What you need for this ancient machine and RAID controller is arcconf version 9.30. It is quite hard to come by these days. Ideally, you'd want ibm_sw_srapp_9.30-17006_anyos_32-64.iso, which also includes RaidMan, but this download has been removed. Try this one: ftp://download2.boulder.ibm.com/ecc/sar/CMA/XSA/ibm_utl_aacraid_arcconf-9.30-17006_linux_i386.zip
