Context : 6H1 AIX5.1 and HACMP4.4.1


I encoutered a new pb last friday evening :

After a mere reboot (but are there any mere reboots) my 6H1 refuses to
launch the hacmp processes, though the "start on restart" command had
been submitted

See the tail of /etc/inittab

hacmp6000:2:wait:/usr//sbin/cluster/etc/rc.cluster -boot -i -b #
Bring up Cluster

<<<<

The system restarted, but no cluster processes appeared though I wait
for more than 5 mn. (nothing visible with the lssrc -g cluster
command)
I finally typed the smitty clstart now command and it immediatly
started and brought the resources on.

What could have happened, dear gurues ?

I answer my own message, due to a discussion with a colleague.
He says that, though commented lines (beginning with a : character)
are supported in the inittab, these comments must be at the beginning.

Does anybody confirm ?

To make a long story short : is it safe to insert comments in the
inittab file ?

It is safe to insert comments into inittab, they can be anywhere in
the file, but they must have a : as the first character. It is also
supported to have a comment at the end of an entry, preced by a #
(hash) e.g. dsmcad:2nce:/usr/tivoli/tsm/client/ba/bin/dsmcad
>/dev/null 2>&1 # Start TSM W
eb Agent

Lines begging with a : are acceptable comments in /etc/inittab
throughout the file. I use this technique frequently when commenting
out lines that I do not want executed while I am testing.

Hope this helps.

Thanks to both of you.

By the way, some says empty lines (CR alone) could make PB in inittab.
Do you confirm ?

I've never seen a blank line in inittab, so couldn't comment. The
recommended way to update inittab is to use mkitab and rmitab and this
doesn't (AFAIK) allow you to put a blank line in.
