2. Put the SP Switch’s circuit breaker into the On (‘1’) position.

Step 0620-043
You have replaced switch components and need to verify that the problem has been fixed.
1. Make sure any processor node(s) that was put in SERVICE mode is returned to NORMAL mode.
Make sure all processor node(s) are IPLed completely in NORMAL mode.
2. If any processor nodes that lost switch clocks before or during service (due to unplugging node
data/clock cable, loss of clock at the SP Switch connected to processor nodes, or so on), you will need
to include them in the following command. From the control workstation, enter:
dsh -w
nodelist
/usr/lpp/ssp/css/css_restart_node
OR, if all processor nodes have lost switch clocks, enter:
dsh -a /usr/lpp/ssp/css/css_restart_node
where
nodelist
is a list of node names separated by commas.
Example:
dsh -w fr2n03,fr2n04,fr3n01 /usr/lpp/ssp/css/css_restart_node
Attention: Issuing this command on processor nodes that did
not
lose a clock may cause
unpredictable results, possibly requiring reIPL.
3. Have customer verify that the switch code is running on all processor nodes OR from the control
workstation, enter:
Estart
4. Check /var/adm/SPlogs/css/out.top file.
5. Go to “Step 0620-001” on page 1-17 to verify that there are no other switch problems.
