Replacing ESXi hosts

Hi,

We have a couple of 5.0.u3 ESXi hosts that we want to replace in a prod cluster. We were thinking of building the new hosts offline with the same name and then shutting down the old hosts and adding the new. Sounds easy enough but they're attached to a FC SAN so there's Zoning involved and that's the part we're not certain on.  

How best could we do this for folk with limited zoning knowledge.  The rest we should be fine with.

Thanks

What kind of servers do you use?
When we do this kind of activity on our Cisco UCS servers we just retain the WWPN's on the old ones and assign the same ones to new server so we won't have to re-do the zoning.
That's easy with cisco servers as they have Service profiles and the WWPN's are not hard coded on the HBA.

What kind of zoning do you guys do? Do you create aliases for WWPN's? If so it will not create any problems because the new zones will have different names and the WWPN's will be different.

Even on the storage array side it would be ok because the name you give for a server is just for identification. It would not give a conflict or would not make a difference if you give a slightly modified name.
At least that's how it works with our EMC SAN. I think that's the same with all SAN's.
Just have a good plan and do it. These kind of situations need more planning and less time to implement. As i'm not aware of the products you use i'm just giving you a solution generically.

Cheers for reply.

We're replacing some Proliant dl380 g5s with some g8s. They're attached to both an EVA4400 and a P2000.  Those Ciscos sound like the biz for the HBAs!

I don't think we can do the same with our HPs.

Hmmmm .... maybe we just get someone in to redo the zoning.

Yes you will have to re-do the zoning.
Yes i don't think HP servers are capable of it so you will have to do it the hard way.
If you plan it well and take all the correct measures you will spend very less time in doing it and will not face any issues.
