iscsid will only perform rediscovery when it gets a SCN from the server. along with their ip, port, tpgt and iqn values. This includes MAC, TCP/IP, ECC & iSCSI statistics. the MAC address of the host or the host number. Assign a name to the initiator in /etc/iscsi/initiatorname.iscsi. the output above, which is "iface.ipaddress". If [op] is passed in and the value is "delete", iscsiadm will delete records for portals that, the portals found in the node DB. *This should be fixed in the some future version of Open-iSCSI*, For compatibility reasons, when you run iscsiadm to do discovery, it, will check for interfaces in /etc/iscsi/iscsi/ifaces that are using, tcp for the iface.transport, and it will bind the portals that are discovered, so that they will be logged in through those ifaces. The following parameters are used for authenticating a login session of an initiator to a target: If your target has two-way authentication enabled then those lines also need to be edited: If your target requires authentication to get the list of its nodes (most will not) then following lines should be edited: On success information about nodes and target will be saved on your initiator. # events in the proper format, so they may not get handled. The [name] and [value] pairs must be provided for the, params that need to be updated. Logout from a iscsi target. Open-iSCSI Configuration and Administration Utility, ======================================================, Open-iSCSI persistent configuration is stored in a number of, directories under a configuration root directory, using a flat-file. For tcp or iser, this would allow the network layer to decide what is, Note that for this command, the Target Portal Group Tag (TPGT) should. 15 ISCSI_ERR_DATA_DGST iSCSI Data Digest error. Copied! If you are looking for something shorter, like just the sid to node mapping. This is the default. Assign a name to the initiator in /etc/iscsi/initiatorname.iscsi. - Manipulate SendTargets DB: Create new SendTargets discovery record or, overwrite an existing discovery record with iscsid.conf, iscsiadm -m discoverydb -t sendtargets -p 192.168.1.1:3260 -o new. Its OK if this file, does not exist, in which case compiled-in default configuration will take place. If a NOP-Out times out, the, iSCSI layer will respond by failing the connection and starting the, replacement_timeout.
