Each LUN is seen twice but the multipathing hides it so we only see one device for each LUN. > You have (presumably) set up the LUNs as raw devices (ie not > block) to > allow ASM to interact correctly with them - correct? No. I partitionied the LUNs as type Linux, so /dev/sdc became /dev/sdc1 when presented to the box for ASM. I did not put a filesystem on the LUNs however. I originally did not partition them but the DBA's told me ASM would not accept them when they tried to add them in. > You've set the "Host type" of the RX boxes to be "Linux" from within > Command View - correct?

These machines already have LUN's attached for other filesystems not in ASM, eg /opt/oracle, /opt/Tivoli etc. When ASM fails the rest of the filesystems are fine. Cheers, Nick .
