The errors I am seeing on the terminal on boot up are:
0509-036 Cannot load program /usr/sbin/sshd because of the following errors:
0509-150 Dependent module libz.a(libz.so.1) could not be loaded
0509-022 Cannot load module libz.a(libz.so.1)
0509-026 System error: A file or directory in the path name does not exist.

any ideas?

Let's get some terminology straight before we go on. You're not locked out of the hmc, you've got an AIX instance you can't connect to, either remotely via ssh (did you try telnet?) or using the virtual console provided by the hmc?

The errors your seeing can be caused by permissions being changed on the host preventing necessary files being accessible.

The first question I would ask if I was you, is when did this start, and the second question is, what change was must just prior to when it started.

It could be many things (disk corruption, permission issues, someone's attacked your server, etc.)

Can you boot into maintenance mode using a CD or NIM?

Thanks Tony.

I was able to get in via maintenance mode using a CD. What I found was that bash (root's shell) was on a mount that wasn't being mounted at startup.

Neither /opt (or bash) are new to this machine.

/opt:
dev = /dev/hd10opt
vfs = jfs2
log = /dev/hd8
mount = true
check = true
vol = /opt
free = false
In maintenance mode I changed the shell to ksh. fsck on /opt went through without any errors.

When logged into the system I can do a mount -a and /opt gets mounted correctly.

Any ideas on why /opt isn't being mounted at startup?

Thanks again,
Adam

Attached is the complete alog output.

What I will probably end up doing a complete reinstall unless you are able to see the problem from the log file.

Thanks again for the help.
