| - | Before clicking on //Next//, press //Ctrl-Alt-F2//. This should take you to a root shell prompt. Configure and start up the iSCSI initiator: | + | |
| - | + | ||
| - | sh-3.2# mkdir /etc/iscsi | + | |
| - | + | ||
| - | sh-3.2# echo InitiatorName=iqn.2007-08.name.dns.my:initiator > \ | + | |

| - | where //name.dns.my// is your DNS name in reverse order. (For completeness, you should also replace //2007-08// with the year and month in which you first obtained your DNS domain. The iSCSI naming schemes are somewhat pedantic, but it won’t affect anything in practice; as long as the initiator name is unique then everything will work just fine.) | + | |
| - | + | ||
| - | Connect to the iSCSI target to be used for installation: | + | |
| - | + | ||
| - | sh-3.2# iscsiadm -m discovery -t sendtargets -p my.iscsi.target:3260 | + | |
| - | + | ||
| - | where //my.iscsi.target// is the DNS name or IP address of your iSCSI target. You will see a list of available target IQNs. Log in to the installation target: | + | |
| - | + | ||
| - | sh-3.2# iscsiadm -m node -T iqn.2007-08.target.iscsi.my:fedora -l | + | |
| - | + | ||
| - | where //iqn.2007-08.target.iscsi.my:fedora// is the IQN of the target that you want to install to. | + | |
| - | + | ||
| - | You are now logged in to the installation iSCSI target. Press //Ctrl-Alt-F6// to return to the graphical installation process, and click on //Next// to proceed to the disk selection screen: | + | |

| - | + | ||
| - | Select and delete the swap partition. This is required for two reasons: firstly, swap over iSCSI (or over any network device) is generally a bad idea; secondly, doing so works around a bug in the Fedora installer which would otherwise result in the partition table never being written to disk. | + | |
