Datera

Once iscsiadm has been used, the iSCSI Qualified Name (IQN) can be found in /etc/iscsi/

When authentication is not enabled, it's easy to access provisioned storage, where the ip is taken from the Datera GUI:

iscsiadm -m discovery -t st -p ip:port

Logging in:

iscsiadm --m node -T iqn.2007-06.com.test.cluster1:storage.cluster1 --portal 172.16.48.175:3260 -l

Disabling a target:

There are three ways to disable or delete an iSCSI target.

First, to disable an iSCSI target:

iscsiadm --m node -T iqn.2007-06.com.test.cluster1:storage.cluster1 --portal 172.16.48.175:3260 -u

Second, it is possible to delete the target's record ID:/p>

iscsiadm -m node -o delete -T iqn.2007-06.com.test.cluster1:storage.cluster1 --portal 172.16.48.175:3260
