Dear Experts,
PLease find the below screenshot and please help me with the following points
1) y it's showing the 4 paths instead of 2 paths, i mean to say it has to show the folowing
vmhba1:c0:t0:L2
vmhba2:c0:t1:L2
2) What do you mean by target?
3) what is the difference between Active / Active (I/O).
Regards

It means that both HBA's are seeing both storage controllers/processors. This is what your SAN configuration is presenting to the ESX.
2) What do you mean by target?
Target is the storage controller/processor.
3) what is the difference between Active / Active (I/O).
You probably is using FIXED multipathing policy, meaning you can only use 1 path for I/O, but the other paths are logged in and ready to receive IO in case of a failover.

Dear Marcelo,
as per ur comments it means that there is two HBA and two storage controller/processor. both can see each other. if target means storage controller/processor then in this scenario we have two storage controller/processor, but y it's showing 4targets below is the snap of the same all target have unique serial number. there has to be only 2 targets bcoz we have 2 storage controller /processor.
