Reset RSC thru Solaris

We have to patch a Sun V480 and during the pre-tasks we have to check on the console of the box. To our surprise (or not) the console is hung. We have to reset the Remote System Console (RSC) for to be able to use it again. Here are the simple guide on how to reset the RSC thru the OS.

Try to check if the RSC is still responding:

root@solaris# /usr/platform/`uname -i`/rsc/rscadm shownetwork
rscadm: RSC firmware not responding~

To perform soft reset:

root@solaris# /usr/platform/`uname -i`/rsc/rscadm resetrsc -s
Are you sure you want to reboot RSC (y/n)? y
rscadm: RSC firmware not responding

If it still not help, perform a hard reset on the RSC:

root@solaris# /usr/platform/`uname -i`/rsc/rscadm resetrsc
Are you sure you want to reboot RSC (y/n)? y

Now you should be able to log-in to your RSC.
