Mylex RAID Controller 400/500 1

[sittnduck]

I am building two dual cpu Linux systems, I have the Mylex 400/500 RAID controller, Tyan S2720 motherboard (without onboard SCSI) and 4 73.6 Quantum ATLAS 10K II drives. The drives are 80 pin SCA, so I bought adapters from scsi4me.com to convert to 68 pin. When booting I can get into the BIOS of the RAID controller by hitting the alt-m and I can configure the BIOS, but, when trying to load the controller configuration with the alt-r as indicated, I get no response except for a brief message stating it will initiate the configuation after the system posts. There is also a message stating that "No system drives installed". That makes sense because I can not get to the controller config to setup system drives. I have correct ID's on each adapter, these drives have no jumper settings but to disable or enable SE/LVD, so all settings have to be configured on the 80 to 68 pin converters. Try as I might, I can't get to the controller config, so I am not sure it is picking up the drives, although it does indicate "spinning up drives", Any idea's or suggestions from some SCSI guru's would be helpful.

Thanks

Mylex normally supplied a utility diskette with the controller that would allow you to get into and configure the drives. The DACCF utility has worked for me in the past when ALT- R would not work. Just need a bootable diskette with that utility on it. Give me an email if you need the util.

That works great! Thanks for the tip. I just noticed clustering is not supported on this controller. Does anyone have any recommendations on the best way to load balance using redhat and two dual cpu servers? The sql database is already on another box. This site gets about 7 million hits a month and I am wanting to offload the web services and other misc to two seperate paths, based on alphabetical user login.
