• For ESX/ESXi hosts with HP 3PAR Remote Copy, see the Remote Copy Users Guide for the
appropriate host persona to use in specific Remote Copy configurations. This document is
available on the HP SC website:

• Host Persona 6 will not be supported for any version of VMware ESX with 3PAR OS versions
after 3PAR OS 3.1.3 and its MUs. HP recommends that customers migrate their ESX
configurations on 3PAR to Host Persona 11 with 3PAR OS 3.1.2 or later.
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’s iSCSI initiators are
connected to the HP 3PAR StoreServ Storage iSCSI target ports.
# showhost
Id Name Persona ----------------WWN/iSCSI_Name---------------- Port
-- -- iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56 0:1:2
-- -- iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56 1:1:2
-- -- iqn.1998-01.com.vmware:dl360g8-02-42b20fff 0:1:2
-- -- iqn.1998-01.com.vmware:dl360g8-02-42b20fff 1:1:2
2. Issue the HP 3PAR OS CLI createhost -iscsi -persona <hostpersona>
<hostname> <iscsi_initiator_name> command to create the appropriate host definition
entry.
# createhost -iscsi -persona 6 ESX1 iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56
or:
# createhost -iscsi -persona 11 ESX2 iqn.1998-01.com.vmware:dl360g8-02-42b20fff
3. Issue the HP 3PAR OS CLI showhost command to verify that the host entry has been created.
# showhost
Id Name Persona ----------------WWN/iSCSI_Name---------------- Port
0 ESX1 Generic-legacy iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56 0:1:2
iqn.1998-01.com.vmware:sqahpbc02icm5-40e25c56 1:1:2
1 ESX2 VMware iqn.1998-01.com.vmware:dl360g8-02-42b20fff 0:1:2
iqn.1998-01.com.vmware:dl360g8-02-42b20fff 1:1:2
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 76) 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.
