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 ?
Actually, no. Below is the output from /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.
