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 system, 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.

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.
The following CLI commands are described in detail in the HP 3PAR Command Line Interface
Reference and the HP 3PAR CLI Help.

Changing a Host Name

To change a host name, issue the sethost -name <new_host_name> <host_name>
command, where:
<new_host_name> is the new name you wish to assign to the existing host.
<host_name> is the original name of the host you are modifying.

Adding Fibre Channel Path WWNs

To add a WWN to an existing host:
1. Determine the HBA's WWN by issuing the showhost command.
2. Issue the createhost -add <host_name> <WWN> command, where:
<host_name> is the name of the host being modified.
<WWN> is the HBA's WWN.
3. Repeat as necessary for any additional WWNs you wish to add to the host definition.

Adding iSCSI Path iSCSI Names

To add an additional iSCSI Name for an existing host:
1. Determine the HBA's iSCSI Name by issuing the showport -iscsiname command.
2. Issue the createhost -add -iscsi <host_name> <iSCSI_name> command, where:
<host_name> is the name of the host being modified.
<iSCSI_Name> is the host iSCSI Name as determined from step 1 above.
3. Repeat as necessary for any additional iSCSI Names you wish to add to the host definition.

Removing Fibre Channel Path WWNs

To remove a WWN from an existing host, issue the removehost <host_name> <WWN>
command, where:
<host_name> is the name of the host being modified.
<WWN> is the FC path being removed.
