Answer 1

Talat,
I am having a bit of difficulty understanding your question.
Is it because PRTDIAG uses the work "disabled" ????
If that is the question, then there is no problem.
That component status was discussed in these forums, a long time ago.
http://supportforum.sun.com/hardware/index.php?t=msg&got o=10422
Use the forum search function with keyword <i><u>diskboard</i></u> (all one word).
One of the links in that earlier discussion thread attempts to point to a reference in the SSH.
That link is now available ONLY if you have a Sunsolve login account (with service contract).
<u>This link to another site</u> will provide most of the same SSH info for the diskboard.
