An engineer must implement a Cisco UCS system at a customer site.
One of the requirements is to implement SAN boot.
The storage system maps the source WWPN to a unique LUN.
Which method does Cisco recommend to configure the SAN boot?

Cisco recommends creating a SAN boot policy in which every initiator is mapped to a different target LUN to configure SAN boot in a Cisco UCS system.
SAN boot is a method of booting a server from a storage area network (SAN) instead of a local disk. This method allows for centralized management of boot images and eliminates the need for local storage on the server.
In a SAN boot configuration, the server's virtual host bus adapters (vHBAs) are configured to access the storage system and map the source world wide port names (WWPNs) to a unique LUN. A SAN boot policy is used to define how the vHBAs are configured for booting.
Option A, defining the vHBAs as bootable and leaving the boot target definition empty, is not recommended because it does not provide any specific instructions on which LUN the server should boot from.
Option C, defining the vHBAs as bootable and leaving the default values on the boot target definition, is also not recommended because it does not provide any specific instructions on which LUN the server should boot from.
Option D, creating a SAN boot policy in which every initiator is mapped to the same target LUN, is not recommended because it does not provide the necessary redundancy and fault tolerance in case the LUN becomes unavailable.
Therefore, option B, creating a SAN boot policy in which every initiator is mapped to a different target LUN, is the recommended method for configuring SAN boot in a Cisco UCS system. This approach provides redundancy and fault tolerance by mapping each initiator to a unique target LUN, ensuring that if one LUN becomes unavailable, the server can still boot from a different LUN.
