Figuring out the affiliation between a Logical Unit Quantity (LUN) and a particular controller inside a Linux surroundings includes figuring out the trail by way of which the storage is accessed. This course of usually includes inspecting the system’s storage configuration, paying shut consideration to the gadget names and their corresponding {hardware} identifiers. For instance, analyzing the output of instructions akin to `lsscsi`, `multipath -ll`, or querying the contents of `/sys/block` can reveal how storage units are introduced and related to the host system.
Understanding this mapping is essential for a number of causes. It facilitates correct troubleshooting of storage-related points, permits efficient efficiency monitoring, and ensures correct configuration of multipathing options for top availability. Traditionally, this mapping relied on direct SCSI connections. Nonetheless, with the appearance of applied sciences like Fibre Channel, iSCSI, and NVMe-oF, the method has change into extra complicated, requiring a deeper understanding of the storage networking stack.
