Explanation
The output shows that the LUN access failure is occurring, which usually happens when the storage array has not been properly configured to allow access to the LUN for the server's WWPN (World Wide Port Name). LUN masking is a method used on the storage array to ensure that specific servers can access specific LUNs. In this case, the LUN is not visible because it has not been unmasked for the By unmasking the LUN on the storage array for the WWPN of the Cisco UCS blade, the LUN will be accessible, resolving the boot issue.
