 3 server profile. 

1 st server profile - Bay 8  : WWN can be discoverd in switch and also in 3PAR . Working fine and can assign volumes.

2nd server profile - Bay 9 : WWN can be discovered in switch , but cant see WWN in 3PAR

3rd server profile - Bay 7 : WWN cannot be seen in switch and not hence can't see in 3PAR

Re: Can't see my host's wwn in 3PAR

i had the same issue with HPUX V3 and i fixed it

1- check that zoning is done perfectly

2-from the 3PAR IMC, add manually the WWN of your two HBA (click on assign in the host wizard)

3- rescan fromthe host using #ioscan -fnNCdisk

 

and it will work

Re: Can't see my host's wwn in 3PAR

I ran into this same issue with 2 new blades. I added the wwn manually as stated in this post. However, it still not seeing hosts (see attached pic). Where exactly do I run the #ioscan -fnNCdisk command?

Only on your HP-UX system.  :-)

Re: Can't see my host's wwn in 3PAR

I am not running HP-UX. Is there any other way of accomplishing the same task without HP-UX?

Re: Can't see my host's wwn in 3PAR

For anyone else having this issue. In virtual connect manager your server ports are most likely "not logged in" under HP VC FlexFabric Module . From ESXi shell:


# esxcfg-fcoe -d vmnic2
# esxcfg-fcoe -d vmnic3

Re: Can't see my host's wwn in 3PAR

We ended up rebooting the 3Par... :O After this all WWNs were shown. No Server-Reboot, no Portdisable on Switches or 3Par helped.

I think we tried everything without success. Last option was reboot of our 3Par.
