| - | ====== Preparing Fedora Core 5 for iSCSI boot ====== | ||
| - | |||
| - | These instructions assume that you have an installation of Fedora Core 5 on a local hard disk. We will make this installation iSCSI-boot-capable, then copy it to a remote iSCSI target and boot from it. | ||
| - | |||
| - | Start by installing the ''gcc'', ''kernel-devel'', ''sysfsutils'', and ''dkms'' packages: | ||
| - | |||
| - | yum install gcc | ||
| - | yum install kernel-devel-`uname -r` | ||
| - | yum install sysfsutils | ||
| - | yum install dkms | ||
| - | |||
| - | You will need to install the iSCSI initiator, the iSCSI Boot Firmware Table utilities, and the iSCSI-capable mkinitrd, which you can find at http://sourceforge.net/project/showfiles.php?group_id=177003&package_id=203976&release_id=447506. Download and install (using ''rpm -Uvh'') the ''dkms-ibft'', ''dkms-iscsi_sfnet'', ''ibft'', ''linux-iscsi'', and ''mkinitrd-iscsi'' RPMs. | ||
| - | |||
| - | If all has gone well, you should now be able to test loading the iSCSI initiator kernel module using | ||
| - | |||
| - | modprobe iscsi_sfnet | ||
| - | |||
| - | You need to mark the network device that you will be using for boot. Edit ''/etc/sysconfig/network-scripts/ifcfg-eth0'' (assuming that ''eth0'' is your boot network device), and append the line | ||
| - | |||
| - | DEVICETYPE=boot | ||
| - | |||
| - | Lastly, you need to rebuild the initrd to include the iSCSI kernel modules, using | ||
| - | |||
| - | /sbin/mkinitrd -f --force-iscsi /boot/initrd-`uname -r`.img `uname -r` | ||
| - | |||
| - | If you use LILO as your bootloader (rather than grub), then you will need to run ''lilo'' after this step. | ||
| - | |||
| - | Reboot and check that the system comes up without difficulties. You will see an error message saying | ||
| - | |||
| - | insmod: error inserting '/lib/ibft.ko': -1 No such device | ||
| - | |||
| - | during the boot process; this is harmless and simply indicates that the system is not actually booting from an iSCSI disk. | ||
| - | |||
| - | You can now proceed to [[iscsiboot#Transferring the operating system image to an iSCSI target]]. | ||
