Modifying Hosts
InForm OS Version 2.3.1 3PAR InForm CLI Administrator’s Manual
◆ <host_name> is the user-designated name of the host being defined.
◆ <iSCSI_Name> is the host iSCSI Name as determined from step 1 above.
If the Host Explorer agent is running on the host, the
createhost -iscsi <host_name>
command automatically creates a host with the path information received from the Host
Explorer agent.
6.6.3 Creating a Host without Assigning a Path
In instances where the HBA’s Fibre Channel WWN or iSCSI Name is unavailable, you can create
a host as a placeholder until the path information becomes available. If the Host Explorer
agent is not running on the host, the
createhost <host_name> command creates a host
without any path information. If the Host Explorer agent is running on the host, the
createhost <host_name> command automatically creates a host with the path information
received from the Host Explorer agent.
The host path information is required to display the device name. If the path information is
not reported from the host to the InServ, then the device name appears as Unknown.
 Issue the createhost <host_name> command, where <host_name> is the user-
designated name of the host being defined.
6.7 Modifying Hosts
You can modify the following parameters and functions of an existing host:
■ Change the host’s name.
■ Add or remove WWNs or iSCSI Names.
■ Add or remove iSCSI CHAP authentication information.
■ Assign a host persona to a host, see section 6.11.4 Assigning a Host Persona to a Host.
The following CLI commands are described in detail in the InForm OS Command Line Interface
Reference and the CLI Help Pages.
