There are however, some commands that dont work via rsh. I dont have a list handy, but they do exist.

Nope! Just have to have the root access - you can use rsh to do any command from a remote machine. You can't do a straight rsh to get a shell on a filer, but you can do rsh <filer> <command> as root on a box that has root permissions to the filer...
I just discovered it the other day....

If all you wish to do is halt it...type halt.
You can telnet to it, rsh to it, use Filerview...
I would imagine all of these need a password to log in, which the user doesn't have.... Right?

Hi,
Please, forgive me if this is in some FAQ but I couldn't find any. (Could you point me to it?)
I've lost the root password of our filer. I've read in the SA Guide that I can change it by booting from a diskete. However, the filer is up and running. How can I reboot it in a safe manner having no access to its command line (short of powering it down)?
**THIS IS TOTALLY UNTESTED**
I would think if you failed a drive, the system would bring itself down cleanly after X hours.

however many that won't normally run via rsh will run if you rc_toggle_basic first.

And there's often a very good reason why not. Using this to "get around" non-rshable command limitations can compromise your filer and lead to many crashes.

it can and has often saved me from having to track down who is telnetted in when for some reason the console port is unavailable. also on my older filers our operators telnet in to kick off backups. if for some reason i need to run commands on the filer this is the only way.
i haven't yet had a filer crash due to running commands via rsh. knowing that this option is available is useful, but as with any operation on the filer, sure, it has the potential to crash the machine.

These are all administrative issues, however. The backups could be run by rsh or other means. You could also run only the rsh-safe commands on the filer.

It has a greater potential to crash the machine because there's a reason those commands aren't rsh-able.
It's possible in a future release that running those non-rshable commands through rsh via rc_toggle_basic will cause a crash every time, or it will report false data which then results in your doing the wrong thing. If you are aware of these risks and will only blame yourself, fine, but I would not want to risk it if it can be avoided.
