13.2.4 Configuring Online Targets with ietadm

When changes to the iSCSI target configuration are necessary, you must always restart the target to
activate changes that are done in the configuration file. Unfortunately, all active sessions are
interrupted in this process. To maintain an undisturbed operation, the changes should be done in the
main configuration file
/etc/ietd.conf
the administration utility ietadm.
To create a new iSCSI target with a LUN, first update your configuration file. The additional entry
could be:
Target iqn.2006-02.com.example.iserv:system2
Lun 0 Path=/dev/mapper/system-swap2
IncomingUser joe secret
To set up this configuration manually, proceed as follows:
1 Create a new target with the command
Name=iqn.2006-02.com.example.iserv:system2
2 Add a logical unit with
mapper/system-swap2
3 Set the username and password combination on this target with
-user --params=IncomingUser=joe,Password=secret
4 Check the configuration with
It is also possible to delete active connections. First, check all active connections with the command
