HP 3PAR Solaris Implementation Guide

2 Configuring the HP 3PAR StoreServ Storage for Fibre
Channel
This chapter explains how to establish a Fibre Channel connection between the HP 3PAR StoreServ
Storage and a Solaris host and covers HP 3PAR OS 3.1.x and 2.3.x. For information on setting
up the physical connection for a particular HP 3PAR StoreServ Storage, see the appropriate HP
installation manual.
Required
If you are setting up a fabric along with your installation of the HP 3PAR StoreServ Storage, see
“Setting Up and Zoning the Fabric” (page 10) before configuring or connecting your HP 3PAR
StoreServ Storage.
Configuring the HP 3PAR StoreServ Storage Running HP 3PAR OS 3.1.x
or OS 2.3.x
This section describes how to connect the HP 3PAR StoreServ Storage to an Solaris host over a
Fibre Channel network when running HP 3PAR OS 3.1.x or OS 2.3.x.
Required
The following setup must be completed before connecting the HP 3PAR StoreServ Storage port to
a device.
Configuring Ports on the HP 3PAR StoreServ Storage in a Direct Topology
To set up the HP 3PAR StoreServ Storage ports for a direct connection, issue the following set of
commands with the appropriate parameters for each direct connect port.
# controlport offline <node:slot:port>
# controlport config host -ct loop <node:slot:port>
# controlport rst <node:slot:port>
The -ct loop parameter specifies a direct connection.
NOTE: While the server is running, HP 3PAR StoreServ Storage ports that leave (e.g., due to an
unplugged cable) and return will be tracked by their World Wide Name (WWN). The WWN of
each port is unique and constant which ensures correct tracking of a port and its LUNs by the host
HBA driver.
If a fabric zoning relationship exists such that a host HBA port has access to multiple targets (for
example, multiple ports on the HP 3PAR StoreServ Storage), the driver will assign target IDs (cxtxdx)
to each discovered target in the order that they are discovered. The target ID for a given target
can change in this case as targets leave the fabric and return or when the host is rebooted while
some targets are not present.
Configuring Ports on the HP 3PAR StoreServ Storage in a Fabric Topology
CAUTION: Before taking a port offline in preparation for a fabric connection, you should verify
that the port has not been previously defined and that it is not already connected to a host, as this
would interrupt the existing host connection. If an HP 3PAR StoreServ Storage port is already
configured for a fabric connection, you can ignore step 2, since you do not have to take the port
offline.
