Attach the hardware.

Set up the storage system so that its LUs are accessible via the cable, and then connect the cable

to the iSCSI target has been specified. Refer to storage systems User's Guide -Server Connection- or any

other relevant manuals and "Appendix 2" in the software information (/opt/FJSVmpd/manual/english/

Use the "iompadm info" command to check that the new cable has been correctly

recognized and incorporated.
