Unable to run root scripts' error message is displayed on computers running Red Hat Enterprise Linux AS 3.0

The installation utility displays an Unable to run root scripts error message at the end of a product installation and in the product log file on computers running Red Hat Enterprise Linux AS 3.0 for IBM zSeries, even though the installation was successful.

To fix the problem

Perform one of the following tasks:

• Run the root scripts manually after the product installation is complete. The installation utility creates a root script log that lists the scripts that were to be run during the installation session and each script's arguments. You can use this log file to determine what scripts you will need to run. By default, the script log file is located in a subdirectory in the $HOME/BMCINSTALL directory and uses the following naming convention: computername_timestamp.log_rootscripts.
• Create a pseudo terminal as follows before you install products in this environment:
  1. Log on as root.
  2. Enter the following commands:
      mknod /dev/ttyp0 c 3 0
      chmod 666 /dev/ttyp0
      You need to create only one device for Expect to work correctly. Expect will try to open /dev/ttyp0 and if it's unsuccessful, will try the next device through the character set 0123456789abcdef.
