3PAR Persona

[MUDBOY]

Host personas are a set of behaviors that permit hosts connected to FC or iSCSI ports on the system to deviate from the efault 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 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 LUN list changes due to adding or removing VLUNs.
• 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 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.
