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. 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.
The following example of host definition creation depicts a VMware iSCSI initiator iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56 on an ESX host (the only iSCSI initiator for this server in this case) connecting through a VLAN to a pair of HP 3PAR StoreServ Storage iSCSI ports. The host definition is given the name ESX1 and the host persona is set to 6 (Generic-legacy).
1.Issue the HP 3PAR OS CLI showhost command to verify that the host iSCSI initiators are connected to the HP 3PAR StoreServ Storage iSCSI target ports.

2.Issue the HP 3PAR OS CLI createhost command to create the appropriate host definition entry.
#createhost
or:
#createhost
3.Issue the HP 3PAR OS CLI showhost command to verify that the host entry has been created.
#showhost

4.To test the connection, create some temporary virtual volumes and export the VLUNs to the host.
NOTE: See “Allocating Storage for Access by the ESX Host” (page 78) for complete details on creating, exporting and discovering storage for an iSCSI connection.
5.On the ESX iSCSI initiator host, perform a rescan and verify that the disks have been discovered.
