Configuring Qlogic Fcas With The Qla2300 Driver - HP 6100 User Manual

3. If using a single FCA and no multipathing, edit the following parameter to reduce the risk of
data loss in case of a controller reboot:
nodev-tmo=120;
4. If using Veritas Volume Manager (VxVM) DMP for multipathing (single or multiple FCAs), edit
the following parameter to ensure proper VxVM behavior:
no-device-delay=0;
5. In a fabric topology, use persistent bindings to bind a SCSI target ID to the world wide port
name (WWPN) of an array port. This ensures that the SCSI target IDs remain the same when
the system reboots. Set persistent bindings by editing the configuration file or by using the
lputil utility.
NOTE:
same target ID on each host in the SAN.
The following example for an EVA4x00/6x00/8x00 illustrates the binding of targets 20 and
21 (lpfc instance 2) to WWPNs 50001fe100270938 and 50001fe100270939, and the
binding of targets 30 and 31 (lpfc instance 0) to WWPNs 50001fe10027093a and
50001fe10027093b:
fcp-bind-WWPN="50001fe100270938:lpfc2t20",
NOTE:
6. For each LUN that will be accessed, add an entry to the /kernel/drv/sd.conf file. For
example, if you want to access LUNs 1 and 2 through all four paths, add the following entries
to the end of the file:
name="sd" parent="lpfc" target=20 lun=1;
name="sd" parent="lpfc" target=21 lun=1;
name="sd" parent="lpfc" target=30 lun=1;
name="sd" parent="lpfc" target=31 lun=1;
name="sd" parent="lpfc" target=20 lun=2;
name="sd" parent="lpfc" target=21 lun=2;
name="sd" parent="lpfc" target=30 lun=2;
name="sd" parent="lpfc" target=31 lun=2;
7. Reboot the server to implement the changes to the configuration files.
8. If LUNs have been preconfigured in the /kernel/drv/sd.conf file, use the devfsadm
command to perform LUN rediscovery after configuring the file.
NOTE:
Multipathing. To configure an Emulex FCA using the Sun SAN driver stack, see

Configuring QLogic FCAs with the qla2300 driver

See the latest Enterprise Virtual Array release notes or contact your HP representative to determine
which QLogic FCAs and which driver version HP supports with the qla2300 driver. To configure
QLogic FCAs with the qla2300 driver:
1. Ensure that you have the latest supported version of the qla2300 driver (see
www.qlogic.com).
HP recommends that you assign target IDs in sequence, and that the EVA has the
"50001fe100270939:lpfc2t21",
"50001fe10027093a:lpfc0t30",
"50001fe10027093b:lpfc0t31";
Replace the WWPNs in the example with the WWPNs of your array ports.
The lpfc driver is not supported for Sun StorEdge Traffic Manager/Sun Storage
89).
