<DIV><SPAN class=994181104-18052005><FONT face=Arial color=#0000ff size=2>Thanks
Bruce, ours says support 4 as well, but we can't get them all running. The
problem turned out to be an Oracle issue, maybe a bug. Let's
explain.</FONT></SPAN></DIV>
<DIV><SPAN class=994181104-18052005><FONT face=Arial color=#0000ff

<DIV><SPAN class=994181104-18052005><FONT face=Arial color=#0000ff size=2>We got
a wrong firewire card, and installed CRS, all 4 nodes run OK. Then I
installed Oracle RDBMS and it failed (due to the wrong hardware). And we
un-installed Oracle RDBMS.</FONT></SPAN></DIV>

<DIV><SPAN class=994181104-18052005><FONT face=Arial color=#0000ff size=2>We
replaced the hardware, and can't get more than 2 nodes running at the same
time. (So I asked the question) Now we found out this is because CSS
daemon repeatedly checking the quorum disk and reboot. We disable the CSS
daemon and all 4 nodes are running happily now.</FONT></SPAN></DIV>

<DIV><SPAN class=994181104-18052005><FONT face=Arial color=#0000ff size=2>Before
I installed Oracle RDBMS, CRS on all 4 nodes were running fine. After I
installed Oracle RDBMS (failed), and CRS started checking quorum disk and
reboot. Don't you think this is an Oracle issue? What triggers
CSS to start checking quorum disk? Why reboot?</FONT></SPAN></DIV>
