You must have dual HBAs ( 2 fibre channel cards connected to the MSA1000. If you don't have multipathing software like Secure Path for Linux or the QLogic multipathing software that comes with the QLogic HBA -- or can be downloaded from the QLogic website -- you will see both paths to the luns. 2 HBAs x 7 luns = 14. Multipathing software hides one of the paths for the OS.
