Publication Date:  2012-07-18 Views:  62 Downloads:  0
Issue Description
An S5000 storage device maps two LUNs to a host that runs the AIX OS. When the lspv command is executed to view the capacity of the PV that has not been added to a VG, the mapping between a LUN and a PV cannot be distinguished.
