This book applies to PSSP Version 3 Release 4. To find out what version of PSSP is running on your control workstation (node 0), enter the following:

splst_versions -t -n0

In response, the system displays something similar to:

0 PSSP-3.4

If the response indicates PSSP-3.4, this book applies to the version of PSSP that is running on your system.

To find out what version of PSSP is running on the nodes of your system, enter the following from your control workstation:

splst_versions -t -G

In response, the system displays something similar to:

1 PSSP-3.4
2 PSSP-3.2
7 PSSP-3.1.1
8 PSSP-2.4

If the response for a particular node indicates PSSP-3.4, this book applies to the version of PSSP that is running on that node.

If you are running mixed levels of PSSP, be sure to maintain and refer to the appropriate documentation for whatever versions of PSSP you are running.
