Hello, I'm trying to install CentOS 6.0 64bit on a HP ProLiant ML110 G7 with a HP Smart Array B110i SATA RAID Controller. One logical drive (RAID 1+0) on the RAID Controller is already build. CentOS Installation can't find the logical Drive, but it shows me the zwo physical drives (sda+sdb). After searching the web, I found following hints: http://www.linuxquestions.org/questions/linux-hardware-18/raid-array-not-detected-new-hp-ml150g6-server-739130/ http://linuximagination.blogspot.com/2011/04/centos-installer-wasnt-detecting-sata.html OK. Downloaded the file "hpahcisr-1.2.6-7.rhel5.x86_64.dd.gz" and do the dd from another Linux workstation. # dd if=hpahcisr-1.2.6-7.rhel5.x86_64.dd.gz of=/dev/sdb (4Gig USB Stick) starting the CentOS 6.0 64 bit installation from the DVD boot: linux dd After loading the kernel, the installer is asking whether I have driverdisk and asked to indicate which drive (sdc) /dev/sdc is my 4Gig USB Stick. My problem is now, the step "Driver Disk" is failed: Failed to mount driver disk. any hints are very, very welcome. Thanks in advance Richard
