Configure SAN Components and Storage System
Before you set up your ESXi host to boot from a SAN LUN, configure SAN components and a storage
system.
Because configuring the SAN components is vendor-specific, refer to the product documentation for each
item.
Procedure
1 Connect network cable, referring to any cabling guide that applies to your setup.
Check the switch wiring, if there is any.
2 Configure the storage array.
a From the SAN storage array, make the ESXi host visible to the SAN. This process is often called
creating an object.
b From the SAN storage array, set up the host to have the WWPNs of the host’s adapters as port
names or node names.
c Create LUNs.
d Assign LUNs.
e Record the IP addresses of the switches and storage arrays.
f Record the WWPN for each SP.
Caution If you use a scripted installation process to install ESXi in boot from SAN mode, take
special steps to avoid unintended data loss.
Configure Storage Adapter to Boot from SAN
When you set up your host to boot from SAN, you enable the boot adapter in the host BIOS. You then
configure the boot adapter to initiate a primitive connection to the target boot LUN.
Prerequisites
Determine the WWPN for the storage adapter.
Procedure
u
Configure the storage adapter to boot from SAN.
Because configuring boot adapters is vendor-specific, consult your vendor documentation.
Set Up Your System to Boot from Installation Media
When setting up your host to boot from SAN, you first boot the host from the VMware installation media.
To boot from the installation media, change the system boot sequence in the BIOS setup.
