5 Managing Ports and Hosts Overview The system sees a host as a set of initiator port World Wide Names (WWNs) or iSCSI Names. Hosts that are physically connected to ports on the system are automatically detected. The FC port WWNs and iSCSI port iSCSI Names are displayed in the HP 3PAR CLI. You can also add new WWNs or iSCSI Names for unestablished host paths and assign them to a host before they are physically connected. These WWNs or iSCSI Names do not need to be associated with target ports on the system controller nodes. This allows for plug-and-play functionality that avoids the need for manual reconfiguration after connecting new hosts. FCoE connectivity is supported on HP 3PAR StoreServ 10000 Storage systems and HP 3PAR StoreServ 7000 Storage systems through the use of Converged Network Adapters (CNA). CNA ports can be configured to be used as FCoE or iSCSI ports. 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 time related to complex host connections. For more information about ports, hosts, and host personas, see the HP 3PAR StoreServ Storage Concepts Guide. NOTE: See the HP 3PAR Implementation Guides for recommended practices and detailed configuration information about using your specific host devices with the system. Modifying Port Parameters Use the HP 3PAR CLI controlport command to modify the FC ports and the Gigabit Ethernet ports used for the HP 3PAR Remote Copy Software over IP (RCIP) solution. Use the controliscsiport command to modify the iSCSI ports on the system. These commands control several aspects of the ports. Whenever you use these commands, you must use a sub-command specifying the operation you want to perform and include the port location. The HP 3PAR CLI displays the controller node port locations in the following format: ::. For example: 2:4:1. • Node : Valid node numbers are 0-7, depending on the number of nodes installed in your system. When viewing a system from the rear of a cabinet: ◦ F-Class nodes are numbered 0-3 from top to bottom. ◦ T-Class nodes are numbered 0-7 from left to right, top to bottom. ◦ StoreServ 10000 nodes are numbered 0-7 from left to right, bottom to top. ◦ StoreServ 7000 nodes are numbered 0-1 or 0-3 from bottom to top. • Slot : Valid node slot numbers are 0-9, depending on the class of nodes installed in your system. ◦ F-Class slots are numbered 0-5 from left to right. ◦ T-Class slots are numbered 0-7 from left to right.

5 Managing Ports and Hosts
Overview
The system sees a host as a set of initiator port World Wide Names (WWNs) or iSCSI Names.
Hosts that are physically connected to ports on the system are automatically detected. The FC port
WWNs and iSCSI port iSCSI Names are displayed in the HP 3PAR CLI. You can also add new
WWNs or iSCSI Names for unestablished host paths and assign them to a host before they are
physically connected. These WWNs or iSCSI Names do not need to be associated with target
ports on the system controller nodes. This allows for plug-and-play functionality that avoids the
need for manual reconfiguration after connecting new hosts.
FCoE connectivity is supported on HP 3PAR StoreServ 10000 Storage systems and HP 3PAR
StoreServ 7000 Storage systems through the use of Converged Network Adapters (CNA). CNA
ports can be configured to be used as FCoE or iSCSI ports.
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 time related to complex host
connections.
For more information about ports, hosts, and host personas, see the
HP 3PAR StoreServ Storage
Concepts Guide
.
NOTE:
See the HP 3PAR Implementation Guides for recommended practices and detailed
configuration information about using your specific host devices with the system.
Modifying Port Parameters
Use the HP 3PAR CLI
controlport
command to modify the FC ports and the Gigabit Ethernet
ports used for the HP 3PAR Remote Copy Software over IP (RCIP) solution. Use the
controliscsiport
command to modify the iSCSI ports on the system. These commands control
several aspects of the ports. Whenever you use these commands, you must use a sub-command
specifying the operation you want to perform and include the port location.
The HP 3PAR CLI displays the controller node port locations in the following format:
<Node>:<Slot>:<Port>
. For example:
2:4:1
.
Node
: Valid node numbers are 0-7, depending on the number of nodes installed in your
system. When viewing a system from the rear of a cabinet:
F-Class nodes are numbered 0-3 from top to bottom.
T-Class nodes are numbered 0-7 from left to right, top to bottom.
StoreServ 10000 nodes are numbered 0-7 from left to right, bottom to top.
StoreServ 7000 nodes are numbered 0-1 or 0-3 from bottom to top.
Slot
: Valid node slot numbers are 0-9, depending on the class of nodes installed in your
system.
F-Class slots are numbered 0-5 from left to right.
T-Class slots are numbered 0-7 from left to right.
