.SH DESCRIPTION
The iscsiadm utility is a command-line tool allowing discovery and login
to iSCSI targets, as well as access and management of the open-iscsi
database.
.PP
Open-iscsi does not use the term \fInode\fR as defined by the iSCSI RFC,
where a node is a single iSCSI initiator or target. Open-iscsi uses the
term \fInode\fR to refer to a portal on a target.
.PP
For \fIsession\fR mode, a session id (\fIsid\fR) is used. The \fIsid\fR of a session can be
found by running \fIiscsiadm \-m session \-P 1\fR. The session id and sysfs
path are not currently persistent and is partially determined by when the
session is setup.
.SH NOTES
.PP
Many of the node and discovery operations require that the iSCSI
daemon (iscsid) be running. If running on a system that uses systemd,
the daemon may start up automatically, if enabled, when needed.
.PP
Open-iscsi has two groups of files it needs to store or get access to,
while running: the \fBHOMEDIR\fR and the \fBDBROOT\fR. The following
describes them:
.TP
.B Home Directory
The \fIhome directory\fR for open-iscsi is @HOMEDIR@. This is
where it keeps its configuration file (\fIiscsid.conf\fR) and its
initiator name file (\fIinitiatorname.iscsi\fR).
.TP
.B Database Root Directory
The \fIdatabase root directory\fR for open-iscsi is @DBROOT@. This
is where it keeps its flat database files, such as its list of \fInode\fRs
(see below).
.SH OPTIONS
.TP
\fB\-a\fR, \fB\-\-ip=\fIipaddr\fP
\fIipaddr\fR can be IPv4 or IPv6.
.IP
This option is only valid for \fIping\fR submode.
.TP
\fB\-A\fR, \fB\-\-portal_type=\fI[ipv4|ipv6]\fR
Specify the portal type for the new flash node entry to be created.
.IP
This option is only valid for \fIflashnode\fR submode of \fIhost\fR mode and only with \fInew\fR operation.
.TP
\fB\-b\fR, \fB\-\-packetsize=\fIpacketsize\fP
Specify the ping \fIpacketsize\fR.
.IP
This option is only valid for \fIping\fR submode.
.TP
\fB\-c\fR, \fB\-\-count=\fIcount\fP
\fIcount\fR specifies the number of ping iterations.
.IP
This option is only valid for \fIping\fR submode.
.TP
\fB\-C\fR, \fB\-\-submode=\fIop\fP
Specify the submode for mode. \fIop\fR must be name of submode.
.IP
Currently iscsiadm supports \fIping\fR as a submode for \fIiface\fR. For example:
.IP
iscsiadm \-m iface \-I ifacename \-C ping \-a ipaddr \-b packetsize \-c count \-i interval
.IP
For \fIhost\fR, it supports \fIchap\fR, \fIflashnode\fR and \fIstats\fR as submodes. For example:
.IP
iscsiadm \-m host \-H hostno \-C chap \-x chap_tbl_idx \-o operation
.IP
iscsiadm \-m host \-H hostno \-C flashnode \-x flashnode_idx \-o operation
.IP
iscsiadm \-m host \-H hostno \-C stats
.TP
\fB\-d\fR, \fB\-\-debug=\fIdebug_level\fP
print debugging information. Valid values for \fIdebug_level\fR are 0 to 8.
.TP
\fB\-h\fR, \fB\-\-help\fR
display help text and exit
.TP
\fB\-H\fR, \fB\-\-host=\fI[hostno|MAC]\fR
The \fIhost\fR argument specifies the SCSI host to use for the operation. It can be
the scsi host number assigned to the host by the kernel's scsi layer, or the
MAC address of a scsi host.
.TP
\fB\-i\fR, \fB\-\-interval=\fIinterval\fP
\fIinterval\fP specifies the delay between two ping iterations.
.IP
This option is only valid for \fIping\fR submode.
.TP
\fB\-I\fR, \fB\-\-interface=\fI[iface]\fR
The \fIinterface\fR argument specifies the iSCSI interface to use for the operation.
iSCSI interfaces (\fIiface\fR) are defined in @DBROOT@/ifaces. For hardware
iSCSI (e.g. qla4xxx) the \fIiface\fR configuration must have the hardware address
(\fIiface.hwaddress\fR = port's MAC address)
and the driver/transport_name (\fIiface.transport_name\fR). The \fIiface\fR's name is
then the filename of the iface configuration. For software iSCSI, the iface configuration
must have either the hardware address (\fIiface.hwaddress\fR), or the network
layer's interface name (\fIiface.net_ifacename\fR), and it must have the
driver/transport_name.
.IP
The available drivers/iscsi_transports are \fItcp\fR (software iSCSI over TCP/IP),
\fIiser\fR (software iSCSI over InfiniBand),
\fIqla4xxx\fR (Qlogic 4XXXX and 82XXX HBAs),
\fIcxgb3i\fR and \fIcxgb4i\fR (Chelsio T3 and T4 adapters),
\fIbnx2i\fR (QLogic Netextreme II adapters),
\fIbe2iscsi\fR (Emulex 10G adapter),
\fIqedi\fR (QLogic QEDI 25/40/100Gb adapter), and
\fIocs\fR (Emulex One Connect storage).
Some of these are considered experimental, as they are not fully tested.
.IP
The \fIhwaddress\fR is the MAC address or for software iSCSI it may be the special
value \fIdefault\fR which directs the initiator to not bind the session to a
specific hardware resource and instead allow the network or InfiniBand layer
to decide what to do. There is no need to create an iface configuration with the default
behavior. If you do not specify an \fIiface\fR, then the default behavior is used.
.IP
As mentioned above there is a special iface name \fIdefault\fR. There are
others which do not bind the session to a specific card, but instead bind
the session to the transport:
\fIiser\fR,
\fIcxgb3i\fR,
\fIcxgb4i\fR, and
\fIbnx2i\fR.
.IP
In \fIdiscovery\fR mode multiple interfaces can be specified by passing in
multiple \fI\-I/\-\-interface\fR instances. For example:
.IP
\fBsh#\fR iscsiadm \-m discoverydb \-t st \-p ip:port \-I iface0 \-I iface2 \-\-discover
.IP
Will direct iscsiadm to setup the node db to create records which will create
sessions through the two interfaces passed in.
.IP
In \fInode\fR mode, only a single interface is supported in each call to iscsiadm.
.IP
This option is valid for \fIdiscovery\fR, \fInode\fR and \fIiface\fR modes.
.TP
\fB\-k\fR, \fB\-\-killiscsid=\fI[priority]\fR
Currently \fIpriority\fR must be zero. This will immediately stop all iscsid
operations and shutdown iscsid. It does not logout any sessions. Running
this command is the same as doing \fIkillall iscsid\fR. Neither should
normally be used, because if iscsid is doing error recovery or if there
is an error while iscsid is not running, the system may not be able to recover.
This command and iscsid's SIGTERM handling are experimental.
.TP
\fB\-D\fR, \fB\-\-discover\fR
Discover targets using the discovery record with the \fIrecid\fR matching
the the discovery type and portal passed in. If there is no matching record,
it will be created using the iscsid.conf discovery settings.
This must be passed in to \fIdiscoverydb\fR mode to instruct iscsiadm to perform
discovery.
.IP
This option is only valid for \fISendTargets\fR discovery mode.
.TP
\fB\-l\fR, \fB\-\-login\fR
For \fInode\fR and \fIfw\fR modes, login to a specified record. For \fIdiscovery\fR mode,
login to all discovered targets.
.IP
This option is only valid for \fIdiscovery\fR, \fInode\fR, and \fIfw\fR modes.
For \fIfw\fR mode only, \fIname\fR and \fIvalue\fR pairs can optionally be passed in,
so that those values get used for the sessions created. In this case, no \fIop\fR
is needed, since \fIupdate\fR is assumed.
.TP
\fB\-L\fR, \fB\-\-loginall=\fI[all|manual|automatic|onboot]\fR
For \fInode\fR mode, login to all sessions with the node or conn startup values passed
in or all running session, except ones marked \fIonboot\fR, if \fIall\fR is passed in.
.IP
This option is only valid for \fInode\fR mode (it is valid but not functional
for \fIsession\fR mode).
.TP
\fB\-W\fR, \fB\-\-\-no_wait\fR
In \fInode\fR, \fIdiscovery\fR, or \fIfw\fR (firmware) mode,
do not wait for a response from the target(s).
This means that success will be returned if the command is able to
send the login requests, whether or not they succeed. In this case, it will
be up to the caller to poll for success (i.e. session creation).
.TP
\fB\-m\fR, \fB\-\-mode \fIop\fR
specify the mode. \fIop\fR
must be one of \fIdiscovery\fR, \fIdiscoverydb\fR, \fInode\fR, \fIfw\fR,
\fIhost\fR, \fIiface\fR or \fIsession\fR.
.IP
If no other options are specified: for \fIdiscovery\fR, \fIdiscoverydb\fR and
\fInode\fR mode, all of their respective records are displayed; for \fIsession\fR mode,
all active sessions and connections are displayed; for \fIfw\fR mode, all boot
firmware values are displayed; for \fIhost\fR mode, all iSCSI hosts are displayed;
and for \fIiface\fR mode, all interfaces setup in @DBROOT@/ifaces are displayed.
.TP
\fB\-n\fR, \fB\-\-name=\fIname\fR
In \fInode\fR mode, specify a field \fIname\fR in a record. In \fIflashnode\fR submode
of \fIhost\fR mode, specify name of the flash node parameter.
.IP
For use with the \fIupdate\fR operator.
.TP
\fB\-o\fR, \fB\-\-op=\fIop\fR
Specifies a database operator \fIop\fR. \fIop\fR must be one of
\fInew\fR, \fIdelete\fR, \fIupdate\fR, \fIshow\fR or \fInonpersistent\fR.
.IP
For \fIiface\fR mode, \fIapply\fR and \fIapplyall\fR are also applicable.
.IP
For \fIflashnode\fR submode of \fIhost\fR mode, \fIlogin\fR and \fIlogout\fR are also applicable.
.IP
This option is valid for all modes except \fIfw\fR. Delete should not be used
on a running session. If it is iscsiadm will stop the session and then delete the
record.
.IP
An \fIop\fR of \fInew\fR creates a new database record for a given object. In \fInode\fR mode, the
\fIrecid\fR is the target name and portal (IP:port). In \fIiface\fR mode, the \fIrecid\fR
is the iface name. In \fIdiscovery\fR mode, the \fIrecid\fR is the portal and
discovery type.
.IP
In \fIsession\fR mode, the \fInew\fR operation logs in a new session using
the same node database and iface information as the specified session.
.IP
In \fIdiscovery\fR mode, if the \fIrecid\fR and \fInew\fR operation is passed in,
but the \fI\-\-discover\fR argument is not passed in, then iscsiadm will only create a
discovery record (it will not perform discovery). If the \fI\-\-discover\fR
argument is passed in with the portal and discovery type, then iscsiadm
will create the discovery record if needed, and it will create records
for portals returned by the target that do not yet have a node DB record.
.IP
Setting \fIop\fR to \fIdelete\fR deletes the specified \fIrecid\fR. In \fIdiscovery\fR mode, if
iscsiadm is performing discovery, it will delete records for portals that
are no longer returned.
.IP
Setting \fIop\fR to \fIupdate\fR will update the \fIrecid\fR with \fIname\fR to the specified
\fIvalue\fR. In discovery mode, if iscsiadm is performing discovery the
\fIrecid\fR, \fIname\fR and \fIvalue\fR arguments are not needed. The
update operation will operate on the portals returned by the target,
and will update the node records with information from the configuration file and
command line.
.IP
The \fIop\fR value of \fIshow\fR is the default behaviour for \fInode\fR,
\fIdiscovery\fR and \fIiface\fR mode. It is
also used when there are no commands passed into \fIsession\fR mode and a
running \fIsid\fR is passed in.
If \fIname\fR and \fIvalue\fR are passed in, they are currently ignored in \fIshow\fR mode.
.IP
An \fIop\fR value of \fInonpersistent\fR instructs iscsiadm to not manipulate the node DB.
.IP
An \fIop\fR value of \fIapply\fR will cause the network settings to take effect on the specified iface.
.IP
An \fIop\fR value of \fIapplyall\fR will cause the network settings to take effect on all the
ifaces whose MAC address or host number matches that of the specific host.
.IP
An \fIop\fR value of \fIlogin\fR will log into the specified flash node entry.
.IP
An \fIop\fR value of \fIlogout\fR does the logout from the given flash node entry.
.TP
\fB\-p\fR, \fB\-\-portal=\fIip[:port]\fR
Use target portal with IP address \fIip\fR and port \fIport\fR. If \fIport\fI is not passed
in the default value of 3260 is used.
.IP
IPv6 addresses can be specified as \fI[ddd.ddd.ddd.ddd]:port\fI or \fIddd.ddd.ddd.ddd\fR.
.IP
Hostnames can also be used for the \fIip\fI argument.
.IP
This option is only valid for \fIdiscovery\fR, or for \fInode\fR operations with
the \fInew\fR operator.
.IP
This should be used along with \fI\-\-target\fR in \fInode\fR mode, to specify what
the open-iscsi documents refer to as a node or node record. Note: open-iscsi's
use of the word node, does not match the iSCSI RFC's iSCSI Node term.
.TP
\fB\-P\fR, \fB\-\-print=\fIprintlevel\fR
If in \fInode\fR mode print nodes in tree format. If in \fIsession\fR mode print
sessions in tree format. If in \fIdiscovery\fR mode print the nodes in
tree format.
.TP
\fB\-T\fR, \fB\-\-targetname=\fItargetname\fR
Use target \fItargetname\fR.
.IP
This should be used along with \fI\-\-portal\fR in \fInode\fR mode, to specify what
the open-iscsi documents refer to as a node or node record. Note: open-iscsi's
use of the word node, does not match the iSCSI RFC's iSCSI Node term.
.TP
\fB\-r\fR, \fB\-\-sid=\fIsid | sysfsdir\fR
Use session ID \fIsid\fR. The session ID of a session can be found from running
iscsiadm in session mode with the \fI\-\-info\fR argument.
.IP
Instead of a session ID, a sysfs path containing the session can be used.
For example using one of the following:
/sys/devices/platform/hostH/sessionS/targetH:B:I/H:B:I:L,
/sys/devices/platform/hostH/sessionS/targetH:B:I, or
/sys/devices/platform/hostH/sessionS, for the \fIsysfsdir\fR argument would
result in the session with session ID \fIS\fR to be used.
.IP
\fIsid | sysfsdir\fR is only required for \fIsession\fR mode.
.TP
\fB\-R\fR, \fB\-\-rescan\fR
In \fIsession\fR mode, if \fIsid\fR is also passed in, rescan the session.
If no \fIsid\fR has been passed in rescan all running sessions.
.IP
In \fInode\fR mode, rescan a session running through the target, portal, iface
tuple passed in.
.TP
\fB\-s\fR, \fB\-\-stats\fR
Display session statistics.
This option when used with \fIhost\fR mode, displays host statistics.
.TP
\fB\-S\fR, \fB\-\-show\fR
When displaying records, do not hide masked values, such as the CHAP
secret (password).
.IP
This option is only valid for \fInode\fR and \fIsession\fR mode.
.TP
\fB\-t\fR, \fB\-\-type=\fItype\fR
\fItype\fR must be \fIsendtargets\fR (or abbreviated as \fIst\fR),
\fIisns\fR (if enabled), or \fIfw\fR. See the \fBDISCOVERY TYPES\fR section.
.IP
This option is only valid for \fIdiscovery\fR mode.
.TP
\fB\-u\fR, \fB\-\-logout\fR
Logout for the specified record.
.IP
This option is only valid for \fInode\fR and \fIsession\fR mode.
.TP
\fB\-U\fR, \fB\-\-logoutall=\fI[all,manual,automatic|onboot]\fR
Logout of all sessions with the node or conn startup values passed in or all
running sessions, except ones marked \fIonboot\fR, if \fIall\fR is passed in.
.IP
This option is only valid for \fInode\fR mode (it is valid but not functional
for \fIsession\fR mode).
.TP
\fB\-v\fR, \fB\-\-value=\fIvalue\fR
Specify a \fIvalue\fR for use with the \fIupdate\fR operator, or for firmware login mode.
.IP
This option is only valid for \fInode\fR mode and \fIflashnode\fR submode of \fIhost\fR mode.
.TP
\fB\-V\fR, \fB\-\-version\fR
Display version and exit.
.TP
\fB\-x\fR, \fB\-\-index=\fIindex\fR
Specify the \fIindex\fR of the entity to operate on.
.IP
This option is only valid for \fIchap\fR and \fIflashnode\fR submodes of \fIhost\fR mode.
.SH DISCOVERY TYPES
iSCSI defines 3 discovery types: \fISendTargets\fR, \fISLP\fR, and \fIiSNS\fR.
\fISLP\fR is not widely supported, and not supported by this pacakge.
\fiSNS\fR supported depends on build options, but is enabled by default.
.PP
A special discovery type called
.I fw
(for firmware) is also supported, for discovering firmware interfaces,
and populating the interface database in the process.
.TP
.B
SendTargets
A native iSCSI protocol which allows each iSCSI
target to send a list of available targets to the initiator.
.TP
.B
iSNS
iSNS (Internet Storage Name Service) records information about storage
volumes within a larger network. To utilize iSNS, pass the address and
optionally the port of the iSNS server to do discovery to.
.TP
.B
fw
Firmware mode.
Several NICs and systems contain a mini iSCSI initiator which can be used
for boot. To get the values used for boot the \fIfw\fR option can be used.
Doing \fIfw\fR discovery does not store persistent records in the node or
discovery DB, because the values are stored in the system's or NIC's
resource.
.IP
Performing \fIfw\fR discovery will print the portals, like with other discovery
methods. To see other settings like CHAP values and initiator settings,
like you would in \fInode\fR mode, run \fIiscsiadm \-m fw\fR.
.SH EXIT STATUS
On success 0 is returned. On error one of the return codes below will
be returned.
.PP
Commands that operate on multiple objects (sessions, records, etc),
iscsiadm/iscsistart will return the first error that is encountered.
iscsiadm/iscsistart will attempt to execute the operation on the objects it
can. If no objects are found ISCSI_ERR_NO_OBJS_FOUND is returned.
