Make sure that the newly created /boot/initrams-* image or /boot/initrd-* image is selected in
Step 8.
the boot configuration file.For example, for grub it is /boot/grub/menu.lst and for grub2 it is /boot/
grub2/menu.cfg.
Step 9. Use the "Create host manually" procedure in the online help to check whether the hosts are
defined. Verify that each host type is either Linux DM-MP (Kernel 3.10 or later) if you enable the
Automatic Load Balancing feature, or Linux DM-MP (Kernel 3.9 or earlier) if you disable the
Automatic Load Balancing feature. If necessary, change the selected host type to the appropriate
setting.
Step 10. Reboot the host.
Configure the FC switches
Configuring (zoning) the Fibre Channel (FC) switches enables the hosts to connect to the storage array and
limits the number of paths. You zone the switches using the management interface for the switches.
Before you begin
• You must have administrator credentials for the switches.
• You must have used your HBA utility to discover the WWPN of each host initiator port and of each
controller target port connected to the switch.
For details about zoning your switches, see the switch vendor's documentation.
You must zone by WWPN, not by physical port. Each initiator port must be in a separate zone with all of its
corresponding target ports.
Step 1. Log in to the FC switch administration program, and then select the zoning configuration option.
Step 2. Create a new zone that includes the first host initiator port and that also includes all of the target
ports that connect to the same FC switch as the initiator.
Step 3. Create additional zones for each FC host initiator port in the switch.
Step 4. Save the zones, and then activate the new zoning configuration.
Determine host WWPNs and make the recommended settings
You install an FC HBA utility so you can view the worldwide port name (WWPN) of each host port.
Additionally, you can use the HBA utility to change any settings recommended in the Interoperability Matrix
document for the supported configuration.
Guidelines for HBA utilities:
• Most HBA vendors offer an HBA utility. You will need the correct version of HBA for your host operating
system and CPU. Examples of FC HBA utilities include:
– Emulex OneCommand Manager for Emulex HBAs
– QLogic QConverge Console for QLogic HBAs
• Host I/O ports might automatically register if the host context agent is installed.
Step 1. Download the appropriate utility from your HBA vendor's web site.
Step 2. Install the utility.
Step 3. Select the appropriate settings in the HBA utility.
Appropriate settings for your configuration are listed in the Interoperability Matrix document. Go to
