Getting it to work was a headache, mostly for firmware problems. The firmware of the DEC oem controllers was not updated as frequently as the one on PC's, as a matter of fact, i could never get the upgrade programm (ARC based) to work. I would=20 a) Check that the firmware is the latest supported revision for the controller. The upgrade needs to be done on a PC. 2.73-0-00 is the minimun for FreeBSD. 3.X is much better, i.e it allows to use the mlxtools, but you need a controller with two EEPROMS to be able to install it!=20 b) Check that the Dallas NVRAM is OK, if the controller has been sitting idle for a long time, i would replace it just for good measure c) Erase all the array config and rebuild from scratch using the latest utilities ON THE ALPHA!. What is the actual config on your machine (Firmware revision, Disk make and size, Raid config, strip size) Get me some more info and i'll try to provide a detailed procedure for you.
