I have a bunch of servers that cant connect via rsc, but supposingly they can connect...
Any chance I can check if the rsc card is physically exist in the server by some command? Some of the machines are in overseas, and I won't go datacenter to check anyways...
Many Thanks!
prtdiag -v will show you if the RSC card exists
Thanks incredible 
I got below result from prtdiag -v, seems doesnt shows rsc card details but confirmed this machine has rsc installed...any thoughts? Many thanks again...
bash-2.05$ prtdiag -v

Indeed prtdiag isn't the right tool for that.
You can first check if the SUNWrsc package is there. If it isn't there, the RCS board is unlikely to be there too.
If SUNWrsc is installed, run (ksh):
# /usr/platform/$(uname -i)/rsc/rscadm show
That should show the RSC configuration or an error message if that board is missing.
The RSC package can be installed even though there might not be any RSC card there physically..
So you're trying to use the "show" option here to see if it yields any output?
As I wrote, there will always be an output, whether regular or an error message.
You can look to see if the /dev entry exists:
root# ls -l /dev/rsc-control
lrwxrwxrwx 1 root root 58 Aug 10 2006 /dev/rsc-control -> ../devices/pci@9,700000/ebus@1/rsc-control@1,3062f8:sspctl
You can also look at prtconf -vP and look for lines like these:
rsc-control, instance \#0
