FCoE Boot from SAN

Provisioning Storage Access in the SAN
Storage access consists of zone provisioning and storage selective LUN
presentation, each of which is commonly provisioned per initiator WWPN. Two
main paths are available for approaching storage access:
 Pre-provisioning
 CTRL+R Method
Pre-provisioning
With pre-provisioning, note the initiator WWPN and manually modify fabric zoning
and storage selective LUN presentation to allow the appropriate access for the
initiator.
The initiator WWPN can be seen at the bottom of the pane in the FCoE boot
target configuration window.
The initiator WWPN can also be directly inferred from the FIP MAC address
associated with the interface(s) planned for boot. Two MAC addresses are printed
on stickers attached to the SFP+ cage on your adapter. The FIP MAC ends in an
odd digit. The WWPN is 20:00: + <FIP MAC>. For example, if the FIP MAC is
00:10:18:11:22:33, the WWPN is 20:00:00:10:18:11:22:33.
CTRL+R Method
The CTRL+R method allows you to use the boot initiator to bring up the link and
log in to all available fabrics and targets. Using this method, you can ensure that
the initiator is logged into the fabric or target before making provisioning changes,
and as such, can provision without manually typing in WWPNs.
1. Configure at least one boot target through CCM as described in
Pre-provisioning.
2. Allow the system to attempt to boot through the selected initiator.
NOTE
The default WWPN is 20:00: + <FIP MAC>. The default WWNN is 10:00: +
<FIP MAC>.
NOTE
In Dell FlexAddress™ configurations, the SAN or FIP MAC may be
overridden by the blade chassis management system.
