HP 3PAR Citrix Implementation Guide

SCLI Command Line Interface
Use scli with the in-box QLogic driver from the Citrix installation.
• For FC, the scli utility is installed under /opt/QLogic_Corporation/SANsurferCLI.
• For FCoE, the scli utility is installed under /opt/QLogic_Corporation/
QConvergeConsoleCLI.
• Verify version installed with rpm.
Example:
# rpm -qa scli
scli-1.7.1-23
Make the following selection from the scli menu:
• Select HBA Parameters from the Main Menu.
Modifying the qlport_down_retry Parameter to a Value of 10
The scli utility refers to this parameter as Port Down Retry Count. See the documentation provided
by QLogic for details about the scli tool.
To set the value to 10, complete the following steps from the scli menu.
1. Select Main Menu→HBA Parameters→Configure HBA Parameters.
2. Select Port Down Retry Count from the Configure Parameters menu and set it to 10.
3. Select Commit Changes from the Configure Parameters menu.
4. Repeat Step 1 through Step 3 for each HBA installed.
5. To verify changes, use Display HBA Parameters from the HBA Parameters main menu.
6. Add options qla2xxx qlport_down_retry=10 to /etc/modprobe.conf
7. After rebooting the host, check
/sys/module/qla2xxx/parameters/qlport_down_retry to confirm the changes.
NOTE: If the HP 3PAR StoreServ Storage array is running an HP 3PAR OS version earlier
than OS 3.1.3, set the qlport_down_retry setting to 1 rather than 10.
Example:
# cat /sys/module/qla2xxx/parameters/qlport_down_retry
10
Setting Up Multipathing Software
HP supports Device-mapper as the multipath solution for Citrix.
Setting Up Device-mapper
Multipath tools and Device-mapper packages are installed during default Citrix OS installation.
Check for installed Device-mapper packages by issuing rpm -qa |grep device-mapper:
# rpm -qa|grep device-mapper
device-mapper-1.02.39-1.el5_5.2
device-mapper-event-1.02.39-1.el5_5.2
device-mapper-multipath-0.4.7-34.xs651
