From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Description of problem: Qlogic 2200 driver is loop only, and does not work with fabric switches. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Setup Qlogic 2200 to enable BIOS for boot to SAN 2. Run fibre cables through a fabric switch 3. Attempt to load Advanced Server to LUN 0 on SAN Actual Results: Advanced Server fails to see a LUN to install to Expected Results: Advanced Server should have installed to LUN 0 on SAN Additional info: This procedures works fine with RedHat 7.2. The QL2x00 driver that is included with RedHat 7.2 will login to the switch as an FL port. RedHat 7.2 can be installed to LUN 0 on the SAN with no problem. However, the QL2200 driver included with Advanced Server trys to login to the switch as an L port. Therefore, Advanced Server cannot be installed to LUN 0 on a SAN.
There is a bug in the current driver that is almost certainly the cause of this. The fixed driver is available in an Advanced Server kernel errata: http://rhn.redhat.com/errata/RHSA-2002-128.html Unfortunately, this errata will not help you to do an installation with the current AS CDs. To address that, I will need to give you a Device Driver Update Disk. There may be a simpler workaround, though, if you are willing to try it. There is a topology parameter that you can set to "fabric" in the qLogic BIOS utility, as follows: Press ALT-Q during self test. Under "Configuration settings", "Extended Firmware settings", "Connection Options" there are 4 choices. Set it to "Fabric only". Then try the install. Let me know if this works. I will send you a driver update disk if you need it, just let me know.
