Configuring an Adapter to Boot-from-SAN

This section describes how to configure a QLogic 8100 Series Adapter to boot the RHEL 5 operating system from the SAN.

1.Install the QLogic 8100 Series Adapter, and update the firmware, if necessary. For information about updating the firmware, refer to “Firmware Upgrades” on page 4-21.

2.Connect the SAN components in a single-path topology as shown in Figure 8-12.If a multipath topology is required, make the necessary additions and connections after the initial operating system installation.

3.Power up the server.

If this is a BIOS server, press CTRL+Q or ALT+Q while the server is booting, to open the QLogic Fast!Util BIOS configuration utility. Proceed to Step 4.

If this is a UEFI server, select EFI Shell from the EFI Boot Manager menu while the server is booting. Proceed to Step 5.

4.Configure the BIOS server. For information about configuring an UEFI server, proceed to Step 5.

a.Configure the switch with a zone that includes the adapter port and one storage array port, using either soft zoning (WWPN-based) or hard zoning (port number-based), and enable the zone. Soft zoning is recommended because, if a server malfunctions, you can move the adapter to another host without reconfiguration.

b.Create an appropriately-sized LUN on the storage array. The LUN size depends on the operating system to be installed. Add this LUN to a host group containing the QLogic adapter.

c.Set the host type/mode for the host group that corresponds to the operating system to be installed. The boot LUN should be LUN 0. For information about using a LUN other than LUN 0, refer to “Booting from SAN Using a LUN Other Than LUN 0” on page 8-40.

d.In the QLogic Fast!UTIL BIOS configuration utility on the server, select the adapter port in the Select Host Adapter menu, and then press

ENTER.

e.Select Configuration Settings from the Fast!UTIL Options menu, and press ENTER.

f.Select Adapter Settings from the Configuration Settings menu, and then press ENTER.

g.Change Host Adapter BIOS to Enabled in the Adapter Settings menu, and press ENTER.
