Creating the Host Definition
Before connecting the ESX host to the HP 3PAR StoreServ Storage, a host definition needs to be
created that specifies a valid host persona (host mode) for each HP 3PAR StoreServ Storage port
that is to be connected to a host HBA port through a fabric or direct connection.
ESX/ESXi uses the generic legacy host persona of 6 for HP 3PAR OS 3.1.1 or earlier.
As of HP 3PAR OS 3.1.2, a second host persona 11 (VMware), which enables asymmetric
logical unit access (ALUA) is available.
Host persona 11 (VMware) is recommended for new ESX/ESXi installations and is required
for ESX/ESXi hosts configured as part of a HP 3PAR Peer Persistence configuration.
Host persona 11 (VMware) is required for FCoE end-to-end (FCoE target) configurations.
For ESX/ESXi with HP 3PAR Remote Copy, refer to the Remote Copy Users Guide for the
appropriate host persona to use in specific Remote Copy configurations.
NOTE: When changing an existing host persona from 6 to 11, a host reboot is required tor the
change to take effect. This is an offline process. See “Configuring ESX/ESXi Multipathing for Round
Robin via SATP PSP” (page 40) for the detailed procedure, as the host persona change should
coincide with changing the SATP rules on the host as well.
For both host persona 6 and persona 11, see the appropriate chapters in this guide for host server
FCoE setup considerations.
1. To display available host personas, issue the following command:
# showhost -listpersona
2. To create host definitions, issue the createhost command with the -persona option to
specify the persona and the host name.
For HP 3PAR OS 3.1.1 or earlier:
# createhost -persona 6 ESXserver1 10000000C9724AB2 10000000C97244FE
For HP 3PAR OS 3.1.2:
# createhost -persona 11 ESXserver1 10000000C9724AB2 10000000C97244FE
3. To verify that the host has been created, issue the showhost command.
For HP 3PAR OS 3.1.1 or earlier, using persona 6:
# showhost
Id Name Persona -WWN/iSCSI_Name- Port
0 ESXserver1 Generic-legacy 10000000C9724AB2 --- 10000000C97244FE ---
For HP 3PAR OS 3.1.2, using persona 11:
# showhost
Id Name Persona -WWN/iSCSI_Name- Port
0 ESXserver2 VMware 100000051EC33E00 --- 100000051EC33E01 ---
