Please check if there is problem HBA settings in the vmware and let me know how to fix this.

We have two storage servers, both storage servers have 2 ControllerModule respectively, like CM0 and CM1.
These storage servers are connecting with ESXi servers via Fiber channels SAN.
and,
From ESXi server,  4 CMs are visible, as Target device, T0, T1, T2, T3.

My question is regarding this HBA settings on the vmware.
There are several esxi servers, and 1 esxi server seems to have different settings compared with another esxi servers.


When checking
vSphere client > configuration > storage adapters > 


normally,  I see each settings of CM with correspondings devices like followings,
Storage server1 CM0 is T0,
Storage server1 CM1 is T1,
Storage server2 CM0 is T2,
Storage server2 CM1 is T3,

However, only from 1 ESXi server, this sequence is upside down,

Storage server1 CM0 is T3,
Storage server1 CM1 is T2,
Storage server2 CM0 is T1,
Storage server2 CM1 is T0,

Currently, there is no problem about this,
however, in case of trouble I suspect this would cause the trouble.( or fail over would not function ?)

Please let me know why 1 esxi server has reverse order settings,
and are there any possibilities that some trouble would happen?
let me know how to fix this.

( I am sure there is no problem on the storage server and fc san switch settings )
Best regards

Check your WWNN/HBA LUN Mapping or Zone (ing) Presentation.

it looks like that HBA, is mapping to the wrong LUN IDs.
