HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

Modifying Host Sets
• To change the name of a host set, issue the sethostset <new_name> <set_name>
command, where:
◦ <new_name> is the new name of the host set.
◦ <set_name> is the name of the host set being modified.
For a complete list of options available for the sethostset command, see the HP 3PAR InForm
OS Command Line Interface Reference and InForm OS CLI Help.
Removing Host Sets
If a host is removed from a host set, the removed host loses all the rights of the host set and cannot
access volumes exported to the host set.
• To remove a host set from the system, or to remove hosts from a set, issue the removehostset
<set_name> <host_names> command, where:
◦ <set_name> is the name of the host set being removed or modified.
◦ <host_names> are the names of the hosts being removed from the <set_name> host
set. This specifier is optional and it is not required if you are removing the entire set.
For a complete list of options available for the removehostset command, see the HP 3PAR
InForm OS Command Line Interface Reference and InForm OS CLI Help.
Managing Host Personas
Host personas are a set of behaviors that permit hosts connected to FC or iSCSI ports on the system
to deviate from the default host behavior. By assigning a persona to a host, multiple host types
that require distinct customized responses can share a single system port. For example, hosts
running Windows, Linux, and AIX operating systems can all connect to the same system port. This
simplifies connecting hosts to the system and reduces management costs related to complex host
connections.
A host persona defines the custom responses for certain SCSI commands and does not affect any
of the FC port settings. Host personas are tied to the host name and identified by the host persona
number. You can define the host persona for a host by setting the host persona number when the
host is created with the createhost command, or modify it later with the sethost command.
The host management CLI commands are described in detail in the HP 3PAR InForm OS Command
Line Interface Reference and the CLI Help Pages.
Different host personas have different functions and support different host operating systems. The
specific host persona is designated by the host persona number. Depending on the selected host
persona number, the following additional capabilities are supported:
• UARepLun - Sends an unit attention when the LUN list changes due to adding or removing
VLUNs.
• RTPG - Enables the Report Target Port Group (RTPG) command and asymmetric state change
unit attention when path counts change due to adding or removing ports in the host's definition.
• VolSetAddr - Enables HPUX Volume Set Addressing (VSA).
• SoftInq - Enables inquiry data formats for hosts such as Egenera and NetApp.
• NACA - Enables Normal Auto Contingent Allegiance (NACA) bit for AIX.
• SESLun - Enables SCSI Enclosure Services (SES) LUN ID 254 for Host Explorer agent support.
NOTE: Each host connected to the system must use a host persona with the SCSI Enclosure
Services LUN (SESLun) enabled, or the Host Explorer agent cannot communicate with the system.
