How do I breakdown the Target (tx) part of a cXtXdX Iscsi device?

Hello,

I am trying to breakdown the cXtXdX (specifically tX) part of an iscsi device.

I know in the fibre SAN world, this tX will usually be a combination of the path to device/device WWN.

From what I understand in iscsi world it is similar, breaking down into hba-id/initator-id/Lun-id-or-0.. is this correct?

And if so, how do I seperate these out? How do I knwo which is the hba-id and son on?

Thank you,
