Hi Guys,

I have a couple of questions, here are the scenario.

I have 2 ESX servers trying to boot from SAN. so i created 2 Storage Group SG_ESXA and SG__ESXB. I created 1 boot lun for each server and 1 VMFS LUN. The VMFS LUN is the same lun presented to the host and added to both SG

Here's the layout :

SG_ESXA  > ESXA > 1 Boot LUN and 1 VMFS LUN (this is the same VMFS LUN with below)

SG_ESXB  > ESXB > 1 Boot LUN and 1 VMFS LUN (this is the same VMFS LUN with above)

My question is,  can the VMFS LUN has different Host ID or must it be the same on each SG? Because right now the VMFS LUN config is :

SG_ESXA: LUN ID 1: Host ID 0 :

SG_ESXB: LUN ID 1: Host ID 2 :

is this possible?will it cause issue?must it be the same?

==============================================================================================

Moving on to replication.

I have two VNX at the same data centre and replicating thru FC.

DC1 SAN Switch

VSAN 100

VSAN 200

DC2 SAN Switch

VSAN 300

VSAN 400

so when i want to zone Mirrorview port on one VNX to another VNX, do i need to create another VSAN? or i just utilize the existing VSAN?
