Addition without Server Rebooting

Extra storage systems can be added without shutting down the server. Use the following procedure.
Procedure
1
Attach the hardware.
Set up the storage system so that its LUs are accessible to the server, and then connect it to the server.
For details on the settings, refer to the storage system manual.
2
Use the "iompadm info" command to check the result.
When the new storage system is connected to the server, it should be automatically recognized and
incorporated in the list.
[Example]
# /opt/FJSVmpd/bin/iompadm info
3
Set its Max Throttle value.
Execute the "mpdconfig -m" command to set a Max Throttle value for the new storage system. Refer to
the software information (/opt/FJSVmpd/manual/english/readme.pdf) for the Max Throttle value
computation method.
[Example]
# /opt/FJSVmpd/bin/mpdconfig -m

If by-id names are not being used, or are being used with FUJITSU Software PRIMECLUSTER
