SAN Boot Configuration
This section describes the procedure for installing the SAN boot environment and provides design notes.
Only field engineers should perform the tasks described in this section for this solution, including the options
provided by Cisco. Customers must not perform these tasks under any circumstances:
●
Newly install or move equipment
●
Remove the front, rear, and side covers
●
Install or remove built-in options
●
Connect or disconnect external interface cables
●
Perform maintenance (including repair and periodic diagnosis and maintenance operations)
Overview of Steps for Configuring the SAN Boot Environment
This section describes the flow for configuring the SAN boot environment for the Cisco C880 M4 Server. Follow
these steps to configure the SAN boot environment.
Note the following:
●
Use a single-path configuration (connection with only one Fibre Channel cable) until the installation of the
OS and the multipath driver is complete.
●
After installing the OS and multipath driver, connect the Fibre Channel cable to restore the original state.
Then power on the partition of the Cisco C880 M4 again.
●
Register the logical unit number (LUN) that is the destination of the OS installation in all the host bus
adapters (HBAs) to be used to start the system.
●
Before turning on the power to the partition of the Cisco C880 M4, confirm that the SAN storage in which
the OS will be stored and the Fibre Channel switch are completely ready.
1. Design the SAN boot environment:
a. Create a diagram for Fibre Channel cabling between the SAN storage unit and the Cisco C880 M4 in
which the SAN boot environment is to be configured. Also create a zone design drawing.
b. Design the RAID (LUN_R) settings and partition (LUN) for the SAN storage that stores the target OS
for SAN boot.
2. Configure the settings for the Cisco C880 M4:
a. Change the Unified EFI (UEFI) setting of the Cisco C880 M4 Server and the HBA UEFI and extended
BIOS settings of the Fibre Channel card.
b. Record the World Wide Name (WWN) for each Fibre Channel port. Also record the World Wide Node
Name (WWNN) as required.
3. Configure the settings for the SAN environment:
a. Following the Fibre Channel cabling diagram created in step 1, install the SAN storage and Fibre
Channel switch and connect them with cables.
b. Based on the RAID setting, partition design, and zone information configured in step 1 and on the
WWN information recorded in step 2, configure the settings for the SAN storage and Fibre Channel
switches.
c. In the configuration of the HBA UEFI and extended BIOS of the Fibre Channel card included in the
Cisco C880 M4 Server, search for the WWN of the connection destination SAN storage and set it.
