How to move ESX Farm storage group to differnt FA's

Currently we have 2 pretty huge ESX farms that have their storage group devices mapped to the same FA's (port group) on our VMAX. The FA's are being overloaded and we need to segregate the 2 ESX farms and have them on dedicated FA's I am trying to get the correct procedure to follow when doing something like this in order to mimimze/eliminate any disruptions and to make sure that the lun id's for all the devices alloacted to all the VM's in the Farms stay intact. Is the a document/procedure that anybody can provide that I can refer to? Of if anybody has done this before it would be great if you could provide the steps involved.

need to understand if he is using cascaded IG or not ..if yes your steps are not going to work, it will simply map existing devices to another set of FAs.

Currently you have 2 masking views which are  sharing the same port groups.correct ?

If you have 2 masking views and two  separate IGs (even though they contain same FA port),you can follow below steps

  1. Add new FA ports to one of the IG
  2. Make sure the new paths are reflecting from host side
  3. Remove the old FA ports from the IG

Hi Guys. Thanks fro the resplose.

Here is the view to the device on one of ESX farms. I basically want to move these

devices to an alternative port group (FA's)

No the other ESX farm is using a completely different name.I am concerned that when I move these devices to a different port group that their lun id's will change.

Here is the view for the other Farm.

so both farms are using 7E:0 and 10E:0 and you want to move one farm to another set of FAs ?

Yes. Exactly. I have done this for physical servers many times but I have never moved a whole farm and I am concerned about how the Lun ID's consistency will work when the devices are remapped to alternative FA's.

Thanks guyss for you replies. I have a feeling that I will need to use vmotion and move all the VM's off each of the ESX servers one at a time . Then move that ESX server's FA's and then move all the VM's back to that ESX server and do this for eacch of them. It sounds a bit daunting so I'd like to find an easier recommended way if this is not what I need to do?

don't worry about that anymore, any recent version of ESX does not rely on LUN id anymore, it relies on NAA address. If you still want to make sure that LUN id is the same, you can mask each individual device (probably with a script) and specify -lun parameter and give it the same address as it is on the current FAs.

You can just modify the port group on one of the farm, Add the new pair of FA's to the one of the already existing port group. Have the ESX see the LUN's through the 4 paths. After making sure  that ESX sees the LUN's over 4 paths remove the old paths seen through 7E, 10E. The host will continue to see over the new path.

Just be cautious and confirm that the ESX servers sees LUN's pver 4 paths before removing 7E:0, 10E:0. Once you are done with removing 7E:0, 10E:0 rename the Port Group to the stantards you are using consiting of new FA.

If you modify the port group by adding new FA ..that will map all devices to new FA ..i dont think that OP wants that.

Adding new FA to the port group will mask devices also.

Thanks guys. I am going to add the new FA's to the current port group and have 4 paths to the devices and then remove 7E:0 and 10E:0. The same we would do it for a regular physical server with 2 FA's / 2 HBA's and powerpath. We have put a test ESX farm in place so that we can test the procedure and document all the steps involved before we do this on the production Farm in question. I appreciate your help. Thanks.
