So if HACMP changes the level from 2 to a is it OK to change it back to 2 ?[...]
rctcpip:a:wait:/etc/rc.tcpip > /dev/console 2>&1 # Start TCP/IP daemons
I would not recommend that.... The reason for this change of the startup procedure is that HACMP does not know whether an IP address that is necessary for operation is available after reboot. It would be possible to start the cluster with addresses that are used for heartbeat only and without a proper network connection the daemons might fail or at least fill your logs with all sorts of errors. So what you could do is make sure that the cluster nodes have a suitable active and routeable IP even while HACMP is not started e.g. as a persistant address. Then you can either start daemons separately from inittab or (if there are too many daemons you need) from a separate rc file which again could be called from inittab at runlevel 2. You should not however change the rc.tcpip as trying to start a daemon twice does not result in problems usually while it might turn out to be a problem if the clusters misses a daemon it expects to have started itself. You must not change an inittab entry from runlevel a back to runlevel 2. That would be very bad administration practice (and btw might be reversed by the cluster occasionally without giving notice).

mailstats
MAILSTATS(8) System Manager's Manual MAILSTATS(8)
NAME
mailstats - display mail statistics
SYNOPSIS
mailstats [-c] [-o] [-p] [-P] [-C cffile] [-f stfile]
DESCRIPTION
The mailstats utility displays the current mail statistics.
First, the time at which statistics started being kept is displayed, in the format specified by ctime(3). Then, the statistics for each
mailer are displayed on a single line, each with the following white space separated fields:
M The mailer number.
msgsfr Number of messages from the mailer.
bytes_from Kbytes from the mailer.
msgsto Number of messages to the mailer.
bytes_to Kbytes to the mailer.
msgsrej Number of messages rejected.
msgsdis Number of messages discarded.
msgsqur Number of messages quarantined.
Mailer The name of the mailer.
After this display, a line totaling the values for all of the mailers is displayed (preceded with a ``T''), separated from the previous
information by a line containing only equals (``='') characters. Another line preceded with a ``C'' lists the number of TCP connections.
The options are as follows:
-C Read the specified file instead of the default sendmail configuration file.
-c Try to use submit.cf instead of the default sendmail configuration file.
-f Read the specified statistics file instead of the statistics file specified in the sendmail configuration file.
-P Output information in program-readable mode without clearing statistics.
-p Output information in program-readable mode and clear statistics.
-o Don't display the name of the mailer in the output.
The mailstats utility exits 0 on success, and >0 if an error occurs.
FILES
/etc/mail/sendmail.cf The default sendmail configuration file.
/var/lib/sendmail/statistics
The default sendmail statistics file.
/etc/mail/statistics The symbolic link to the statistics file.
