Make sure the rp_filter setting is set to 0 or 2. If index 5, is free then entry of type bidi chap will be created at that index. This makes it easier to manage them in a server containing multiple interfaces. Before start configuring iSCSI, make sure to have the network interfaces correctly set and configured in order to have open-iscsi package to behave appropriately, specially during boot time. The file content will look something like this: Copied! The 'iscsi-iname' tool can be used to generate a random initiator name that you can later add to the file, but the name already in the configuration file can also be used since it will already be unique. The software was. This will delete any chap entry present at index 5. If a NOP-Out times out, the, iSCSI layer will respond by failing the connection and starting the, replacement_timeout. You need to edit and configure iSCSI via /etc/iscsi/iscsid.conf file; Discover targets. - Manipulate SendTargets DB: Set discovery setting.
