SP Switch function (MAP 0620)
Purpose of this MAP
This MAP provides diagnostic information for problems related to the SP Switch function.
Notes:
1. Refer to “Appendix A” in
RS/6000 SP: Installation and Relocation
for frame-to-frame or switch-to-switch
cables. Logical frame to physical frame translation information can also be found in this appendix.
2. Refer to “Service position procedures” on page 3-9 for placing or removing the switch into or from
service position.
Step 0620-001
A message in Perspectives indicated that you have a switch function problem and Table 1-1 on page 1-4
directed you to this MAP.
Note: If out.top does not match the physical switch configuration, run Eannotator. (Refer to
Parallel
System Support Programs for AIX: Installation and Migration Guide
, GA22-7347.
1. To complete the following procedures, you will need to have primary node root access. (Customer may
enter root password when required.)
2. If either of the following two conditions is true:
v
Estart has not been run by the customer
v
The CE has already replaced components that might affect the switch.
then from the control workstation of the “primary” processor node, enter:
Estart
You should receive a message indicating successful initialization at the primary node. If you receive
any other message, consult the “Diagnosing High Performance Switch Problems” section of
IBM
Parallel System Support Programs for AIX: Diagnosis Guide
3. Determine the primary node number. From an AIX
®
window on the control workstation, enter:
Eprimary
4. Determine the host name for this node by checking “reliable_hostname” for the node number with the
command:
