Host Personas
3PAR InForm OS Concepts Guide InForm OS Version 2.3.1
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 iSCSI Enclosure Services (SES) LUN ID 254 for Host Explorer agent support.
Table 6-1 describes the specific functionality for each host persona number. Refer to the 3PAR
InForm OS Configuration Matrix for a list of supported host operating systems.
NOTE: Each host connected to the InServ Storage Server must use a host persona
with the iSCSI Enclosure Services LUN (SESLun) enabled, or the Host Explorer
agent cannot communicate with the InServ Storage Server.
