Solution
This is a typical failure the communication between daemon picld and system controller.
1) Reset ILOM or ALOM
-> reset -y /SP ( Prompt ILOM )
sc> resetsc -y ( Prompt ALOM )
2) Restart deamon picd on Solaris
For Solaris 10
# /usr/sbin/svcadm restart svc:/system/picl
For Solaris 7, 8 & 9:
# /etc/init.d/picld stop
# /etc/init.d/picld start
3) Check physical System Indicator Status
