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 ?

You can try rescanning the bus:

But it sounds like despite what the qlogic app says the devices
are not exported to the host.

Thanks Nate, I've tried that solution and a whole bunch of other tools
from Qlogic, still no joy. The thing that confuses me is the drives are
viable to my Solaris host. I'll give Quantum a ring and see if there is
anything needed on the M1800 to remedy this.
