HP 3PAR X9000 File Serving Software (IBRIX) Implementation Guide (QL226-96987, June 2013)

Once you install the QLogic SANsurfer FC CLI utility for each of the HBA ports, set the correct port
connection type (direct --> loop, fabric --> point) by running the following commands:
• For fabric connection:
# /opt/QLogic_Corporation/SANsurferCLI/scli -n X CO 1
• For direct connection:
# /opt/QLogic_Corporation/SANsurferCLI/scli -n X CO 0
where X is equal to the HBA FC port #, the HBA port numbers start with number 0.
For example, to set the HBA ports 1 and 3 to Point to Point/Fabric topology, run the following
commands:
# /opt/Qlogic_Corporation/SANsurferCLI/scli -n 1 CO 1
# /opt/Qlogic_Corporation/SANsurferCLI/scli -n 3 CO 1
To set the same HBA ports 1 and 3 to Direct topology, run the following commands:
# /opt/Qlogic_Corporation/SANsurferCLI/scli -n 1 CO 0
# /opt/Qlogic_Corporation/SANsurferCLI/scli -n 3 CO 0
You can verify the setting by running the following command:
# /opt/Qlogic_Corporation/SANsurferCLI/scli -I 1
# /opt/Qlogic_Corporation/SANsurferCLI/scli -I 3
Refer to the SANsurfer FC CLI utility program release notice for other command line options to
change the following settings:
• LUNs per Target: 256
• Data Rate: 4 (Auto Negotiate)
Setting the SCSI Timeout
The SCSI timeout needs to be set at 60 seconds in order for the HP 3PAR StoreServ Storage to
operate properly and with Red Hat 5 servers. The SCSI timeout is set to 60 seconds by default and
no configuration changes are needed.
Setting Up Multipathing Software
On the HP StoreAll 9300 Gateway Storage nodes, modify the installed Device Mapper
Configuration file to enable multipath for the HP 3PAR StoreServ Storage.
Modifying the /etc/multipath.conf File
The /etc/multipath.conf file is used by device mapper where the multipathing parameters
have been set. The default installed /etc/multipath.conf file must be edited with the following
changes for connecting to an HP 3PAR array. Entries listed in the multipath.conf file override
the default kernel parameters for dm-multipath. In general, the kernel defaults are sufficient with
the exception of the devices entries for HP 3PAR.
1. Ensure that the user_friendly_names is in the default structure in the file.
