NexentaStor 1.0.7 (Default branch)
ImageNexentaStor leverages the ZFS file system and is optimized for use in 2nd-tier NAS and iSCSI applications requiring open, low cost, high performance storage as well as dramatically simplified provisioning, expansion, backup, replication, and archiving. It is also used as a primary NAS in businesses that wish to expand at closer to commodity pricing. It supports unlimited snapshots, snapshot mirroring (replication), block level mirroring, integrated search, and easy management of extremely large storage pools.License: Other/Proprietary License with Free TrialChanges:
ZFS Write Once, Read Many (WORM) support. Auto-services automated retry once/if remote peer becomes reachable. The create and grow volume process handles cache devices. SMTP over TLS support. The auto-CDP service has multiple improvements and fixes. iSCSI target improvements, and many fixes for the VMware ESX data store. A new plugin: ATA over Ethernet (AOE). ZFS autoreplace: the ability to hot plug a drive when replaced.Image

LIBISCSI(3)						   BSD Library Functions Manual 					       LIBISCSI(3)

NAME

     int
     iscsi_initiator_set_defaults(iscsi_initiator_t *initiator);

     int
     iscsi_initiator_start(iscsi_initiator_t *initiator);

     int
     iscsi_initiator_discover(iscsi_initiator_t *initiator, char *x, uint64_t a, int b);

     int
     iscsi_initiator_shutdown(iscsi_initiator_t *initiator);

     int
     iscsi_initiator_setvar(iscsi_initiator_t *initiator, const char *name, const char *value);

     char *
     iscsi_initiator_getvar(iscsi_initiator_t *initiator, const char *name);

DESCRIPTION

     libiscsi is a library interface to the iSCSI target and initiator.  This conforms to IETF RFC 3720.  The corresponding command line utilities
     for libiscsi are iscsi-initiator(8) and iscsi-target(8).

     In normal operation, a process acting as a target (i.e. presenting storage to the network) will call iscsi_target_set_defaults() and will
     then set various values using the iscsi_target_setvar() function.	The value of a variable can be retrieved at any time using the
     iscsi_target_getvar() function.  When all of the variables have been set, the iscsi_target_start() function is called, and the block storage
     will be served up by the process.

     A useful illustration of the use of these functions can be found in the source code to the iscsi-target(8) utility.

     The libiscsi library also provides an implementation of the client end of the iSCSI subsystem, which is known as the initiator.  The process
     acting as an initiator will first call the iscsi_initiator_set_defaults() function, to set default values for the initiator variables.  Once
     all the values have been set to the user preferences using the iscsi_initiator_setvar() function, then the iscsi_initiator_start() function
     is called.

     The libiscsi library can be used to perform iSCSI device discovery by calling the iscsi_initiator_discovery() function.  This will return a
     list of all the iSCSI targets which are serving up block storage according to the variables which have already been set.

HISTORY

     The libiscsi library first appeared in NetBSD 4.0.  This programmatic interface to the iSCSI subsystem first appeared in NetBSD 6.0.
