isnsadm options

isnsadm subcommand [subcommand_options] [operand]

The isnsadm command is the command-line interface to the Internet Storage Name Service (iSNS) server. isnsadm comprises a set of subcommands, described in their own section, each of which accomplishes one of the iSNS server management functions.

For any operations that will change the iSNS configurations the solaris.isnsmgr.write authorization is required. Refer to isns(8). For read operations, the command does not require special authorizations.

isnsadm has a set of general options and a set of subcommand-specific options. The first category is described under OPTIONS; the second category is described in the context of each subcommand description.

The following options are supported: -?, --help

-V, --version

The following operands are used by one or more isnsadm subcommands. iscsi-node-name

discovery-domain-name discovery-domain-set-name

When a subcommand is invoked with multiple operands and there are failures on one or more, but not all, operands, isnsadm displays a generic message indicating partial failure, with list of failed operands. An error on a specific operand can be found by issuing the same subcommand on the failing operand.
