Creating a Host
3PAR InForm OS CLI Administrator’s Manual InForm OS Version 2.2.4
X To display WWNs and/or iSCSI Names from connected devices, issue the showhost
command.
However, you can also use the InForm CLI to add new WWNs or iSCSI Names for unestablished
host paths and assign them to a host before they are physically connected.
5.2 Creating a Host
When creating a new host, you are actually defining the characteristics of a new host path
from the InServ Storage Server to the host. Defining host characteristics involves the
assignment of a name to a host and assignment of a path to that host. Two types of host paths
can be assigned: FC or iSCSI paths.
5.2.1 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 <host_name> <WWN> command, where:
 <host_name> is the user-designated name of the host being defined.
 <WWN> is the HBA’s WWN.
5.2.2 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 <host_name> <iSCSI_name> command, where:
 <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.
NOTE: To maintain system redundancy, 3PAR recommends establishing a physical
connection between your host and node pairs.
