4.1.2. Discovery and Login
i. Starting iSCSI Daemon
Start Daemon from /sbin by using the following command:
[root@host~]# iscsid -f -d 3
ii. Discovering iSCSI Targets
To discovery an iSCSI target execute a command in the following format:
iscsiadm -m discovery -t st -p <target ip address>:<target port no> -I
<cxgb4i iface file name>
E.g.:-
[root@host~]# iscsiadm -m discovery -t st -p 102.2.2.155:3260 -I
cxgb4i.00:07:43:04:5b:da
iii. Logging into an iSCSI Target
Log into an iSCSI target using the following format:
iscsiadm -m node -T <iqn name of target> -p <target ip address>:<target port
no> -I <cxgb4i iface file name> -l
E.g.:-
[root@host~]# iscsiadm -m node -T iqn.2004-05.com.chelsio.target1 -p
102.2.2.155:3260,1 -I cxgb4i.00:07:43:04:5b:da -l
If
iscsid
is already running, then kill the service and start it as shown above
after installing the Chelsio Unified Wire package.
Note
i. The interface file needs to be created in /etc/iscsi/iscsid.conf .
ii. If
iface.ipaddress
is specified, it needs to be either the same as the
ethX's IP address or an address on the same subnet. Make sure the IP
address is unique in the network.
