After a cold restart or after powering on the system, the RSC command rscadm resetrsc fails; this is a known condition. You need to reset the host system for the command to function correctly.
There are three ways you can reset the host. Use one of the following commands:
At the ok prompt, execute the reset-all command.
At the RSC command-line interface (CLI) prompt, issue the reset command.
At the Solaris CLI prompt, issue the reboot command.
The RSC rscadm resetrsc command will now function correctly.
