====== Debian etch ====== ===== Preparing an existing installation for iSCSI ===== You can either work with an installation on - a physical disk on a client machine or - a ''chroot(8)'' environment operating on a loopback-mounted disk image Install the ''open-iscsi'' package. apt-get install open-iscsi Since two fundamental tools from open-iscsi are not included in the debian package, they have to be compiled from the sources with the following steps (i have used a different machine for all the compilation stuff). Install the appropriate devel packages: apt-get build-dep open-iscsi apt-get install libdb4.3-dev Download the sources and compile them: wget http://www.open-iscsi.org/bits/open-iscsi-2.0-865.13.tar.gz (this is the latest tarball at this time) tar xzf open-iscsi-2.0-865.13.tar.gz cd open-iscsi-2.0-865.13 make -C usr make -C utils/fwparam_ibft The two files needed are ''usr/iscsistart'' and ''utils/fwparam_ibft/fwparam_ibft'' so they have to be copied in ''/usr/sbin''. Create two scripts shown below. These scripts have to be executable. * ''/etc/initramfs-tools/hooks/iscsi_tcp'' will copy the ''iscsi_tcp'', ''iscsi_iser'' kernel modules followed by their dependancies, ''/usr/sbin/iscsistart'' and ''/usr/sbin/fwparam_ibft'' to the initial ramdisk. * ''/etc/initramfs-tools/scripts/local-top/iscsi_tcp'' is copied to the ram disk and run at boot-time, just before the root filesystem is mounted. If the root device string looks like a SCSI device it brings up the appropriate Ethernet device, sets up the ip address passed through dhcp and connects the root file system on the iSCSI target.
