List, I have attempted to make my own megaraid driver disk for a Dell PowerEdge 2300. The procedure I'm using is detailed at the end of this message. In short, I followed samples that I collected after Googling around. The problem I face is that the CentOS 4 installer can't seem to mount the driver disk after I have created it. It gives no information other than, "Cannot mount /dev/fd0", so I don't know where to look to troubleshoot this. If there is a documented procedure for creating good driver disks for CentOS 4, I would very much like to read them; I simply haven't been able to find any, yet. Otherwise, please review the procedure I have detailed in this message to spot the flaw. Thanks!! The procedure I have used to create this driver disk is as follows: ## Log into a machine that is running the 2.6.9-11.EL kernel (e.g.: a working CentOS 4 box). # yum install kernel-devel ## Download the megaraid source from the ALMOST useful (doesn't work because we can't seem to Alt+F2 to get to a bash shell, as described): http://www.tuxyturvy.com/blog/index.php?/archives/4-Installing-RHEL4-on-Systems-with-Legacy-Megaraid-Drivers.html # cd /usr/src # wget http://www.tuxyturvy.com/files/megaraid.tar.bz2 # mkdir /usr/src/megaraid # mkdir /usr/src/megaraid/dd # mkdir /usr/src/megaraid/dd/modules # mkdir /usr/src/megaraid/dd/modules/2.6.9-11.EL # mkdir /usr/src/megaraid/dd/modules/2.6.9-11.ELhugemem # mkdir /usr/src/megaraid/dd/modules/2.6.9-11.ELsmp # cd /usr/src/megaraid # tar jxvfp /usr/src/megaraid.tar.bz2 ## Ignore all warnings. # make -C /lib/modules/2.6.9-11.EL/build SUBDIRS=/usr/src/megaraid modules # cp megaraid.o dd/modules/2.6.9-11.EL/ # rm -f *.o *.ko ## Ignore all warnings. # make -C /lib/modules/2.6.9-11.ELhugemem/build SUBDIRS=/usr/src/megaraid modules # cp megaraid.o dd/modules/2.6.9-11.ELhugemem/ # rm -f *.o *.ko ## Ignore all warnings. # make -C /lib/modules/2.6.9-11.ELsmp/build SUBDIRS=/usr/src/megaraid modules # cp megaraid.o dd/modules/2.6.9-11.ELsmp/ # rm -f *.o *.ko # cd dd/modules/ # find . -type f | cpio -o -H crc | gzip -n9 > ../modules.cgz # cd .. # rm -rf modules/ # echo "LSI MegaRAID driver disk for CentOS 4.0" > centos-4 # vim modinfo ---- add ---- Version 0 megaraid scsi "LSI MegaRAID for Legacy Dell PowerEdge Servers" ------------- # vim pcitable ---- add ---- 0x101e 0x1960 "megaraid" "AMI|MegaRAID (OEM)" 0x101e 0x9010 "megaraid" "AMI|MegaRAID" 0x101e 0x9060 "megaraid" "AMI|MegaRAID" 0x8086 0x1960 "megaraid" "AMI|Megaraid" ------------- # touch modules.dep # chmod 0755 * ## Insert a floppy disk into your floppy disk drive. # fdformat -n /dev/fd0u1440 # mkfs -t ext3 /dev/fd0u1440 # mount /dev/fd0u1440 /media/floppy # rm -rf /media/floppy/* # cp * /media/floppy/ # umount /media/floppy ## Done making the Driver Disk. ## Insert disk 1 of the CentOS 4 install set into your Dell PowerEdge box and reboot the machine. ## At the CentOS 4 install prompt, insert the Driver Disk into the machine and type: > linux dd ## Error: Cannot mount /dev/fd0 ?!
