A storage administrator has provisioned a LUN from a storage system to a new host and created the appropriate zones. The server administrator now states that the host cannot see the new volume. Which

Pinging the storage system is irrelevant for Fibre Channel SANs, as Fibre Channel uses its own protocols for storage traffic, not IP.

Checking the multipathing level would be done after the host can see the LUN, as multipathing manages multiple paths to an already visible storage device.

Submitting a change ticket for another volume would not address the current issue of the existing LUN not being visible and is a premature action before proper troubleshooting.

LUN masking is typically configured on the storage array itself to control which hosts can access specific LUNs. If the LUN has been provisioned and zoning established, but the host still can't see the volume, the most immediate and critical step to check is whether the LUN has been properly masked and presented to the host's WWN(s) on the storage system. Incorrect or missing LUN masking will prevent the host from discovering the LUN, even if physical connectivity and zoning are correct.
