Hi All,

I have this IBM X Series 225 server, LSI SCSI chips(with IM fuction) on
motherboard. I installed two IBM scsi harddisks for Windows 2000 server and
these two disks setup as hardware raid 1 (mirror).

I have questions about scsi mirror setup menu (LSI MPT IM). when I select
one disk as primary, another disk I can set as secondary or hotspare. I
don't any diffrence between secondary and hotspare, whitch one I should use
.. who can explain it to me. because I couldn't find any manual on IBM /LSI
for how to setup it.

Another question is recently Windows system crashed and displayed blue
screen. I checked mirror status, it displayed "Degraded", I also don't know
what is its meaning.

Any help.

Thank you very much

Jeff
