The LUN numbers are also duplicated which implies two different storage arrays

Read this VMware KB which explains all of this very well: Identifying disks when working with VMware ESX

u mean to say LUN ids r de-duplicated so it's coming from two different storage .

from storage1 lun 0 to 6 are mapped to esx1. Can we map other LUNs with same LUNid to an ESX1 host from same storage1.

Hi,

Can we map other LUNs with same LUNid to an ESX1 host from same storage1.

We cannot map other LUNs with the same LUN ID on the same SAN because two controllers  cannot have the same WWPN on the same SAN.

Dear Team,

if we have allocated 0-6 luns (lun id lun1,lun2,lun,3lun4,lun5,lun6)from san1 to esx1 , then is it possible to  allocate another 0-6 luns from san1 to esx1 with same LUN id???

Hi,

The storage device reading  vmhba1:C0:T(0-9):L0 in the  example contains:

    vmhba1 - HBA (Host Bus  Adapter)           --------------- Section1
    C0 - Channel
    T9 & T7 - Target (Storage processor port)
    L0 -  LUN (Logical Unit  Number or Disk Unit)

    vmhba1 - HBA (Host Bus  Adapter)           --------------- Section2
    C0 - Channel
    T0 - Target (Storage processor port)
    L0 -  LUN (Logical Unit  Number or Disk Unit)

As ur using IBM XIV Storage and the above Target shows as 2 different ports in both the Section so there are 2 Different Storages,

But ur storage team might have merge the 2 different Storage in one using IBM Storage Virtualisation Application and Created Multiple Nodes.
