Adding an SP expansion I/O unit to an existing node

Perform the following steps to add an SP expansion I/O unit to an existing node.

Step 1: Archive the SDR

Before adding an SP expansion I/O unit to an existing node, you should back up the SDR by issuing:

SDRArchive

Note the location and the name of the file created after you issue this command.

Step 2: Shut down the node and power it off

Prior to shutting down the node that you are adding the SP expansion I/O unit to, make a list of all the applications and programs running on the node (such as LoadLeveler) and stop them from running.

Use Perspectives or the cshutdown command to shut down the nodes. For example, issue:

cshutdown -G -N 45

Step 3: Install, cable, and power on the new SP expansion I/O unit

Your IBM Customer Engineer (CE) performs this step. See RS/6000 SP: Installation and Relocation for instructions.

Step 4: Power on the node

Power on the node using the cstartup command. For example:

cstartup -G -N 45

Step 5: Verify the SP expansion I/O unit configuration

To verify that the SP expansion I/O unit is properly configured in the SDR, issue:

splstdata -x
