• Persistent bindings are necessary in a fabric topology and are used to bind a SCSI target ID
to a particular WWPN (of an array port). This is required to guarantee that the SCSI target
IDs will remain the same when the system is rebooted. Persistent bindings can be set by editing
the configuration file or by using the lputil utility. The following example illustrates the
binding of target 20 (lpfc instance 2) to WWPN 50060e8003285301 and the binding of
target 30 (lpfc instance 0) to WWPN 50060e8003285311:
fcp-bind-WWPN="50060e8003285301:lpfc2t20",
"50060e8003285311:lpfc0t30";
(Replace the WWPNs in the previous example with the WWPNs for your array ports.)
• For each LUN that needs to be accessed, add an entry to the /kernel/drv/sd.conf file.
For example, assume you want to access LUNs 1 and 2 through both paths. You would add
the following entries (preferably at the end of the file):
name="sd" parent="lpfc" target=20 lun=1;
name="sd" parent="lpfc" target=20 lun=2;
name="sd" parent="lpfc" target=30 lun=1;
name="sd" parent="lpfc" target=30 lun=2;
• Perform a reconfiguration reboot to implement the changes to the configuration files.
• If LUNs have been preconfigured in the /kernel/drv/sd.conf file, use the devfsadm
command to perform LUN rediscovery after configuring LUNs as explained in “Defining the
paths” (page 13).
Configuring QLogic FCAs with the qla2300 driver
NOTE: The qla2300 driver cannot be used with Oracle StorEdge Traffic Manager/Oracle
Storage Multipathing. To configure a QLogic FCA using the Oracle SAN driver stack, see
“Configuring FCAs with the Oracle SAN driver stack” (page 72).
Contact your HP representative to determine which QLogic FCAs and driver version HP supports
with the qla2300 driver. The qla2300 driver is not supported on x86 architecture. Configure
QLogic FCAs with the qla2300 driver as follows:
• Ensure you have the latest supported version of the qla2300 driver (available from http://
www.qlogic.com).
• Edit the /kernel/drv/qla2300.conf driver configuration file to set up the FCA for a SAN
infrastructure:
hba0-connection-options=1;
hba0-link-down-timeout=30;
hba0-persistent-binding-configuration=1;
• Persistent bindings are necessary in a fabric topology and are used to bind a SCSI target ID
to a particular WWPN (of an array port). This is required to guarantee that the SCSI target
IDs will remain the same when the system is rebooted. Persistent bindings can be set by editing
the configuration file or by using the SANsurfer utility. The following example illustrates the
binding of target 20 (hba instance 0) to WWPN 50060e8003285301 and the binding of
target 30 (hba instance 1) to WWPN 50060e8003285311:
hba0-SCSI-target-id-20-fibre-channel-port-name="50060e8003285301";
hba1-SCSI-target-id-30-fibre-channel-port-name="50060e8003285311";
(Replace the WWPNs in the previous example with the WWPNs for your array ports.)
• With qla2300 v4.20, 5.02, or later:
Verify that the following entry is present in /kernel/drv/sd.conf:
