3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
annotation purposes only and it does not affect the operation of the storage server. See the
InForm OS Command Line Interface Reference or InForm CLI Help for further information. To
create a host with an assigned host persona, see section 6.11.3 Creating a Host with an
Assigned Host Persona.
6.6.1 Creating a Host with a Fiber Channel Path
To create a host with an FC path:
1 Determine the HBA’s WWN by issuing the
showhost command.
2 Issue the
createhost -persona <persona_number> <host_name> <WWN>
command, where:
◆ <persona_number> is the host persona number assigned to the host.
◆ <host_name> is the user-designated name of the host being defined.
◆ <WWN> is the HBA’s WWN.
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.
6.6.2 Creating a Host with an iSCSI Path
To create a host with an iSCSI path:
1 Determine the HBA’s iSCSI Name by issuing the
showport -iscsiname command.
2 Issue the
createhost -iscsi -persona <persona_number> <host_name>
<iSCSI_name>
command, where:
◆ <persona_number> is the host persona number assigned to the host.
NOTE: There should be at least two paths to each host to facilitate updates to the
InServ Storage Server. Failure to create at least two host paths may result in
unnecessary system down-time.
NOTE: See the 3PAR Implementation Guide for recommended practices and
detailed configuration information about using your specific host devices with
the InServ Storage Server.
