ISCSID(8) BSD System Manager's Manual ISCSID(8)NAME
iscsid -- interface to kernel iSCSI driver
iscsid [-n] [-d lvl]
The iSCSI initiator runs as a kernel driver, and provides access to iSCSI targets running across a network using the iSCSI protocol, RFC
3720. The iscsid utility itself interfaces to the kernel iSCSI driver, and also communicates, using isns(3), with the iSCSI name service
running on other hosts to locate services and iSCSI instances. In normal operation, iscsid is a standard daemon, and will detach from the
controlling terminal using daemon(3) and then loops, reading requests, processing them, and sending responses. Communication takes place
over a Unix domain socket. iscsid exits on receiving a terminate message, (no response to one that is sent to the kernel), or when an error
occurs reading from or writing to the socket.
The -d flag increases the debug level to lvl. Any level above 0 causes iscsid to remain in the foreground, and increases the amount of debug
output. The -n flag makes the daemon single-threaded.
It is envisaged that user-level communication take place with iscsid using the iscsictl(8) utility, rather than directly over its communica-
tion socket. An example of setting up the in-kernel iSCSI initiator is shown in iscsictl(8).

The iscsid utility appeared in NetBSD 6.0.

ISCSI(4) BSD Kernel Interfaces Manual ISCSI(4)NAME
iscsi -- iSCSI initiator
To compile this driver into the kernel, place the following line in the kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
The iscsi subsystem provides the kernel component of an iSCSI initiator. The initiator is the iSCSI client, which connects to an iSCSI tar-
get, providing local access to a remote block device. The userland component is provided by iscsid(8) and both the kernel and userland are
configured using iscsictl(8). The iscsi subsystem is responsible for implementing the "Full Feature Phase" of the iSCSI protocol.
The following variables are available as both sysctl(8) variables and loader(8) tunables:
The number of seconds to wait for the target to respond to a NOP-Out PDU. In the event that there is no response within that time
the session gets forcibly restarted.
The number of seconds to wait for ctld(8) to establish a session. After that time iscsi will abort and retry.
The number of seconds to wait for a login attempt to succeed. After that time iscsi will abort and retry.
The maximum number of outstanding IO requests.
Controls the behavior after an iSCSI connection has been dropped due to network problems. When set to 1, a dropped connection causes
the iSCSI device nodes to be destroyed. After reconnecting, they will be created again. By default, the device nodes are left
intact. While the connection is down all input/output operations are suspended, to be retried after the connection is reestablished.

The iscsi subsystem first appeared in FreeBSD 10.0.
The iscsi subsystem was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.

I have installed Solaris 10 10/08 on sparc machine. I would like to configure iSCSI on that to mount SAN Volumes. Is there any need to install any additional patches for iSCSI to work.

I am running Solaris 10 on a V490. I have Dell EqualLogic SAN attached.
I would like to take full advantage of the iSCSI initiator.
I have a primary network interface and IP addresses for all four SAN ports. Since the four ports are SUN GigaSwift (legacy), I cannot utilize dladm, so I downloaded... (2 Replies)
I have an Equallogic SAN that I connect to from AIX (as well as Windows)
I had configured the connection and created the volumes and filesystems and all was working great.
Then one day, no communication between the SAN and the AIX (I can ping though) Anything I do on the AIX box at this time... (2 Replies)
I have an iSCSI LUN attached to an AIX 5.3 box. It's initial size is 250GB, I just grew it on the SAN to 300GB, but AIX is not seeing the change. Right now I have some processes going and it's eating up the disk space. I need to grow this lun by atleast 30GB otherwise the process with bomb... (5 Replies)
Previous forum threads have noted that AIX cannot use iSCSI disks because it fails when trying to add them to a volume group using mkvg. The failure is caused by AIX's use of the SCSI "WRITE AND VERIFY"(0x2e) command which some iSCSI targets do not support.
We experienced the same problem using... (1 Reply)
I am facing issue with the iSCSI configuration on some of our RHEL 5 servers,
When I restart the iSCSI service, it triggers the RHEL server reboot.

Sorry guys but let me start off by saying I am an AIX noob! I am running AIX 6.1 and recently purchased two iSCSI TOE cards. The plan is to connect these two cards to a Dell EqualLogic SAN and that has two volumes configured for logs and data.
The point of the two cards is to do load balancing... (21 Replies)
I need boot any images from iSCSI and I'd like to boot from linux console of a previous LiveCD booted. Is possible, without gpxe, ipxe firmware or similar? With a simple iSCSI initiator for example? (1 Reply)
