My apologies. I should have put more context around my question. I was trying to keep my post concise and to the point. Given your lengthy response, I will respond in kind. I am not sure where you got the idea that I am trying to cram and fake my way but I can assure you, that is absolutely not the case. My background is in Directory Servers and IAM products. My last position was administering Ubuntu and Centos systems. My entire career has been spent working in Unix environments of all flavors mostly from an application engineering perspective. The position I am interviewing for was presented to my by a recruiter, as many are, who found my resume online. There is nothing in my resume that mentions anything about administering AIX other than from working with applications on AIX systems. When contacted by the recruiter, I presented him with the facts and told him up front that I had never performed AIX administration and that my only unix admin experience was with Ubuntu and Centos systems. I was very up front with him and gave him several references who could attest to my background and work ethic. I can assure you that I am not trying to present myself as an experienced AIX admin. I am well aware of the fact that this is an impossibility. My goal is to do my research and present myself as being, at least somewhat, intelligent of the task at hand. You do mention presenting oneself with integrity which I absolutely agree with 100%. I am going into this interview with base knowledge, a strong work ethic and a desire to learn. Again, my only goal with doing research is to be able to present myself with some aspect of base intellect at the position.
To reiterate my question which really wasnt answered
is PowerHA applicable on all newer AIX systems as a tool for setting up high availability and failover or is PowerHA specific to Power systems.
I am well that this is most likely a stupid question to the firmly entrenched and highly knowledgeable but I am a firm believer of the old axiom "there are no stupid questions"
I should also mention that I do not know what systems the position will be working with which is why I am asking the question in the first place

cgi-fcgi
NAME
cgi-fcgi - bridge from CGI to FastCGI
SYNOPSIS
cgi-fcgi -f cmdPath
cgi-fcgi -bind -connect connName
cgi-fcgi -start -connect connName appPath [nServers]
cgi-fcgi -connect connName appPath [nServers]
DESCRIPTION
cgi-fcgi is a CGI/1.1 program that communicates with an
already-running FastCGI application in order to respond to
an
HTTP request. cgi-fcgi is also capable of starting a FastC-
GI
application.
When you invoke cgi-fcgi as
cgi-fcgi -f cmdPath
then cgi-fcgi opens the file at cmdPath and reads its
arguments from that file. cgi-fcgi will skip lines
that begin with the comment character #. The first
non-comment line should contain valid arguments in
one of the other three forms.
The -f form of cgi-fcgi is designed for Unix systems
whose exec(2) family of system calls supports the execution
of
command interpreter files. For instance, if a file with
execute permission contains the text
#! /bin/cgi-fcgi -f
-connect /httpd/root/sock/app /httpd/root/bin/app
the effect is the same as executing
/bin/cgi-fcgi -connect /httpd/root/sock/app
/httpd/root/bin/app
When you invoke cgi-fcgi as
cgi-fcgi -bind -connect connName
the connName argument is either the path name of a Unix do-
main
listening socket or a host:port pair. If connName contains
a colon, it is assumed to be host:port. cgi-fcgi performs
a connect(2) using connName. If the connect succeeds, cgi-
fcgi
forwards the CGI environment variables and stdin data to the
FastCGI application, and forwards the stdout and stderr data
from
the application to cgi-fcgi's stdout (most likely connected
to
a Web server). When the FastCGI application signals the end
of
its response, cgi-fcgi flushes its buffers and
exits, and the Web server completes the http response.
When you invoke cgi-fcgi as
cgi-fcgi -start -connect connName appPath [nServers]
then cgi-fcgi performs the function of starting one or more
FastCGI application processes. The connName argument speci-
fies
either the path name of the Unix domain listening socket
that
cgi-fcgi will create, or is "localhost:NNN" where NNN is the
port
number of the TCP/IP listening socket that cgi-fcgi will
create
on the local machine. (cgi-fcgi will not create processes
on remote machines.) After cgi-fcgi creates the listening
socket,
it forks nServers copies of a process running the executable
file
appPath. If nServers is omitted, the effect is as if the
value "1"
had been specified. The processes share the single listen-
ing socket.
When you invoke cgi-fcgi as
cgi-fcgi -connect connName appPath [nServers]
cgi-fcgi performs -bind and then, if necssary, performs
-start
and repeats the -bind. That is, cgi-fcgi first operates as
if
the command had been
cgi-fcgi -bind -connect connName
If the connect fails, cgi-fcgi tries
cgi-fcgi -start -connect connName appPath [nServers]
and finally retries
cgi-fcgi -bind -connect connName
In this form, cgi-fcgi does not support TCP/IP connections.
ENVIRONMENT VARIABLES
The usual CGI ones, but they are not interpreted by cgi-fc-
gi.
SEE ALSO
FGCI_accept(3)
BUGS
cgi-fcgi doesn't generate useful HTTP responses in case of
error,
and it generates no response at all when run as start-fcgi.
On Digital UNIX 3.0 systems the implementation of Unix Do-
main
sockets does not work when such sockets are stored on NFS
file
systems. Symptom: cgi-fcgi may core dump or may exit with
status 38. Work-around: store sockets in local file systems
(/tmp often works) or use TCP/IP.
On AIX systems the implementation of listening sockets
does not support socket sharing, and the standard FastCGI
application libraries can't synchronize access to AIX lis-
tening
sockets. Work-around: Don't use the nServers argument on
AIX.
