Path Addition (Cable Addition)
This section describes how to increase the paths by adding cables.
Using the "mpdconfig" command, cables can be added. Use the following procedure.
Procedure
1
Attach the hardware.
Set up the storage system so that its LUs are accessible via the cable, and then connect the cable
between the server and the storage system (a NIC must already be installed in the server). For details
on the settings, refer to the storage system manual.
2
Set the server iSCSI service.
Set iSCSI initiator/iSCSI target information and log in to the iSCSI target. Make sure that automatic login
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/
readme.pdf) for details about iSCSI connection.
3
Use the "iompadm info" command to check that the new cable has been correctly
recognized and incorporated.
[Example]
4
Set a Max Throttle value for the new path.
Execute the "mpdconfig -m" command to set a Max Throttle value for the new path. Refer to the
software information (/opt/FJSVmpd/manual/english/readme.pdf) for the Max Throttle value
computation method.
