Options not associated with a particular subcommand are described under OPTIONS. .sp .LP \fBiscsiadm\fR works only when the following service is online: .sp .in +2 .nf svc:/network/iscsi/initiator:default .fi .in -2 .sp .sp .LP The \fBiscsiadm\fR command supports the following subcommands, which are described in detail in subsections that follow: .sp .ne 2 .mk .na \fB\fBadd\fR\fR .ad .RS 10n .rt Adds element(s) to an object. .RE .sp .ne 2 .mk .na \fB\fBlist\fR\fR .ad .RS 10n .rt Lists element(s) of an object. .RE .sp .ne 2 .mk .na \fB\fBmodify\fR\fR .ad .RS 10n .rt Modifies attributes of an object. .RE .sp .ne 2 .mk .na \fB\fBremove\fR\fR .ad .RS 10n .rt Removes an element from an object. .RE .sp .LP The \fBiscsiadm\fR subcommands operate on a \fIdirect-object\fR.

The command supports the Challenge Handshake Authentication Protocol (CHAP) for authentication. .SS "\fBadd\fR Subcommand" .sp .LP The syntax for the \fBadd\fR subcommand is: .sp .in +2 .nf # iscsiadm add \fIdirect_object\fR [\fIoperands\fR...] .fi .in -2 .sp .LP The \fBadd\fR subcommand adds the following \fIdirect_object\fRs: .sp .ne 2 .mk .na \fB\fBdiscovery-address\fR \fIdiscovery-address\fR [...]\fR .ad .sp .6 .RS 4n Adds a target to a list of discovery addresses. A discovery address (as in the syntax shown below) is an IP \fIaddress\fR:\fIport\fR combination used in a SendTargets discovery session. Using this discovery approach, a target device can inform an initiator of the target address and target name of each target exposed by that device. Connection to a target is not attempted unless the SendTargets method of discovery has been enabled on the host. You enable this method with the \fBmodify\fR subcommand. .sp The \fIdiscovery-address\fR parameter is formatted as: .sp .in +2 .nf <\fIIP address\fR>[:\fIport\fR] .fi .in -2 If \fIport\fR is not specified, the default of 3260 will be used. .RE .sp .ne 2 .mk .na \fB\fBisns-server\fR \fIisns-server\fR [...]\fR .ad .sp .6 .RS 4n Add an iSNS server to the list of iSNS server addresses.
