Fibreutils is a set of utility scripts for Linux that make certain operations, such as information gathering, easier. The following sections describe commands contained in the Fibreutils
package.
adapter_info
The adapter_info command lists information about the Fibre Channel adapters.
–I Lists all FC adapters in this system.
–L Lists all LUNs for each adapter.
–t Lists all targets seen by each adapter.
-m Lists each adapter’s model.
–v Verbose
–h Prints the help menu.
–d Prints LUN and verbose information for a specific device. The specific device should be a SCSI host number such as 0 or 6.
lssd
The lssd command lists all bound /dev/sd* devices.
–c Prints cached data instead of scanning.
–h Prints help message.
–l Prints inquiry page 0 x 83 UUID of devices.
–w Prints WWNN of devices.
lssg
The lssg command lists all bound /dev/sg* devices.
–c Prints cached data instead of scanning.
–h Prints help message.
–l Prints inquiry page 0 x 83 UUID of devices.
–w Print WWNN of devices.
hp_rescan
The hp_rescan command rescans LUNs on Hewlett Packard Enterprise supported Fibre Channel
adapters.
–a Rescans all adapters.
–h Prints help message
–i Rescans a specific adapter instance. The specific device should be a SCSI host number such as 0 or 6.
–l Lists all FC adapters.
–n Do not perform scsi remove-single-device when executing probe-luns.
