This is the exact correct behaviour, until you added a sudo-command for
/sbin/hpasmcli on your nagios-server! To get this clear: Whenever you
start a command via nrpe, the command defined will be executed on your
_remote_ server. Nagios calls check_nrpe, check_nrpe connects to remote
site and lets the nrpe daemon execute the defined check (check_hpasm).
When you remove check_nrpe from the check_command definition, check
_hpasm is executed _locally_!

No, its bound to the way you configure your nagios. You have to choose
what you want to configure: local check or remote check via nrpe. Make
your choice and concentrate on the solution of just that single problem.
Ok, another try for the nrpe part:
Before checking the real nrpe part, make sure this works:
1. Connect to miysis via ssh.
2. look into /etc/nagios/nrpe.cfg or whereever your nrpe-config is and
get the username nrpe runs under.
3. su - <found_username>
4. sudo /sbin/hpasmcli -help
If this asks you about a password, your sudo-config lacks an entry.
Else, process as follows:
5. Look at the command definition in your nrpe.cfg.
6. Call check_hpasm exactly as it will be called by nrpe.
Only if all that works, and only if all that works, try to check if it
also does from your nagios server by calling check_nrpe.
I would suggest you read over the documentation for nagios and nrpe
again to get the way it works clear.
Oh, and by the way: Gerhard is from southern germany, its impossible for
them to be impatient by any means! ;-)
