Hello, Will it have any impact if I chose host as Windows Server 2008 in 3PAR IMC for the server having OS windows server 2012. Regards, KK |

It depends: When you pick an OS from the drop down... the IMC code is translating that to an actual persona number that you can see on the next line. I presume this will change with versions with IMC, and the IMC being aware of the Inserv version you are connected to as well. IMC version 4.5.1.13 managing an Inserv version 3.1.2 is mapping Windows 2008 and 2012 both to persona 2. However I would guess that newer versions of both would choose persona 15 instead. The CLI admin guide for the specific Inserv version you are on has a good section on the personas. The upgrade implementation guides to take you to next versions will detail any persona changes that may be required as well. |

Thanks Richard Sir, I have implementation guide for windows servers. Luckily the host perona remains same for Windows 2008 and 2012 from 3.1.2 (MU3). Could you please also explain what does Host Persona mean? Regards, KK |

The Host Persona is determining what SCSI capabilities are supported by the initiator and allows multiple hosts of differing OS's to connect to the same target ports. The 3.2.1 personas are as follows: 1 Generic Linux, Windows, and Solaris UARepLun, SESLun 2 Generic-ALUA Linux, Windows, and Solaris UARepLun, ALUA, SESLun 6 Generic-Legacy Linux, Windows, and Solaris None 7 HPUX-Legacy HP-UX VolSetAddr, Lun0SCC 8 AIX-Legacy AIX NACA 9 Egenera Egenera, NetApp SoftInq 10 NetApp ONTAP Data ONTAP SoftInq 11 VMware Linux and Windows SubLun, ALUA 12 OpenVMS OpenVMS UARepLun, RTPG, SESLun, LunoSCC 13 HPUX HP-UX UARepLun, VolSetAddr, SESLun, ALUA, LunoSCC 15 WindowsServer Windows UARepLun, SESLun, ALUA, WSC -Aaron |

The Host Persona setting is used for things like correct Error-handling between the Host and Array. It has nothing to do with performance or something like that. If the Host Persona's are wrong set or must be changed you must have a look @ the Host Persona Migration Guide with the correct steps to do that. |

Can someone please explain exactly what Host Persona is/does? Documentation is unclear and this is new to me. Thanks in advance! |

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 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. |
