IBM RS/6000 SP 1-28

dsh -a /usr/lpp/ssp/css/rc.switch

Note: When working with a two-plane SP Switch2 system, add the adapter name to the command, as

follows: dsh -a /usr/lpp/ssp/css/rc.switch -a

<adapter_name>

Example:

dsh -w fr2n03,fr2n04,fr3n01 /usr/lpp/ssp/css/rc.switch

Attention: Issuing this command on processor nodes that did

not

lose a connection may cause

unpredictable results.

3. Have customer start the switch code from the control workstation by entering:

Estart

4. Check /var/adm/SPlogs/css0/p0/out.top file on the primary node.

5. Go to “Step 0620-001” on page1-17 to verify that there are no other switch problems.
