[Q] SRC/P intelligent RAID control card?

[L]

We have SUN E450 witn Solaris 2.7 installed.  The computer have three 
backplanes.  first and second backplane use regular SCSI control card and
third backplane(top) use SRC/P intelligent control card.  Currently, there
have 9 internal HD(id 0-8).  I installed the intelligent RAID software and
run "dptmgr", their has icon "hba0" display and NO hard disk associate to it.
I call SUN support engineer, he told me SRC/P can only work with HD 
connect to it(it mean each backplane need SRC/P control card).  I saw the
document mention SRC/P can control 16 internal
HD and 36 external HD.  If it is true, why SRC/P can NOT find another
backplane HD?


Can anyone confirm that?


Thanks.
