Oracle Solaris 9 : Fix "prtdiag -v" failed to excute.

Below  are step to fix out "prtdiag -v" command failed to run when prompting error "Error : picl_initialize failed: Daemon not responding" in Solaris 9

1. Checking the PICLD daemon running or not.
#ps -ef | grep picld

2. If the process not running try to start back the daemon.
#/etc/init.d/picld start

3. If you found the process running as  well, try to restart the daemon as well, Some of time the daemon hanging up.
#/etc/init.d/picld stop
#/etc/init.d/picld start

4. Verify back whether the daemon running or not.
#ps -ef | grep picld

5. Once the daemon are running, try to execute "prtdiag -v" command. Have tried for the several time, seem like the issues fixed after perform the workaround above.
