ask | dr. root

(I've tried to summarise the information I was emailed into the one-line question above)

You were trying to locate the scadm utility, It could be in /usr/platform/platform-name/sbin/

To get the path from your system, type:

# /usr/platform/`uname -i`/sbin/

To assign a new password to admin with the scadm utility, you will first need to log in to the system as root, and then use the command:

# scadm userpassword admin

The system won't ask you to enter the existing password.

In the case of the Sun Fire V890 -- and Sun Fire V480 and Sun Enterprise 250 -- you can also administer the system from a Sun Remote System Control (RSC) console, IF the latter has been installed and explicitely enabled on the system.

If it's enabled on your system, and if you're happy to use RSC, there's an rscadm utility, with a number of sub-commands, that allows you to administer the Sun Remote System Control from the host. To use rscadm, again just log in to the server as root.

Note: By default, installation places the rscadm utility in the directory /usr/platform/platform-name/rsc/

To get the path from your system, type:

# /usr/platform/`uname -i`/rsc/

As you've no idea what the password is, just simply log in to the Sun Fire V890 as root and use the command:

# rscadm userpassword admin

It will assign a new password to the admin user of the RSC console, without prompting you for the existing password.

That should be it...

Don't forget to check the documentation for full details!
