what is paths when we expand the HBA under storage adapter.Actually there are only two HBA adapter but there are 12 paths

What actually does it means

[a_p_]

The paths are "ways" over which a single HBA can access a given LUN. In your case the HBA is able to see each LUN over two paths, one to each storage HBA ("T0" and "T1").

1 ) What is target in the picture

2) what is active and active (i/o)

Target is a SCSI term for (simplified) a device which can provide access to a volume.  If you have an array that has multiple independent 'controllers' (sometimes called heads, nodes, SPs, directors, etc), you will have at least 2 targets (sometimes more, depending on design).

'Active' indicates that the path is ready for IO to be sent down it, but isn't currently being used.  'Active (IO)' indicates this path is active and IO will be sent that direction.   The 'IO' designation may change over time.
