the evaluators and configuration files on Windows; /UNIX_Linux for the evaluators
and configuration files on UNIX platforms; and /licenses for the license files.

Target system
Windows
UNIX
Prerequisites
The Telnet client is enabled, so that the
connectivity checks in the predefined
Connectivity collector can function correctly.
v Bash is installed, so that the Prerequisite
Scanner UNIX collectors can function
correctly.
v For non-root users, the location of the
mount, swapinfo , and psrinfo commands
must be set in the PATH environment
variable, so that the commands are
available to Prerequisite Scanner. The
commands are in the /usr/sbin directory;
for example, set the PATH environment
variable as follows:
export PATH=$PATH:/usr/sbin/
v Ensure the correct access permissions are
assigned to the lscfg command, including
any specific permissions that are set by
the access-right flags such as setuid bit.
The correct access permissions mean that
Prerequisite Scanner can run the
command and retrieve system
information. The command is in the
/usr/sbin directory; for example to set the
setuid bit for lscfg, run chmod command
as follows:
chmod 4777 /usr/sbin/lscfg
