CentOS - Jul 2008 - Missing SDLT600's

Hi All,
I have a CentOS5.2 server using a Qlogic QLE220 HBA, connected to 
Quantum DX30  and M1800 libraries via a Qlogic SANbox 5600 switch.  I've 
installed the latest (v8.02.14) drivers from Qlogic for the HBA

The issue I have is I am missing 2 of the 4 SDLT drives provided by the 
M1800 Library.  The DX30 provides 6 drives, which are listed in dmesg 
and assigned /dev/st0->5. I would expect the SDLT's to be st6->10 but
I
only see up to st7 and dmesg only lists 2

Using the QLoigic SAN Surfer software all the LUN's/devices are visible 
to the host.

FYI, I also have an old Sun220R connected to this same switch with a 
qlogic card; Solaris 9 has no trouble seeing all LUNs and devices.

I've "googled" for a fair while and have not see anything that
helps. My
FC knowledge on CentOS is limited so any help with troubleshooting this 
would be greatly appreciated.

TIA
Dan

Do you see the devices in /proc/scsi/scsi ?
