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
Command Line Interface Reference and the HP 3PAR CLI Help.

Managing Host Personas

A host persona is a set of behaviors that allows hosts that are 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 that run 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 iSCSI 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 set the host persona number when the host is created or modify it later. Use the
HP 3PAR CLI commands or the HP 3PAR Management Console to display, create, modify, and
remove host personas. See the HP 3PAR Command Line Interface Administrator's Manual or the
HP 3PAR Management Console Online Help for instructions on displaying, creating, modifying,
and removing host personas.
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 a unit attention when the VLUNs are added to or removed from the LUN
list.
ALUA—Enables the asymmetric logical unit access (ALUA) 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 the Normal Auto Contingent Allegiance (NACA) bit for AIX.
SESLun—Enables iSCSI Enclosure Services (SES) LUN ID 254 for Host Explorer agent support.
SubLun—Enables SCSI two-level LUN addressing.
NOTE:
Each host connected to the system must use a host persona with the SESLun enabled, or
the Host Explorer agent cannot communicate with the system.
